Weekly Australian Climate,
Water and Agricultural Update

Key issues

  • During the week ending 18 August 2021, high pressure systems dominated southern Australia, resulting in little rainfall across much of the continent. Cold fronts brought rainfall to western Tasmania and parts of southern Victoria, and low-pressure systems produced isolated rainfall for north-eastern Australia.
  • As at 28 July 2021 global production conditions were generally favourable. A lack of precipitation and excessive heat has affected the production potential of wheat and corn, and to a lesser extent soybeans in some key grain exporters and importers.
  • Production conditions for wheat in particular have declined further during July for some key grain exporters. This represents a deterioration in conditions compared to what was expected back in April, which were used to formulate ABARES forecasts of global grain supplies and world prices in its June 2021 edition of Agricultural commodities.
  • The global climate outlook indicates that average to above average rainfall is more likely between September and November 2021 for some of the world's major grain-producing and oilseed-producing regions. If realised, this is likely to benefit corn, soybeans, sunflower, millet, rice, sorghum and cotton production and wheat and rapeseed planting in the northern hemisphere. In Australia, this positive outlook will support winter wheat and canola production and corn, cotton, soybeans, sunflower planting.
  • However, below average rainfall is more likely across much of Argentina and southern Brazil. This would adversely affect the development of wheat crops, and the planting of corn, soybeans, sorghum, cotton, sunflower, rice and millet. Below average rainfall between September and November 2021 is also more likely for parts of the Russian Federation, China and the United States of America. In these northern hemisphere growing regions, this is likely to benefit the harvest of spring wheat and canola, but adversely affect the development of corn, cotton, soybeans, sorghum and sunflower.
  • High pressure systems are likely to bring clear skies and dry conditions across much of eastern Australia over the next eight days. Parts of southern Australia are expected to receive rainfall from cold fronts moving off the Southern Ocean.
  • Water storage in the Murray–Darling Basin (MDB) increased by 240 gigalitres (GL) between 10 August 2021 and 17 August 2021. The current volume of water held in storage is 19,869 GL, which represents 78% of total capacity. This is 52% or 6,761 GL more than at the same time last year.
  • Allocation prices in the Victorian Murray below the Barmah Choke increased from $113 per ML on 6 August 2021 to $117 per ML on 13 August 2021. Prices are lower in the Goulburn-Broken, Murrumbidgee, and regions above the Barmah choke due to the binding of the Goulburn intervalley trade limit, Murrumbidgee export limit, and Barmah choke trade constraint.

Rainfall this week

During the week ending 18 August 2021, high pressure systems dominated southern Australia, resulting in little rainfall across much of the continent. Cold fronts brought rainfall to western Tasmania and parts of southern Victoria, and low-pressure systems produced isolated rainfall for north-eastern Australia.

Rainfall totals of between 10 and 50 millimetres were recorded across isolated parts of New South Wales, Queensland, southern Victoria, the south-east of South Australia and Western Australia. Rainfall totals in excess of 50 millimetres were recorded in isolated parts of northern Queensland and western Tasmania.

In cropping regions, rainfall totals of between 10 and 15 millimetres were recorded across isolated parts of New South Wales and Victoria. Little to no rainfall was recorded in cropping regions of much of the remainder New South Wales and Victoria, Queensland, South Australia and Western Australia.

The dry conditions across most of Australia’s cropping regions will be a reprieve from substantial rainfall totals already recorded this season. A second week of little to no rainfall for much of eastern Australia has allowed growers to access fields to apply urea and spray for pests and diseases. Parts of Western Australia had been struggling with waterlogging, but clear weather over the past week likely allowed for drying of saturate soils.

Global production conditions and climate outlook

Crop production is affected by long-term trends in average rainfall and temperature, interannual climate variability, shocks during specific growth stages, and extreme weather events (IPCC 2012). Some crops are more tolerant than others to certain types of stresses, and at each growth stage, different types of stresses affect each crop species in different ways.

The precipitation anomalies and outlooks presented here give an indication of the current and future state of production conditions for the major grain and oilseed producing countries which are responsible for over 80% of global production. This is an important input to assessing the global grain supply outlook.

July precipitation percentiles and current production conditions

As of the end of July 2021, rainfall was generally favourable for the world’s major grain and oil producing regions.

In the northern hemisphere, July precipitation was above average in parts of central Africa, south-western and north-eastern China, western Europe, India, Ukraine, Turkey, and parts of southern and eastern United States of America.

Precipitation was below average across much of southern Canada, the north of the United States of America, northern Europe, and the west of the Russian Federation. Precipitation was generally average across the remainder of major grain and oil producing regions in the northern hemisphere.

In the southern hemisphere, July precipitation was below average across much of Argentina and parts of southern Brazil. Precipitation was generally average to above average across the remainder of major grain and oil producing regions in the southern hemisphere.

As at 28 July 2021 global production conditions were generally favourable. However, a lack of precipitation and excessive heat has affected the production potential of wheat, corn and soybeans in some key grain exporting and importing countries.

Conditions for wheat development were generally favourable in Australia, Argentina, China, the European Union, United Kingdom, and Ukraine. Dry and unseasonably hot temperatures have resulted in variable production prospects across much of Canada, Kazakhstan, Turkey, the Russian Federation, and for much of northern and parts of central United States of America (US).

Conditions for corn in Argentina were generally favourable as harvest wraps up for the late-planted crop. In Brazil, production potential is mixed due to excessive dryness and frosts during the critical reproductive stage as harvesting commences. In Mexico production conditions are favourable as harvest wraps up for the autumn-winter crop and for the sowing of the spring-summer crop. Conditions were favourable for crop development in the European Union, India, Ukraine, and the Russian Federation. In the US, production potential is mixed as persistent hot and dry conditions extend across much of the northern Corn Belt. In China, production potential is also mixed as excess rainfall and flooding affect areas in the northeast and persistent dry affects crop in the northwest.

Conditions for rice were favourable for crop development in China and the US. Favourable growing conditions have supported production prospects for dry-season rice in Indonesia and wet-season rice in Vietnam. Growing conditions are also favourable in India, the Philippines and Thailand.

Production conditions for soybeans are mixed in Canada and in northern and western areas of the Mid-West of the US, as hot and dry conditions persist. Production conditions are favourable across remaining soybean producing regions.

The global climate outlook for September to November 2021 indicates that average to above average rainfall is more likely for most of the world's major grain-producing and oilseed-producing regions. Outlooks and potential production impacts for the major grain and oilseed producing countries are presented in the table.

Rainfall outlook and potential impact on the future state of production conditions between  September and November 2021
Region September-November rainfall outlook  Potential impact on production
Argentina Below average rainfall is expected across most of Argentina between September to November 2021. Below average rainfall is likely to adversely affect the heading and filling of wheat and the planting of corn, cotton and soybeans through September and October. These conditions may also adversely impact early corn silking, and the planting of soybeans, sunflower, rice, sorghum and millet in November. 
Black Sea Region Kazakhstan and Ukraine - No strong tendency towards either above or below average rainfall between September to November 2021.
The Russian Federation - Below average rainfall is expected across central and southern regions
Below average rainfall is likely to support spring wheat harvesting in the north-east of Russia and early cotton harvesting in southern regions. Average rainfall across Kazakhstan and Ukraine is likely to support winter wheat and rapeseed planting in September, and corn and sunflower filling in September and October.
Brazil Above average rainfall is more likely in northern Brazil while below average rainfall is more likely across the south of Brazil. Below average rainfall in parts of southern Brazil is likely to adversely affect wheat filling leading up to harvest in October, as well as corn and soybean planting and development in September and October. This may also affect the planting of groundnuts, sorghum, cotton, sunflower, rice and millet in November. 
Canada There is no strong tendency towards below or above average rainfall across much of Canada between September to November 2021. Average rainfall is unlikely to be sufficient to increase the yield potential of corn, soybeans and sunflower at the grain filling and maturing stage through September and October. 
China Above average rainfall is likely across much of southern China and below average across western and north-eastern China between September to November 2021. Below average rainfall is likely to adversely affect the development and harvest of cotton, corn, sorghum, soybean, sunflower, groundnuts and spring wheat across north-eastern and western China. In southern China, average to above average rainfall is likely to support late rice heading in September and planting of winter wheat and rapeseed in October. 
Europe Below average rainfall more likely for parts of southern Europe between September to November 2021. Below average rainfall may adversely impact the development and harvest of corn, cotton and sorghum in southern Europe. Below average rainfall may also impact winter wheat and rapeseed planting in parts of southern and eastern Europe during October and November.  
South Asia (India) Above average rainfall between September to November 2021 is likely across much of India. Average to above average rainfall is likely to benefit cotton blooming in the south during September and corn, sorghum, rice, millet, groundnuts and sunflower filling in September leading up to harvest in October and November, and winter wheat and rapeseed planting in November. 
Southeast Asia (SEA) Above average rainfall is likely for northern SEA, with a strong likelihood of above average rainfall for Indonesia between September to November 2021. Above average rainfall in SEA is likely to support corn and rice maturing during September leading up to harvest in October. 
The United States of America Above average rainfall is more likely for parts of eastern US and below average rainfall is more likely across much of the centre and the western half of the US. Below average rainfall is likely to adversely affect the filling and maturing of soybeans, sunflower, millet, cotton, rice, corn, sorghum and groundnuts in September leading up to harvest in October and November. 

Rainfall forecast for the next eight days

High pressure systems are likely to bring clear skies and dry conditions across much of eastern Australia over the next eight days. Parts of southern Australia are expected to receive rainfall from cold fronts moving off the Southern Ocean.

Rainfall totals of between 10 and 50 millimetres are forecast for parts of eastern New South Wales, southern and eastern Victoria, the south-east of South Australia, the south-west of Western Australia and eastern Tasmania. Rainfall in excess of 50 millimetres is expected in north-eastern Queensland, parts of south-west Western Australia and western Tasmania.

In Australian cropping regions, rainfall totals of between 10 and 25 millimetres are expected in parts of eastern New South Wales, southern Victoria, central South Australia and parts of the south-west of Western Australia. Little to no rainfall is forecast for much of New South Wales, Queensland, northern Victoria, much of South Australia and Western Australia cropping regions during the next 8-days.

The dry conditions across most cropping regions are expected to have a positive impact for crop development. Most regions have average to above-average plant available soil moisture, which will support ongoing crop development. In areas previously affected by waterlogging, the continued dry conditions will allow proper drainage of soils and is likely to positively impact crop growth. The dry conditions will also allow greater access to paddocks for crop management activities.

Key issues

  • During the week ending 11 August 2021, low pressure systems and cold fronts brought rainfall to parts of western and southern Australia. High pressure systems and clear skies, on the other hand, resulted in little to no rainfall across much of eastern, central and northern Australia.
  • For the 3 months to July 2021, low rainfall totals limited pasture production across parts of southern and northern Australia. In contrast, average or better rainfall and generally average soil moisture benefitted pasture production across large areas of western and eastern Australia.
  • The Bureau of Meteorology reports that the negative Indian Ocean Dipole (IOD) event continues. A negative IOD event increases the chance of above average rainfall for southern and eastern Australia and the far north during winter and spring. It is also typically associated with an early onset of northern rainfall.
  • The outlook for September 2021 indicates that there is a 75% chance of rainfall totals between 10 and 100 millimetres across parts of eastern, south-western and far southern Australia. Rainfall totals in excess of 100 millimetres are expected across alpine regions of New South Wales and Victoria, and western Tasmania.
  • The rainfall outlook for spring 2021 (September to November) suggests there is a greater than 70% chance of exceeding average rainfall across much of New South Wales, Queensland, Victoria, South Australia and the Northern Territory. There is an increased chance of below average rainfall across the north and part of south-west Western Australia and western Tasmania during spring 2021.
  • The influence of slow-moving high-pressure systems is likely to bring clear skies and dry conditions across much of Australia over the next eight days. Rainfall is likely to be limited to west facing southern coastlines and onshore flow will bring showers to isolated areas of Australia’s eastern coast.
  • Little to no rainfall is forecast for most of Australia’s cropping regions during the next 8-days. These dry conditions across most cropping regions will allow for drying of saturated soil profiles in some areas, reducing the impact of waterlogging and associated water-damage. Crop development is expected to progress unimpeded with high levels of plant available moisture in most areas provided by previous heavy falls.
  • Water storage in the Murray–Darling Basin (MDB) increased by 317 gigalitres (GL) between 4 August 2021 and 11 August 2021. The current volume of water held in storage is 19,638 GL, which represents 78% of total capacity. This is 54% or 6,889 GL more than at the same time last year.
  • Allocation prices in the Victorian Murray below the Barmah Choke decreased from $125 per ML on 30 July 2021 to $113 per ML on 6 August 2021. Prices are lower in the Goulburn-Broken, Murrumbidgee, and regions above the Barmah choke due to the binding of the Goulburn intervalley trade limit, Murrumbidgee export limit, and Barmah choke trade constraint.

Rainfall this week

During the week ending 11 August 2021, low pressure systems and cold fronts brought rainfall to parts of western and southern Australia. High pressure systems and clear skies, on the other hand, resulted in little to no rainfall across much of eastern, central and northern Australia.

Rainfall totals of between 10 and 50 millimetres were recorded across isolated parts of Queensland, Victoria, southern South Australia, much of the south-west of Western Australia and western Tasmania. Rainfall totals in excess of 50 millimetres were recorded in isolated parts of south-west Western Australia and western Tasmania.

In cropping regions, rainfall totals of between 10 and 50 millimetres were recorded across much of Western Australia. Little to no rainfall was recorded in cropping regions of New South Wales, Queensland, Victoria and South Australia.

Continued wet conditions in the south-west of Western Australia has likely exacerbated waterlogging in some areas, negatively impacting crop growth. The drier conditions in eastern cropping regions provided a welcome break, with ample soil moisture to support ongoing plant development. Recent wet conditions across Australia have restricted access to fields and delayed spraying of crops for pest and disease control and applications of urea. A run of dry weather in some eastern and western cropping regions will be required to allow field access, otherwise aerial spraying may become necessary.

Pasture Growth

Pasture growth during the May to July period is typically low across large areas of central and northern Australia as it enters a seasonally low growth period due to cooler temperatures and little to no rainfall. Across southern Australia, May to July pasture growth influences the number of livestock than can be supported without supplementary feeding over winter and the level of reliance on hay and grain during this period.

For the 3 months to July 2021, low rainfall totals limited pasture production across parts of southern and northern Australia. In contrast, average or better rainfall and generally average soil moisture benefitted pasture production across large areas of western and eastern Australia.

Modelled pasture growth was extremely low to below average across parts of western New South Wales, parts of central Queensland, western Victoria, eastern South Australia, central and northern Western Australia, and parts of central Northern Territory. As a result, livestock producers across parts of western New South Wales, western Victoria and eastern South Australia will be heavily reliant on rainfall over the remainder of winter to build soil moisture levels and supplementary feed to maintain current stock numbers.

In contrast, modelled pasture growth was above average to extremely high across large areas of central and northern New South Wales, eastern Queensland, and large areas of Western Australia. This growth is likely to enable farmers to continue to rebuild stock numbers and provide opportunities to replenish fodder supplies during spring.

Climate Drivers

Throughout winter the climate drivers with the largest potential impact on Australia’s climate patterns are the El Niño–Southern Oscillation (ENSO), the Indian Ocean Dipole (IOD) and the Southern Annular Mode (SAM). These climate drivers will likely influence the outlook for Australia’s winter cropping season.

The Bureau of Meteorology reports that the negative Indian Ocean Dipole (IOD) event continues. A negative IOD event increases the chance of above average rainfall for southern and eastern Australia and the far north during winter and spring. It is also typically associated with an early onset of northern rainfall.

ENSO conditions, on the other hand, remain neutral according to most oceanic and atmospheric indicators, reducing its influence on Australia’s climate. International climate models surveyed by the Bureau of Meteorology agree that ENSO conditions are likely to remain neutral throughout August. Three of the seven models, however, expect the development of a La Niña event in mid-to-late spring. Only two models expect a La Niña event in December. The SAM is currently positive but is expected to rapidly return to neutral values over the coming days and remain there in the coming weeks. It is therefore unlikely to have a significant influence on Australia’s climate.

Sea surface temperature anomalies were close to average across the tropical Pacific Ocean over the previous week. Warm anomalies in the western Pacific have weakened slightly, while warm anomalies near the Maritime Continent and along the east coast of Australia have persisted. Neutral Pacific equatorial sea surface temperatures are associated with neutral ENSO conditions.

Warm sea surface temperature anomalies have persisted near Western Australia and Indonesia. Meanwhile, sea surface temperatures in the western Indian Ocean largely cooled slightly over the past week. The warm anomalies in the eastern Indian Ocean and the ocean surrounding Australia underpin the continuation of the negative IOD event.

Map showing the global sea surface temperature observations difference from average during the previous week. The climatology baseline used is 1961 to 1990. Image provided by the Bureau of Meteorology. Please refer to accompanying text for a more detailed description.

As at 1 August 2021, the Indian Ocean Dipole (IOD) weekly value was -0.76°C. The IOD index has generally been below the negative IOD threshold (−0.4 °C) since mid-May. A negative IOD, and warmer sea surface temperatures in the eastern Indian Ocean, is associated with above average rainfall for much of southern Australia in winter and spring. It also increases the chances of below average maximum temperatures in southern Australia, while increasing the chances of above average minimum and maximum temperatures in northern Australia.

The majority of international climate models surveyed by the Bureau of Meteorology expect the negative IOD event to persist until November, with all but one model expecting a return to neutral conditions in December.

National Climate Outlook

These climate outlooks are generated by ACCESS–S (Australian Community Climate Earth-System Simulator–Seasonal). ACCESS–S is the Bureau of Meteorology's dynamical (physics-based) weather and climate model used for monthly, seasonal and longer-lead climate outlooks.

For further information, go to http://www.bom.gov.au/climate/ahead/about/

The Bureau of Meteorology’s latest rainfall outlook indicated wetter than average conditions are expected for much of eastern and central Australia during August. The wetter than average conditions expected for most cropping regions reaffirms the positive production outlook for Australia’s 2021 winter cropping season. The ACCESS-S climate model suggests there is close to a 65% chance of exceeding average September rainfall totals across much of Australia.

The outlook for September 2021 indicates that there is a 75% chance of rainfall totals between 10 and 100 millimetres across parts of eastern, south-western and far southern Australia. Rainfall totals in excess of 100 millimetres are expected across alpine regions of New South Wales and Victoria, and western Tasmania.

Across cropping regions there is a 75% chance of rainfall totals of between 5 and 10 millimetres in parts of northern Queensland. There is a 75% chance of rainfall totals between 10 and 50 millimetres for New South Wales, southern Queensland, Victoria, South Australia and Western Australia. This expected rainfall for September is likely to be sufficient to support the ongoing growth, and eventual yield development, of winter crops in most regions.

©Commonwealth of Australia 2021, Australian Bureau of Meteorology - Issued: 05/08/2021

The rainfall outlook for spring 2021 (September to November) suggests there is a greater than 70% chance of exceeding average rainfall across much of New South Wales, Queensland, Victoria, South Australia and the Northern Territory. There is an increased chance of below average rainfall across the north and part of south-west Western Australia and western Tasmania during spring 2021 (Bureau of Meteorology ‘National Climate Outlook’, 5 August 2021).

Bureau of Meteorology rainfall outlooks for spring have greater than 55% past accuracy across most of Australia. Outlook accuracy is greater than 65% across much of New South Wales, Victoria, Queensland, South Australia and much of the Northern Territory. On the other hand, there is low past accuracy for large areas of northern and central Western Australia.

Chance of exceeding the median rainfall September to November 2021

©Commonwealth of Australia 2021, Australian Bureau of Meteorology - Issued: 05/08/2021

The outlook for spring 2021 suggests there is a 75% chance of rainfall totals between 50 and 200 millimetres across much of New South Wales, Victoria, southern and eastern Queensland, the south of Southern Australia, the far south-west and north-east of Western Australia, Tasmania, and large areas of the Northern Territory. Rainfall totals in excess of 300 millimetres are likely across parts of eastern New South Wales and Victoria, and western Tasmania.

Across cropping regions, there is a 75% chance of receiving between 50 and 200 millimetres in New South Wales, Victoria, South Australia, Queensland and southern Western Australia. Totals of less than 50 millimetres are expected across remaining cropping regions in Western Australia.

These rainfall totals are below average for this three-month period across most Western Australian cropping regions, and slightly above average for cropping regions of New South Wales. Above average soil moisture levels in Western Australia, and the probability of average or better in-season rainfall in September and October, will assist with maintaining or improving current yield potential in most winter cropping regions.

The temperature outlook for September to November 2021 indicates that maximum temperatures across most of Australia are likely to be close to the 1990-2012 average (- 1°C to 1°C). Minimum temperatures are expected to be slightly above average for much of Northern Australia (Bureau of Meteorology ‘National Climate Outlook’, 5 August 2021).

Rainfall forecast for the next eight days

The influence of slow-moving high-pressure systems is likely to bring clear skies and dry conditions across much of Australia over the next eight days. Rainfall is likely to be limited to west facing southern coastlines and onshore flow will bring showers to isolated areas of Australia’s eastern coast.

Rainfall totals of between 5 and 15 millimetres are forecast for isolated parts of southern and north-eastern New South Wales, north-eastern Queensland, as well as parts of Victoria, the south-east of South Australia, south-west Western Australia and Tasmania. Larger falls of between 15 and 100 millimetres are forecast for western Tasmania and parts of north-eastern Queensland.

Little to no rainfall is forecast for most of Australia’s cropping regions during the next 8-days.These dry conditions across most cropping regions will allow for drying of saturated soil profiles in some areas, reducing the impact of waterlogging and associated water-damage. Crop development is expected to progress unimpeded with high levels of plant available moisture provided by previous heavy falls. With the continuation of dry conditions from last week, growers will be able to gain unimpeded access to paddocks for top-dressing of fertilizer and for the allocation of pest and disease control programs in the coming week.
