Weekly update - 6 July 2017
- During the week ending 5 July 2017 rainfall totals exceeding 25 millimetres were recorded in south-western Western Australia, southern parts of South Australia, the Victorian Alps, north-eastern New South Wales, south-eastern and north-eastern Queensland, and western Tasmania.
- For the week ending 4 July 2017 maximum temperatures were generally close to average over much of the country, except in Queensland (2°C to 6°C above average) and central Western Australia (2°C to 4°C below average).
- Rainfall for June 2017 was below average across much of northern and southern Australia. Nationally, it was the second-driest June on record, with rainfall 62 per cent below average.
- Rainfall across southern Australia during June 2017 was well below average. This was largely the result of a series of stable high pressure systems blocking frontal systems that typically bring rain to southern Australia at this time of year.
- Upper layer soil moisture for June 2017 was extremely low across much of Australia. The main exceptions were in isolated parts of central Western Australia and eastern New South Wales for which soil moisture was well above average.
- The forecast for the next eight days indicates that rainfall totals between 10 and 50 millimetres are expected in central Queensland, alpine areas of Victoria, south-eastern South Australia, south-western Western Australia and western Tasmania. Rainfall is forecast to exceed 50 millimetres in central parts of the Northern Territory.
- Water storage levels in the Murray–Darling Basin (MDB) increased during the week ending 6 July 2017 by 118 gigalitres (GL) to 15,658 GL and are at 69 per cent of total capacity. This is 29 percentage points or 6,497 GL more than at the same time last year.
- Allocation prices in the southern Murray–Darling Basin steadily increased in the final weeks of the water year and closed at around $46 per megalitre. This likely reflected reports of dry conditions in water determination outlooks for Victorian and New South Wales valleys.
- Allocation markets remain closed in South Australia and Victoria, however appear to be converging at around $100 per megalitre in both the NSW Murray and Murrumbidgee areas.
- On 7 July the Australian Bureau of Statistics (ABS) will release the results of the 2016 Agricultural Census. The scope for the Census has changed compared with previous years. The minimum farm size, as determined by the value of agricultural operations, has been increased from $5,000 and over to $40,000 and over. This has reduced the number of operations surveyed compared with previous ABS rural environment and agricultural collections.
Rainfall this week
During the week ending 5 July 2017 widespread rainfall was recorded across eastern and southern Australia. Rainfall totals exceeding 25 millimetres were recorded in south-western Western Australia, southern parts of South Australia, and the Victorian Alps. Similar totals were recorded in north-eastern New South Wales, southern and north-eastern Queensland, and western Tasmania. The highest recorded weekly total was 168 millimetres at Topaz Alert, near Cairns in Queensland.
The rainfall analyses and associated maps utilise data contained in the Bureau of Meteorology climate database, the Australian Data Archive for Meteorology (ADAM). The analyses are initially produced automatically from real-time data with limited quality control. They are intended to provide a general overview of rainfall across Australia as quickly as possible after the observations are received.For further information go to Weekly Rainfall Update

Temperature anomalies this week
During the week ending 4 July 2017 maximum temperatures were generally close to average over much of the country, except in Queensland (2°C to 6°C above average) and central Western Australia (2°C to 4°C below average). Minimum temperatures were 2°C to 8°C above average across most of Queensland and northern parts of the Northern Territory, and 2°C to 6°C below average in southern Western Australia, south-eastern New South Wales, the Australian Capital Territory, Victoria and Tasmania. For the remainder of Australia minimum temperatures were close to average.

Note: Spatial temperature analyses are based on historical weekly temperature data provided by the Bureau of Meteorology. These temperature anomaly maps show the departure of the maximum and minimum temperatures from their long-term averages. Temperature anomalies are calculated using high-resolution gridded datasets from 1911 onwards. For further information go to Daily maximum temperature for Australia.
Rainfall for June 2017 was below average across northern and southern Australia. Nationally, it was the second-driest June on record, with rainfall 62 per cent below average. Parts of western and south-eastern Australia were particularly dry, with severe rainfall deficiencies present in Western Australia, South Australia, Victoria, southern New South Wales and eastern Tasmania. The only areas to record significantly above average rainfall were isolated parts of central Western Australia, pastoral districts of South Australia, and north-eastern New South Wales.
In cropping regions, June rainfall was severely deficient in South Australia, Victoria, central and southern New South Wales, and most of Western Australia. It ranged from average to below average in northern New South Wales, Queensland and central parts of Western Australia. These rainfall deficiencies are likely to increase moisture stress for winter crops, particularly in areas where temperatures have been above average for this time of year.
Rainfall percentiles for June 2017

Note: Spatial rainfall percentile analyses are based on historical monthly rainfall data provided by the Bureau of Meteorology. These rainfall percentile maps show how rainfall recorded during that given time period compared with the rainfall recorded for that same period during the entire historical record (1900 to present). Rainfall percentiles are a way of providing an indication of the spread of data in a data set. To calculate percentiles, the entire rainfall record at a certain point is divided into one hundred equal parts. The 5th percentile for June 2017 means that only five per cent of all Junes in the historical record have recorded a rainfall total that is at or below the rainfall recorded during June 2017. Dark blue areas on the maps are those areas that were wetter than the same time of year during the entire historical record, and dark red areas are drier.

Rainfall across much of southern Australia during June 2017 was well below average. This was largely the result of a series of stable high pressure systems blocking frontal systems that typically bring rain to southern Australia at this time of year. This is illustrated by the mean sea-level pressure (MSLP) anomaly map, which shows higher than average MSLP over much of southern Australia for June.
Other climate influences contributing to below average rainfall across Australia include a southward shift of the sub-tropical ridge over Australia, and a positive Southern Annular Mode (SAM). When SAM is positive at this time of year, the global belt of high pressure in the mid latitudes of the southern hemisphere shifts southwards, pushing cold fronts and moisture to the south of Australia.

Recent soil moisture percentiles
The maps below show the levels of modelled upper layer soil moisture (0 to 10 centimetres) and lower layer soil moisture (10 centimetres to 1 metre) during June 2017. These maps show how modelled soil conditions during June 2017 compare with June conditions modelled over the 105 year reference period (1911 to 2015). Dark blue areas on the maps are those that were much wetter in June 2017 than during the same period over the reference period. The dark red areas were much drier than during the reference period. These data are from the Australian Water Resources Assessment Landscape model (AWRA-L version 5.0), which was developed through the Water Information Research and Development Alliance (WIRADA) initiative. WIRADA is a collaborative project between the BoM and the CSIRO.
The bulk of plant roots occur in the top 20 centimetres of the soil profile. Soil moisture in the upper layer of the soil profile is therefore the most appropriate indicator of the availability of water, particularly for germinating plants. The lower layer soil moisture is a larger, deeper store that is slower to respond to rainfall and tends to reflect accumulated rainfall events over longer time periods.
Relative upper layer soil moisture for June 2017 was extremely low across much of Australia. The main exceptions were in isolated parts of central Western Australia and eastern New South Wales for which soil moisture was well above average. In cropping regions upper layer soil moisture was predominantly extremely low in all states. The pattern of relative upper layer soil moisture reflects June 2017 rainfall.

Relative lower layer soil moisture for June 2017 was well below average to extremely low across much of western and southern Western Australia, and southern parts of South Australia. Similar soil moisture levels were modelled for parts of eastern Victoria, central New South Wales, central Queensland and central parts of the Northern Territory. Lower layer soil moisture was well above average to extremely high in parts of central Western Australia, central South Australia, north-eastern Queensland and across the Top End.

Rainfall forecast for the next 8 days
The forecast for the next eight days indicates that rainfall is mainly expected across central Australia and parts of south-western and southern Australia. Totals between 10 and 100 millimetres are expected in central parts of the Northern Territory. Totals between 10 and 50 millimetres are forecast for central Queensland, alpine areas of Victoria, south-eastern South Australia and south-western Western Australia. Similar totals are expected in western Tasmania.

State water storages in the Murray-Darling Basin (NSW, Victoria and Queensland)
Although inflows in the last six months have been relatively low across the Murray-Darling Basin, opening allocations have been influenced by relatively high storage volumes.
Carryover volumes in New South Wales and Victorian systems appear high, however some carryover will not be immediately available to irrigators. Particularly, Victorian systems are not likely to allow access to carryover in the near-term through a low-risk of spill announcement. South Australia did not grant carryover to irrigators in 2016–17.

Allocation prices in the southern Murray–Darling Basin steadily increased in the final weeks of the water year and closed around $46 per megalitre. This likely reflected reports of dry conditions in water determination outlooks for Victorian and New South Wales valleys.
Allocation markets remain closed in Victoria and South Australia, with limited trade commencing in some New South Wales catchments.
The market appears to be converging at around $100 per megalitre in both the NSW Murray and Murrumbidgee areas, however there is insufficient trade to accurately report on opening prices.Trade from the Murrumbidgee to the southern connected system remains closed.

2016 Agricultural Census
On 7 July at 11.30am the Australian Bureau of Statistics (ABS) will be releasing data from the 2016 Agricultural Census.
The scope for the 2015–16 Agricultural Census is different to previous ABS rural environment and agricultural collections. The minimum farm size, as determined by the estimated value of agricultural operations (EVAO), has been increased from $5,000 and over to $40,000 and over. This change has reduced the number of small agricultural operations surveyed.
As a result, estimates from the 2015–16 Agricultural Census will not be directly comparable to previous published Agricultural Censuses or annual survey outputs. The ABS has produced a set of estimates from a number of rural environment and agricultural commodity collections from 2010–11 to 2014–15 using the new EVAO of $40,000 and over.
Estimates for 2014–15 using this new scope at national state/territory and sub-state levels can be found here:
- 7121.0 –Agricultural Commodities, Australia, 2014–15
- 7503.0 – Value of Agricultural Commodities Produced, Australia, 2014–15
- 4618.0 – Water use on Australian Farms, 2014–15
- 4627.0 - Land Management Practices and Farming, Australia, 2014–15
