Key issues
- During the week ending 2 May 2018 little to no rainfall was recorded across much of the country. Rainfall was mainly restricted to parts of the mainland east coast and western Tasmania.
- April 2018 was Australia’s second warmest April on record for the country as a whole; the national monthly mean temperature was 2.38 °C above average, just 0.28 °C behind the record set in 2005. The mean monthly maximum temperature for Australia as a whole was the warmest on record at 3.17 °C.
- For Australia as a whole, rainfall during April 2018 was very much below average, coming in at the eighth driest on record and the driest April since 1997. Below average rainfall was recorded across large parts of southern Australia, with areas of severe deficiency in south-eastern and south-western New South Wales, eastern Victoria, and across isolated areas of South Australia and southern Western Australia. In contrast, well above average to extremely high rainfall was observed across parts of coastal and south-western Queensland and isolated area of northern Australia.
- Relative upper layer soil moisture for April 2018 was extremely low across large areas of southern Australia. In contrast, it was well above average across parts of coastal and south-western Queensland and isolated area of northern Australia.
- Relative lower layer soil moisture for April 2018 was extremely low in south-eastern Australia, and far western Western Australia. It was extremely high in northern and south-western Queensland, south-eastern parts of the Northern Territory, and south-eastern parts of Western Australia.
- During the next eight days rainfall is mainly expected in south-eastern Australia and western Tasmania.
- Water storage levels in the Murray–Darling Basin (MDB) decreased during the week ending 3 May 2018 by 46 gigalitres (GL) to 11,077 GL and are at 49 per cent of total capacity. This is 18 percentage points or 4043 GL less than at the same time last year
- Allocation prices in the southern Murray–Darling Basin increased in the week ending 3 May 2018 to $154 per ML. This is an increase of $12 from the same time last week.

Rainfall this week
During the week ending 2 May 2018 little to no rainfall was recorded across much of the country. Rainfall was mainly restricted to parts of the mainland east coast and western Tasmania. Rainfall totals between 15 and 50 millimetres were recorded along coastal New South Wales and isolated areas of coastal Queensland. Similar totals were recorded in western Tasmania. The highest recorded weekly total was 216 millimetres at Barrington Tops, north of Newcastle.

Monthly temperatures
April 2018 was Australia’s second warmest April on record for the country as a whole; the national monthly mean temperature was 2.38 °C above average, just 0.28 °C behind the record set in 2005. April was warmer than average for nearly all of Australia, and particularly warm in terms of maximum temperatures. The mean monthly maximum temperature for Australia as a whole was the warmest on record at 3.17 °C. Although overnight temperatures were not as extreme, the national mean minimum temperature was still the fourth warmest on record at 1.59 °C above average for April.

Monthly rainfall
For Australia as a whole, rainfall during April 2018 was very much below average, coming in at the eighth driest on record and the driest April since 1997. However, there was some degree of variability across the country. Well above average to extremely high rainfall was observed across parts of coastal and south-western Queensland and isolated area of northern Australia. Below average rainfall was recorded across large parts of southern Australia, with areas of severe deficiency in south eastern and south-western New South Wales, eastern Victoria, and across isolated areas of South Australia and southern Western Australia.
In cropping regions, April 2018 rainfall was close to average in Queensland and northern New South Wales. It was well below average in central and southern New South Wales, Victoria, and parts of South Australia and Western Australia.

Monthly soil moisture
Relative upper layer soil moisture for April 2018 was extremely low across large areas of southern Australia. In contrast, it was well above average across parts of coastal and south-western Queensland and isolated area of northern Australia. Upper layer soil moisture was close to average across the remainder of the country. The pattern of relative upper layer soil moisture largely reflects April 2018 rainfall.
Upper layer soil moisture was close to average across most cropping regions in northern New South Wales, central Western Australia and northern New South Wales. In contrast, it was well below average to extremely low across central and southern New South Wales, Victoria and parts of South Australia and Western Australia.

Note: This map shows the levels of modelled upper layer soil moisture (0 to 10 centimetres) during April 2018. This map shows how modelled soil conditions during April 2018 compare with April conditions modelled over the reference period (1911 to 2015). Dark blue areas on the maps were much wetter in April 2018 than during the same period over the reference period. The dark red areas were much drier than during the reference period. 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 lower layer soil moisture for April 2018 was extremely low in south-eastern Australia, and far western Western Australia. It was extremely high in northern and south-western Queensland, south-eastern parts of the Northern Territory, and south-eastern parts of Western Australia.
In cropping regions, lower layer soil moisture was generally average in Queensland and eastern parts of Western Australia. It was extremely low in central and southern parts of New South Wales, Victoria South Australia and western cropping areas in Western Australia.

Rainfall forecast for the next 8 days
During the next eight days, rainfall is mainly expected in south-eastern Australia and western Tasmania. A strong low-pressure system is expected to move to the south of the country and an associated cold front that is moving from South Australia to the east is predicted to triggering areas of heavy rain, gusty winds and thunderstorms.
Falls of between 10 and 50 millimetres are expected across southern agricultural regions of South Australia, south-western Victoria and alpine regions of New South Wales and Victoria. Higher totals (exceeding 50 millimetres) are forecast for western parts of Tasmania. Elsewhere, totals between 10 and 50 millimetres are forecast for isolated parts of south-eastern Queensland. Little to no rainfall is expected across the remainder of the country.
This rainfall forecast is produced from computer models. As it contains no input from weather forecasters, it is important to check local forecasts and warnings issued by the Bureau of Meteorology.
