Rainfall

The NSW statewide average rainfall for August was 10.2 mm which is very much below the historical average1 of 39.8 mm. This is 8th driest August on record and 6th consecutive August with below average rainfall for NSW. Large parts of the state were very much below their August average rainfall, with only some areas (south of the ACT and far western NSW) recording average falls for the month. A few locations recorded their lowest rainfall on record during August (see record tables below). The dry conditions were due to the lack of moisture and a series of high pressure systems ridging over the state, resulting in persistent clear skies. These high pressure systems blocked any frontal system which may have otherwise brought rainfall during the month.

The Murray Darling Basin recorded a basin wide average of 14.2 mm, which is very much below the historical average1 of 39.3 mm.

Some sites had their lowest total August rainfall on record.

See a map of total rainfall. See a map of rainfall deciles.

Temperature

NSW experienced an exceptionally warm August ranking as the 3rd warmest August on record. The average for the month was 20.4°C, which is 3.2°C above the historical average1. The monthly average was strongly influenced by record breaking temperatures between the 23rd and 25th of the month. Many locations in northern NSW broke their August and winter records, with 37.8°C recorded at Mungindi on the 25th of the month breaking the record for highest temperature ever recorded anywhere in NSW during August and winter (see record tables below). The temperatures experienced were equivalent to warm summer day time temperatures. The exceptionally warm conditions were caused by the lack of cold outbreaks bringing cool air from the Southern Ocean northward, as well as lack of moisture and consequent persistent clear skies. A series of high pressure systems ridging over NSW resulted in warm temperatures recorded throughout the rest of August.

Average minimum temperatures were also very much above average. The statewide average minimum temperature for August was 5.9°C, which is 1.2 °C above the historical average1 of 4.7°C. This ranks as the 5th warmest August on record for average minimum temperatures. Warm northwesterly winds and warm sea surface temperatures were partly responsible for keeping overnight temperatures well above average throughout August.

Some sites had their highest August temperature on record.

Some sites had their highest August mean daily maximum temperature on record.

See a map of mean maximum temperatures. See a map of maximum temperature anomalies.

Some sites had their lowest August temperature on record.

Some sites had their warmest August night (highest daily minimum temperature) on record.

Some sites had their highest August mean daily minimum temperature on record.

See a map of mean minimum temperatures. See a map of minimum temperature anomalies.

Other phenomena

Exceptionally high temperatures were recorded across northern NSW between the 23rd to the 25th of the month resulting in many long term temperature records being broken (see record tables below). Other locations also broke their all time records including Moree, Byron Bay and Lismore. For more information please see the Bureau's Special Climate Statement issued 26th August 2009. Strong winds were also recorded in southern parts of the state during the same period with the highest wind gust of 126 km/h recorded at Cabramurra SMHEA AWS on the 25th of August with many other locations recording wind gusts of over 100 km/h.

Notes

This statement has been prepared based on information available at 10 am on Tuesday 1 September 2009. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

A note about deciles: Deciles are used to give an element (in this case rainfall or temperature) a ranking. Deciles are calculated by arranging the totals in ascending order (from lowest to highest) then splitting them into 10 equal groups (thus the groups are called deciles). The first group would be in decile range one, the second group in decile range two, etc up to the highest annual totals (highest 10 per cent) being in decile range 10.

1Averages: Averages are based on the period 1961 to 1990 which is a convention of the World Meteorological Organisation

Normals are long-term averages based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 20 years of record for temperature and less than 30 years of record for rainfall, as they cannot then be calculated reliably.
