Rainfall

February rainfall was below to very much below average in the west and northwest of WA, but near average for large parts of central and eastern WA. Only small areas of eastern and southern WA saw above average February rainfall, including parts of the South and Southeast Coastal districts. Averaged across the state, the rainfall for February 2010 was in the below average range (see February rainfall decile map).

A very quiet monsoon season in the north of the state saw no tropical cyclones in the WA region for the month of February, an unusual occurrence. The west Kimberley was particularly dry as a result and Broome recorded its driest February on record.

Some sites had their lowest total February rainfall on record.

February 2010 ranked the third warmest February on record in terms of mean temperature. The mean temperature for WA was 29.8°C, 1.7°C above the long term average of 28.1°C.

Maximum temperature

In contrast, parts of the coastal Pilbara and Gascoyne saw below average mean maxima, up to 4°C below normal near the north Gascoyne coast (see February maximum temperature anomaly map). When averaged over the whole state, it was the 4th hottest February on record.

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

Minimum temperature

Mean minimum temperatures across WA showed a similar pattern to that of mean maximum temperatures. Above to very much above average mean minimum temperatures were recorded in most of WA, with up to 4°C above normal minima in the parts of the southern Pilbara and northern Gascoyne (see February minimum temperature anomaly map). Only parts of the coastal west Pilbara recorded below average mean minima for February. When averaged over the whole state, it was the 4th hottest February on record in terms of mean minimum temperatures.
