Western Australia in summer 2006−07

A hot summer

For Western Australia as a whole, summer 2006−07 was the 7th hottest. The mean maximum temperature and mean minimum temperature were 0.91°C and 0.59°C above the respective standard long term average (1961−1990).

The statewide rainfall total was near average despite areas in the far north Kimberley and large parts of the Pilbara and west Gascoyne experiencing below to very much below average rainfall due to a poor monsoon season. Parts of the Southeast Coastal, Eucla and Goldfields districts had very much above average rainfall due to the exceptional downpour from the "once in a generation"storm in January.

Some extremes and records for individual locations in WA are tabulated below.

Notes

This statement has been prepared based on information available at 2 pm on Thursday 1 March 2007. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Normals are long-term means 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 30 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of "normal" rain.
