Western Australia in June 2007
A dry and cold month

Summary

June 2007 was a dry month for WA as a whole. Large areas of the state received below to very much below average rainfall with some locations in the Southwest Land Division registering their driest June on record. In contrast, the north and east Kimberley saw above to very much above average rainfall due to unseasonable heavy falls from slow moving middle level cloud-bands in the second half of the month. Several northeast Kimberley locations recorded their highest June rainfall.

The statewide mean maximum temperature was the lowest since 1995 with an anomaly of −0.5°C, although west coast districts generally saw above temperature. Areas in the east Kimberley and northeast Interior were 3 to 5°C cooler than normal with some locations registering record low mean maximum temperatures for June. The mean minimum temperature across the state was 1°C below the long term (1961−1990) average, with most WA districts seeing below normal minimum temperatures on record.

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

Notes

This statement has been prepared based on information available at 10 am on Monday 2 July 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.
