Mild Top End and cooler temperatures in the south  - Northern Territory in August 2008

Summary

Maximum and mininum temperatures were below average over most of the Territory during August 2008. Exceptions to this were a few patches in the Top End and central parts of the Territory where the temperatures were up to one degree above average. Unusal rainfall, mostly during the last weekend of the month, contributed to some rainfall records in the Alice Springs and Victoria districts.

Rainfall

The Top End and most of the Barkly district remained dry during August. The rest of the Territory received rainfall mostly during the last week of the month with some areas reporting about 25 mm totals for August. A trough over Western Australia, and the high pressure system over southern Australia during the last week of the month, contributed to the development of rain bearing weather conditions over the southern Northern Territory.

Some sites had their highest total August rainfall on record.

The wettest single day 20.6 mm at Jervois on the 31st, followed by 19.0 mm at Curtin Springs on the 30th, followed by 17.2 mm at Atula on the 31st.

Some sites had their highest August daily rainfall on record.

Maximum temperature

However, the daytime temperatures remained warmer than normal in the northwestern Top End including Darwin and the coastal areas of the Roper McArthur district.

Some sites had their highest August temperature on record.

Notes

This statement has been prepared based on information available at 10 am on Monday 1 September 2008. 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 the years 1800 to 2007. They are not shown for sites with less than 10 years of record in that time, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average ("normal") rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, normal in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of normal shows how much rain has fallen this time as a percentage of the long-term mean.
