Equal warmest August on record for Sydney

Press Release, Friday August 31, 2007 - 13:08 EST

Sydney has just experienced its equal warmest August on record, according to weatherzone.com.au.

The city had an average maximum temperature of 20 degrees, above the long-term normal of 18. In fact, on the 27th, the temperature hit 28 degrees, making it the warmest August day in 12 years.

The average minimum temperature was 12 degrees, well above the long-term normal of nine. This made it the warmest August in terms of overnight temperatures since records began in 1859. On the morning of the 30th, the temperature did not fall below 17 degrees, making it the mildest August night in five years.

When both daytime and overnight temperatures were combined, the average August temperature for Sydney came in at 16 degrees, well above the long-term normal of 13. This made it the equal warmest August since records began in 1859, tied with 1995.

"It has been a consistently warm month from beginning to end. Both daytime and night-time temperatures have been above average. If not for a brief cold spell at the start of the month, it would have exceeded 1995 as being the outright warmest August on record," weatherzone.com.au meteorologist Matt Pearce said.

Temperatures were above average right across New South Wales during August, especially by night. For example, Nobbys Head, near Newcastle, had an average minimum temperature of 12 degrees, its warmest for August in 143 years of records.

The northeastern third of the state picked up some very welcome rainfall during August. For example, Grafton received 189mm, its highest August total in 52 years of records.

Sydney recorded 152mm, significantly above the long-term normal of 81mm. This made it the wettest August since 2004.

Unfortunately, inland areas did not receive any significant rain at all. Albury’s total of 13mm was its lowest for August in 24 years of records.

"Northeastern New South Wales received a few days of heavy rain between the 19th and 21st thanks to an in-feed of moisture from the north. Unfortunately, because this moisture came in from the north, it completely bypassed the parched interior of the state," Pearce said.

"Temperatures are likely to remain above average across the state over the next few months, especially by night. Rainfall patterns look like remaining fairly close to normal, possibly favouring wetter-than-normal weather in the east due to a warming in the Coral and Tasman Seas," Pearce said.
