THIS month has been a "scorcher" for Warwick, with the region simmering in the hottest average temperature in almost 10 years.

The maximum average for July was 18.4 degrees, compared to the 17.4 degrees at this time last year.

This year has been the hottest July since 2004, which recorded a "blazing" average of 18.8 degrees.

Combining the maximum average day and night temperatures, Warwick comes in at 12.2 degrees this month, which is the highest in 20 years.

Meteorologist Brett Dutschke said the warmer-than-average temperatures were due to a lack of cold fronts, which usually bring the cold Antarctic air during the winter.

"Warwick is usually influenced by the cold fronts coming from the west and the south, but they were generally weaker this year," he said.

"We've only had one intense cold front so far, usually there is three or four by this time."

Another factor was the warmer ocean temperatures around Australia, with Warwick and western regions missing out on a lot of rain that fell further east.

The region's average minimum temperature is 1.5 degrees higher than July 2012, coming in at 5.8 degrees.

The warmer temperatures for the area mean some fruit trees are budding early, which could have a big impact for farmers.

Mr Dutschke says the "heat wave" has happened a few times over the past 40 years, but this year will definitely be in the top five on record in Australia.

Most eastern areas of the country have been affected, including Brisbane, Sydney, Melbourne and Canberra, which have recorded their warmest July since the 1800s.

Back to Warwick, the outlook for August is looking to be quite a bit drier than average.

Warwick rainfall this July was 31mm on average - 8mm more than last year.

Average wind speed this month was 6.8kmh, compared to 7.5 kmh in June.

"We will probably be in a bit of a drying-out phase because this July was a bit wetter than normal," Mr Dutschke said.

"It looks like there will be a couple of stronger fronts coming through, which means there is a good chance of it getting frosty."

Overall, August daytime temperatures should be fairly close to average.

"There will be a few cold days thrown in, felt most in the mornings and evenings with a bit of chill."
