ADIOS, La Nina, you certainly made your presence known in the Southern Downs of late but, thankfully, we can now wave goodbye.

The main cause behind the county's flood-ravaged summers has officially left the building which, ultimately, means drier weather ahead but Bureau of Metrology acting region climate services manager Tamika Tihema warns against becoming too complacent.

"We are heading into a neutral state which should stick around for one to three months," Ms Tihema said.

"Keep in mind it is thunderstorm season, so we're not ruling out any extreme rainfall.

"The odds of exceeding average rainfall over the three months of autumn in the region is actually 75-80% likely," she said.

Ms Tihema said Warwick could expect cooler days and warmer nights in the lead-up to colder months.

"Anyone who requires frost or cool nights to grow fruit needs to look at these forecasts and have a plan in place because we will possibly have warmer nights," she said.

After La Nina decided to stick around for two back-to-back events, Australia experienced its wettest two-year period on record.

Coming into the cooler months, Ms Tihema predicted less rain for the region and more sunshine - typical of a drier season.

BOM forecaster Peter Otto said Warwick should expect sunny days for the rest of the week.

"It will be fine outside for the next few days, with the slightest chance of a shower, but mainly fine until Friday," Mr Otto said.

"Conditions should be keeping fine over the weekend."

Today is expected to reach a top of 26 degrees, with 27 degrees on Friday and Saturday and 28 degrees on Sunday.

One Warwick girl, thrilled to hear the sun was sticking around, said this was her favourite type of weather.

"I like playing in the park in the sun," Aleisha Winsor-bennet, 4, said.

She said she also enjoyed jumping on the trampoline when the sun was out and hoped it would stick around for the rest of the month.
