IT MAY only be the second month of spring but Warwick will get a taste of summer as a heatwave hits the Rose City tomorrow.

Maximum temperatures will reach a top of 31 degrees tomorrow - five degrees above the October average - and remain in the low 30s until Thursday when daytime temperatures will drop back to the mid 20s.

Acting officer in charge of Warwick Ambulance Station Jamie Taylor said there was a greater demand for ambulance services in hot weather and urged residents to stay cool.

"If you don't take necessary precautions in high temperatures, there's a good chance you will be struck down with heat-related illness," Mr Taylor said.

"Symptoms can include fainting, nausea and vomiting, headaches and dizziness, disorientation or drowsiness.

"Drink plenty of water and avoid alcohol and coffee which can be dehydrating.

"Stay out of the sun between 11am and 3pm, and apply sunscreen, wear a hat and stay in the shade."

Area Director for the Queensland Rural Fire Service Tim Chittenden said it was important for property owners to be vigilant as the heat turned up the risk of bushfires.

"We are seeing an increase in fire danger over the next five days," Mr Chittenden said.

"We want to make sure people have their properties prepared and have a current bushfire survival plan." Meteorologist Nicholas Shera said much of south-east Queensland would feel the heat as an upper ridge moved north east from New South Wales.

"Having a warm spell last for a few days is unusual but these temperatures aren't entirely out of the ordinary for this time of year."
