RACQ has released data showing five rescues of Queensland children or dogs a day, from hot cars in the past year.

Spokeswomen Kirsty Clinton says its important for people to be vigilant in the summer months as temperatures in cars can rise by ten degrees in eight minutes, even if parked in the shade or with an open window.

The report comes as a heatwave breaks records across Queensland, continuing into the weekend, with Cooktown recording a scorching 43.9 degrees yesterday afternoon.
