A heatwave is set to send mercury in the south-east skyrocketing over the next few days, with temperatures averaging about eight to ten degrees hotter than usual.

Bureau of Meteorology meteorologist David Crock says places such as Ipswich, Gatton and the wider Lockyer Valley can expect temperatures to reach 40 degrees before easing on Wednesday.

The heatwave is expected to last three days, bringing a little bit of Summer into our Autumn, causing meteorologists to predict a number of record-breaking temperatures in March.
