Records are expected to tumble across Queensland this week as a heatwave ramps up throughout parts of the state.

Birdsville has already set a new record for the hottest minimum temperature, only dropping to 33 degrees overnight.

The town is predicted to reach a maximum temperature of 47 degrees today, having already hit 42 just before 10:30am. Elsewhere, Goondiwindi will hit 45 degrees today and 46 tomorrow. While Cunnamulla is predicted to reach 45.

The hot conditions are expected to last throughout the rest of the week throughout the state, with a stagnant air mass causing the hot conditions to stick around through southern Queensland.

Brisbane, however, will escape the brunt of the heatwave, with temperatures in the low-to-mid 30s predicted for the rest of the week.

The heatwave comes after Sydney sweltered through its third hottest ever pair of days and the hottest pair of spring days on record.
