Parts of the east coast are set to swelter through extreme temperatures this week due to a post-summer heatwave.

The March record stands at 37.9C degrees for Brisbane and 38C for Ipswich.
The forecast has prompted the Bureau of Meteorology to issue a severe heatwave warning for south Queensland.

'A trough off the south-eastern Queensland coast has been quite persistent in its location, so the northerly winds will bring warm air to the region over the next few days,' Bureau of Meteorology forecaster Michael Gray told Daily Mail Australia.
'It will start to cool down after Tuesday but the warm weather will be around until next weekend with temperatures in the mid 30s for those away for the coast. Central Queensland will also see above average temperatures right through to the end of the week.'
Temperatures on the Gold Coast will remain in the 30s for much of the week.
'We're expecting big crowds,' Lachlan Weston from Surf Life Saving Queensland told the ABC.
Mr Gray said the warm weather isn't unusual for this time of the year in south-east Queensland.
'It's only been a few weeks since summer has ended,' he told Daily Mail Australia.

'We're in the middle of the transition from summer into the cooler months, so there will be a few more weeks of warm weather.'
Mr Gray had this advice for residents in south-east Queensland over the coming days.
'Stay inside in the air conditioning, keep water bottles full and don't go outside in the hottest part of the day between 10am and 3pm,' he said.
