Heatwave sees cancellation of Adelaide's Australia Day events but cricketers bat on

A week after the Tour Down Under had to be altered to accommodate extreme temperatures, Australia Day events are being cancelled in Adelaide as the city braces for another spell of hot weather.

Friday's forecast of 38 degrees Celsius has prompted several local councils to reschedule family and children's events, while wineries participating in the Adelaide Hills Crush Festival have cancelled about a third of 50 planned events.

The wine region celebration runs throughout the long weekend but will be suppressed by an even hotter 42C forecast for both Saturday and Sunday.

Kevin Knight, the Mayor of City of Tea Tree Gully, told ABC Radio Adelaide that its Australia Day ceremony would still be held on Friday, while a children's slip and slide event has been rescheduled.

The City of Charles Sturt Council postponed Friday's Movies Under The Stars event, while the City of West Torrens cancelled its All Together Now festival.

An Australia Day Family Picnic scheduled by the City of Salisbury has also been scrapped.

Bureau of Meteorology Senior Forecaster Tom Boeck said the hot weather was on track to arrive as expected, stating "the good news is there is a change expected to be developing Sunday night.

"It's a significant change in terms of dropping the temperature. We're looking at a maximum of just 24C on Monday, which will be a nice change."

People planning on attending events have been advised to keep checking if they're going ahead.

However, the Australia Day one-day international cricket match between Australia and England at the Adelaide Oval will go ahead.

Adelaide Oval Stadium Management Authority spokesperson Darren Chandler told the ABC "it's going to be hot, but it's summer sport and I'm sure people coming along will equip themselves accordingly.

"Everyone's got to be smart about it and find shade where they can. There's plenty of concourse areas people can retreat to in between overs."

Chandler advised that all the grandstands had been installed with fans, while St John Ambulance Service and Red Frogs volunteers would be in the crowd.

Chandler added "they are out and about in the crowd giving out free water, sunscreen, and are looking for people who might be in distress.

"Our staff are trained in that area as well.

"This is a day-night game as well, so half the game will be under lights."

England captain Joe Root was hospitalised with heat exhaustion having batted in high temperatures during the fifth Ashes Test in Sydney earlier this month.
