Hot summer days do not come as a surprise for those living in South Australia's Riverland. 

But when three consecutive days in excess of 45 degrees Celsius were forecast as part of an extreme heatwave sweeping across the country, people took note.

At Renmark, temperatures hit 38C on Tuesday, 44C on Wednesday, and 47C on Thursday, with a top of 47 forecast today. 

For many, it was a case of simply getting through, while for others it was about making the most of existing holiday plans in the popular tourist region.

Mr Calvert said the sweltering weather was just part and parcel of living in the region.

"I mean, it's summer in the Riverland. You've got to expect a few hot days," he said.

"There's a river at one end and a pool at the other."

The caravan park was forced to rebuild after the devastating 2022–23 River Murray floods.

This year's hot weather shows a stark contrast at the campsite's popular pool compared to this time three years ago.
