Taking advantage of the sun and the sand was army recruit Micro Steven, who came with his comrades Hanna Reeve and Samuel Cutts for an impromptu sunbathing session at Wagga beach.

"Today's actually pretty nice. The last couple of day have been super hot so we're taking the opportunity to get out and about," Mr Steven said.

"We work together, so we just had breakfast and decided to come here."

Kayaking enthusiast Jake Bourne made the most of the sunny weather by heading out onto the water, saying he had missed being able to get out and row during the months of lockdown.

He said the river levels made for good kayaking for this time of year, following a decent level of rainfall across the Murrumbidgee River.

"It's really good. The river's up, and it's fantastic," Mr Bourne said.

"The levels are always good. As the year gets on it gets lower and lower, but it's good right now."

The temperatures are expected to climb into the high 30s throughout the rest of the week in Wagga, hitting a peak maximum of 40 degrees on Saturday.

The unseasonably warm weather is caused by a "severe" heatwave washing across the state, with the heat only dissipating slightly on Monday next week.

The Bureau of Meteorology is predicting "extreme" UV ratings of 11 and above for Wagga over the next few days, and are recommending people wear sun protection at least through the hours of 8.30am to 5pm.
