Ulladulla and Nowra have had four straight days of maximums between 20 and 24 degrees from June 9 to June 12.

Nowra peaked at 23.8 degrees about 2pm on Wednesday while Ulladulla reached 22.5 about 3pm.

The uncanny warm winter days are a stark difference to last June where temperatures hovered around the 15 to 17 degree mark.

Minimum temperatures have been about the same in June of the past two years according to the Nowra Ran Air Station weather station with temperatures between 6 and 9.2 degrees.

Meanwhile Ulladulla has been slightly up with a minimum of 13.5 and 13.2 degrees on June 9 and 11. Ulladulla's area weather station only recorded one minimum above 13 degrees in June last year.

According to Weatherzone, southern Shoalhaven residents can expect temperatures between 11 and 18 degrees over the next week, with possible showers from Sunday, June 16 to Wednesday, June 19.

Northern Shoalhaven residents can expect similar temperatures at night with minimums between 7 and 8 degrees while the maximum is predicted to drop below 20 degrees from Friday.

The Bureau of Meteorology's winter climate outlook, issued May 30, suggests a drier than average winter is likely for much of the eastern and southern parts of Australia with daytime temperatures likely to be warmer than average.

Michele Thompson, visiting from Sydney, says she's a little bit selfish, recognising the warmer weather makes it easier to swim at the Ulladulla Sea Pool.

"However, I'm well aware we do need rain," she said.
