The Bureau of Meteorology issued a weather warning on Sunday afternoon along the state's coast, as "vigorous" and "damaging" southerly winds will sweep up the coast from Monday afternoon.

The winds should prevent overnight temperatures from getting too low, but they will involve a "significant wind chill", particularly on Tuesday.

"Tuesday morning, about the time people are commuting to work, will see the strongest [of the winds] start to come moving through. But it does look to be pretty gusty through the whole day," Mr Hough said.

The heavy winds will start to ease on Wednesday afternoon, Weatherzone said.

But, as the state enters its first week of water restrictions, rainfall is likely to remain "mainly coastal", with less than five millimetres expected west of the ranges on Tuesday, Mr Hough said.

"On Wednesday, there still could be a fair amount of heavier rain around, but it will push even more coastal, more confined," he said.

The State Emergency Service advised on Sunday evening that people should move vehicles under cover or away from trees, and secure any loose items on balconies or in gardens.

The bureau has warned that "people should stay well away from the surf", with "large and powerful" waves in excess of five metres expected along the coast from Monday afternoon.

Heavy surf will batter the southern coast on Monday afternoon, before hitting beaches further north on Tuesday, the bureau said.

Activities such as swimming, rock fishing and surfing would be "hazardous" in the surf and wind conditions, it warned.

South-facing beaches would be most affected, but damage and erosion could occur across the coastline.

A marine wind warnining is in place across the coast until Monday evening, with strong winds expected from Byron to the Batemans coast, and gale winds expected at the Eden Coast area.
