The Weather Bureau has issued a severe weather warning for damaging surf hitting much of the NSW Coast on Sunday.
It says a trough of low pressure will move up the NSW coast overnight Saturday and on Sunday morning bringing fresh to strong southeasterly winds and driving very heavy surf from the southeast.
It might lead to localised damage and coastal erosion.
Significant wave heights greater than five metres and peak period around 12 to 15 seconds are expected to develop along the South Coast before dawn on Sunday then extend northwards.
Areas impacted include exposed south and southeast facing coasts of the South Coast, Illawarra, Sydney Metropolitan, and Hunter forecast districts, and the far south of the Mid North Coast forecast district.
Beach conditions in these areas could be dangerous and people should stay well away from the surf and surf exposed areas.
A separate Hazardous Surf warning is also current and expected to continue until Monday.
Locations which may be affected include Newcastle, Sydney, Wollongong, Batemans Bay, Eden, Moruya Heads, Narooma and Merimbula.
The State Emergency Service advises that people should stay vigilant and monitor conditions.
