The surf will be big but the skies will be blue over the long weekend, giving the Easter Bunny great conditions to hide his treats across the Illawarra.
According to the Bureau of Meteorology, patchy fog will give way to a mostly sunny sky on Good Friday, with temperatures in the low to mid 20s.
Easter Saturday and Sunday should be sunny, with top temperatures of about 21 degrees on both days. Monday will be partly cloudy.
However, Roads and Maritime Services has warned boaters to be wary on the water after forecasts of dangerous surf conditions along the NSW coast.
The RMS has advised skippers to be on high alert, to check forecasts, ensure everyone wears a lifejacket, and to log on and off with a Marine Rescue NSW marine radio base for every trip.
Likewise, rock fishers should check weather forecasts to determine if it is safe.
Moorings should be secure to prevent damage during strong winds.
