Southerly 3 metres inshore, increasing to 3 to 4 metres offshore south of Point Perpendicular.
Weather
Partly cloudy.
Caution
Large and powerful surf conditions in the evening are expected to be hazardous for coastal activities such as crossing bars by boat and rock fishing.
Weather Situation
Southerly winds will be maintained during the weekend as a high pressure system over Victoria extends a ridge over the coastal waters and enters the southern Tasman Sea by Sunday. From Monday, winds should gradually turn southeasterly as the ridge persists through to mid-week.
