Sydney Coastal Waters

Broken Bay to Port Hacking
Wind
Southerly 15 to 20 knots.
Seas
1 to 1.5 metres, increasing to 1.5 to 2 metres offshore.
1st Swell
Southerly 3 to 4 metres.
Weather
Partly cloudy.
Caution
Large and powerful surf conditions for the rest of the day 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 near Victoria extends a ridge over the coastal waters. From Monday, winds should gradually turn southeasterly as the high moves gradually eastwards over the Tasman Sea.
