Caution
Surf conditions for the rest of the day may be more powerful than they appear and are expected to be hazardous for coastal activities such as crossing bars by boat and rock fishing.
Weather Situation
A high pressure system over the Tasman Sea directs and east to northeasterly flow through the coastal waters. Winds will freshen and tend more north to northeasterly on Thursday and Friday as the high slips further to to the east. A cold front and trough will then enter the Tasman Sea, bring a southerly change which will gradually track northward through the weekend.
