Please be aware
Wind and wave forecasts are averages. Wind gusts can be 40 per cent stronger than the forecast, and stronger still in squalls and thunderstorms. Maximum waves can be twice the forecast height.
Strong south to southeasterly winds and large powerful waves along the north coast are gradually easing as a low and a trough over the Coral Sea continue to weaken. Meanwhile, winds over the southern and central parts of the coast are turning northerly as a strong high pressure system over the Tasman Sea extends a ridge across much of the state. Then, a cold front crossing the state mid to late this week will bring a fresh to strong southwesterly wind change in its wake.
