Weather Situation
Onshore northeast to southeasterly winds along the coast will gradually turn north to northeasterly and continue freshening mid to late this week as a high over the Tasman Sea strengthens while extending a ridge to the coastal waters. Then, a cold front and its associated trough looks set to cross the coastal areas during the weekend, bringing a fresh to strong southerly wind change in their wake.
