New South WalesSynoptic Situation: A strong and slow-moving high pressure system near New Zealand extends a ridge towards New South Wales, and is bringing a gradual return to northeasterly winds to all coastal waters. Winds are forecast to increase today ahead of a cold front, which will bring a southerly change to the southern coast later Saturday and to central parts on Sunday before stalling. A second front will follow on Monday, pushing the change to the Queensland border by Tuesday.
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.
