View the current warnings for New South Wales

Forecast issued at 4:10 am EST on Thursday 25 September 2025.

Weather Situation

Westerly winds will dominate over the next few days as a high pressure system currently centred over the Bight slowly drifts east and over the north of the state, and a series of cold fronts brush the far south of the state. Brief incursions of southerly winds are likely over far southern coastal waters as the cold fronts pass to the south of the state. The high will drift into the Tasman Sea over the weekend, allowing onshore winds to return to most coastal waters from Sunday.
