Sydney Enclosed Waters Forecast: Sydney Harbour, Pittwater and Botany Bay

View the current warnings for New South Wales

Forecast issued at 4:05 pm EDT on Monday 10 February 2025.

Weather Situation

A high pressure system over the southern Tasman Sea, together with a trough along the coast, are bringing onshore northeast to southeasterly winds along Sydney Waters. Winds will become northeasterly through the midweek as the trough weakens and the high moves to New Zealand, then the next cold front and its associated trough looks set to cross the coastal waters later in the week through the weekend, with a gusty southerly change in its wake.
