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

View the current warnings for New South Wales

Forecast issued at 4:05 pm EDT on Tuesday 27 October 2020.

Weather Situation

A strong high pressure system south of Tasmania is slowly moving east, while a low pressure system over the Tasman Sea extends a trough towards the Queensland coast. This pattern will maintain south to southeasterly winds over Sydney waters for the next day or two. On Thursday, the coastal trough may deepen and strengthen southerly winds as a transient low pressure system forms and moves away to the east. After this, winds are expected to turn east to northeasterly and increase as a new trough develops over inland New South Wales.
