View the current warnings for New South Wales

Forecast issued at 10:00 pm EST on Wednesday 8 July 2026.

Weather Situation

A strong high pressure system over Tasmania and a low pressure system moving over New Zealand will continue to drive fresh southerly winds and hazardous surf conditions to the coastal areas today. Then, the high will enter the Tasman Sea on Thursday, maintaining a ridge over the southern half of the coast while a weak trough develops off the northern half of the coast. Winds will gradually ease before turning northerly and freshening during the weekend as the ridge extends over the northern coastal waters.
