Weather Situation for Sydney Enclosed Waters
A high pressure system over the southeastern Tasman Sea is extending a ridge towards eastern New South Wales maintaining a northeasterly airstream along Sydney coast, while a trough off the far south coast is slow moving and weakening. Then, a cold front and its associated trough are forecast to enter the far south coast late Wednesday and cross Sydney Waters on Thursday, with strong southerly winds and large powerful southerly swells in its wake. Strong south to southeasterly winds and hazardous surf conditions may remain during the later part of the week through the weekend as a low pressure system develops off the north coast.
