View the current warnings for New South Wales

Forecast issued at 4:05 pm EST on Wednesday 22 May 2019.

Weather Situation

South to southeasterly winds are affecting the central and southern Waters this evening under the influence of a weak low pressure system off the South Coast. Light and variable winds are affecting the northern Waters with a ridge extending from a high pressure system over the Tasman Sea. The low will dissipate on Friday as the ridge becomes predominant over all of the Waters, bringing light winds. A north to northwesterly flow will then develop over central and southern parts on Friday and Saturday as another low pressure system approaches from the Southern Ocean. A front associated with this low will bring a southwesterly change to central and southern parts on Sunday. In the meantime, light winds will prevail in the north under the influence of the ridge.
