7 day weather forecast

Effective as of 4:00 AM Friday May 7 2021

Explanatory notes:

Showers have contracted to lie offshore as low level winds have become east-southeasterly with land breeze development with low level wind convergence of the land breeze and southerly winds offshore triggering those showers.

Areas of mist and patches of fog early today with light winds and radiational cooling of moist air with moist soils from yesterday's rain.

Ridge of high pressure builds to the south leading to fine conditions from today

Warmer afternoons early next week with warm air advection as the high moves into the Great Australian Bight.

As usual, some uncertainty on the precise conditions towards the end of the forecast period with variation between models and model ensembles.
