South Australian Forecast by Craig Brokensha (issued Friday 3rd March)

Best Days: Later Monday through Tuesday Mid Coast, Tuesday morning onwards South Coast


Poor waves down South with onshore winds and a building swell yesterday, while the Mid Coast saw tiny 1ft waves with a small sneaky swell.

Today the South Coast remained poor and onshore, while the Mid Coast saw clean conditions but tiny 0.5ft leftovers.

This weekend and next week (Mar 4 – 10)

Later today we're expected to see a good pulse of S/SW groundswell. This swell has hit the Cape Sorell buoy off Tassie and jumped strongly and we should see it arrive late afternoon across our coasts.

This swell will persist into tomorrow morning with 3ft sets off Middleton, bigger at Waits and Parsons before easing through the afternoon, smaller Sunday. There'll also be some poor S/SE windswell in the mix.

Unfortunately the period of better E'ly winds possible for tomorrow morning down South isn't on the cards anymore, with weakening SE breezes, freshening into the afternoon again.

Sunday will then see poor conditions all day with a strengthening S/SE breeze.

As talked about last updated, poor conditions will continue into Monday with fresh SE tending S/SE winds, while a lighter more variable E/NE'ly should develop Tuesday morning.

A new inconsistent SW groundswell should build Monday and then hold Tuesday across the state, generated by a strong frontal system in our far swell window south-west of WA the last couple of days, dipping towards the polar shelf today and tomorrow.

This swell should build to an inconsistent 2-3ft across Middleton later in the day Monday, with 1-1.5ft sets on the Mid Coast, holding a similar size Tuesday and then easing Wednesday.

Wednesday will become even cleaner down South with a light N/NE offshore before sea breezes kick in.

Come Thursday the surf will be small and mainly around 2ft, but conditions are looking good for most of the day.

Longer term theres still nothing major on the cards, but more on this Monday. Have a great weekend!

Craig, hypothetical question for you. If weather systems moved east to west instead of west to east, would SA get
1) less swell,
2) more swell
3) about the same
4) stupid question.

Less swell due to SA being in the shadow of Tasmania.

Cool question!

yeah i thought LESS to , are you assuming lows & highs would spin in the opposite direction, or it doesnt matter due to Tassie?

Yeah I'd be expecting them to spin opposite. But still yeah it and the South East would block swells a little with 'east' in them. Haha.
