Large and windy weekend, easing into next week

South Australian Forecast by Craig Brokensha (issued Friday 1st May)

Best Days: Experienced surfers Sunday down South, beginners on the Mid, Monday down South


Poor and onshore conditions across both coasts yesterday with a mix of groundswell and building windswell, larger and stormier today as we fall under the full effects of the deep, cold and intense low that's formed to our south.

This weekend and next week (May 2 - 8)

The run of strong onshore winds and stormy surf will continue into the weekend as the low that's currently south of us remains very slow moving while strengthening this afternoon and evening.

What we'll see is our current fetch of strong to gale-force S/SW-SW winds that are being aimed into us weakening a touch tomorrow, but a fetch of severe-gale to storm-force S/SE-S winds south-west of Tassie, projecting north this afternoon and evening will produce a large and powerful S'ly groundswell for very late tomorrow and more likely Sunday morning.

In the interim we'll still see large surf down South, likely to 5-6ft but with strong SW winds. The Mid Coast will remain choppy and stormy and to 2-3ft.

Sunday morning will likely see 6-8ft sets across the swell magnets down South, easing steadily through the day though and then smaller from 3-4ft Monday morning, 2ft into the afternoon off Middleton. The Mid Coast looks to ease back from 1ft to maybe 2ft on Sunday, tiny Monday.

Winds on Sunday will ease but remain onshore down South, moderate from the S/SW but abating through the day creating decent workable conditions for experienced surfers. The Mid should see a morning S/SE breeze.

Monday still looks fun down South with an offshore N/NE breeze and the quickly easing S'ly swell.

Longer term there's nothing too major on the cards for next week until later when a series of funky mid-latitude lows move in from the west, possibly bringing some new W/SW swell, but more on this Monday. Have a great weekend!
