South Australian Forecast (issued Monday 23rd December)
Best Days: Wednesday, early Thursday, Saturday morning
Friday afternoon's increase in stormy S/SE windswell eased back to 3-4ft on Saturday across the South Coast and conditions improved during the day as the trough linked to the swell drifted south-west. This resulted in fresh morning E/SE winds backing off and swinging light offshore into the afternoon. The Mid Coast was tiny and clean with the stiff offshore.
Yesterday saw much smaller waves across the coast with a mix of background SW groundswell and fading S/SE swell under morning W/NW winds.
The trough moved back in during the afternoon, bringing onshore winds with it, with a sloppy and messy 2-3ft wave seen across the South Coast today and tiny to flat conditions on the Mid Coast.
This week (Dec 24 - 27)
Cleaner conditions are expected tomorrow morning but there won't be much swell left after today's windswell drops overnight. Light variable winds should swing NE, favouring exposed locations.
Christmas Day is looking fun as a new S/SW groundswell fills in and peaks during the afternoon. This is linked to a strong polar low that's currently to our south-west (pictured right), with most spots expected to reach 3ft Wednesday afternoon, with 4ft sets at Waits and Parsons. The Mid will miss the swell due to its southerly direction and come in at 0.5ft.
Winds on Wednesday will be great and from the N/NE ahead of a swing to the NW and then late shallow change, so try and surf before early afternoon.
The swell will ease Thursday but winds look dicey, lingering from the S/SW and increasing during the day.
A new SW swell is due into Thursday afternoon and Friday morning generated by a mid-latitude front pushing in under the country over the coming days. Winds will remain average though and be fresh to strong from the S/SE. This will create clean waves on the Mid though, with 1ft waves expected from this swell.
This weekend (Dec 28 – 29)
The weekend looks average with onshore winds form the SE and small to moderate amounts of S/SW swell. Saturday morning will be the best time to surf with a morning E'ly and 2ft of S/SW swell.
Longer term there's nothing major on the cards so make the most of Wednesday's swell.
