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

Best Days: Mid Coast keen surfers tomorrow morning

Recap

Effectively flat across the Mid Coast yesterday, with clean but tiny waves off Middleton, best at Waits and Parsons with small fun sets.

Today an onshore change has moved through with a building windswell down South, while the Mid Coast was a poor 1ft, but some new groundswell has filled in with better S/SE winds, with peaky 1-1.5ft sets.

This weekend and next week (Dec 2 - 8)

We're now under the influence of a surface trough, with onshore S'ly winds and small building windswell across the South Coast.

We should also see this afternoon's pulse of W/SW swell on the Mid Coast to 1-1.5ft easing back from a similar size tomorrow, though with average S/SW winds (possibly S'ly at dawn). These winds will also generate some tiny windswell, easing back through Sunday from a tiny 1ft.

Down South though, strong S'ly winds will create moderate amounts of S'ly windswell, but the trough with linger a little further east than forecast on Wednesday resulting in a downgrade in size.

Most breaks should build to a junky 3ft to occasionally 4ft tomorrow afternoon, easing from a similar size Sunday morning as the trough starts to weaken and onshore winds weaken. Conditions will be poor with strong S'ly winds Saturday, more fresh and gusty Sunday.

Monday will be smaller with fading 2ft to maybe 3ft sets but fresh S/SE winds will continue to create poor conditions.

Our small pulse of SW groundswell for Monday and Tuesday is still on track, but it won't have any major size, and winds will persist out of the SE-S/SE.

The swell is being generated by a relatively weak low that's currently south of WA is generating a good pre-frontal fetch of NW gales, followed by weaker post-frontal W/SW winds.

Middleton should build to 2ft+ Monday afternoon, easing from 2ft on Tuesday, while the Mid Coast isn't expected to see any size at all, with tiny 0.5ft sets max.

For the rest of the week onshore winds will persist from the S'th with average amounts of swell. We may see some better swell later in the week/next weekend but winds will remain an issue. Have a great weekend!
