South Australian Forecast (issued Wednesday 25th March)

Best Days: Friday morning Mid Coast, Saturday down South, Sunday morning down South, Monday and Tuesday mornings both coasts

Recap

Fun waves across the Mid Coast to 1-2ft yesterday with an easing windswell while the South Coast was solid but poor with fresh to strong onshore winds.

Today the Mid Coast was back to a tiny 1ft, while the South Coast was super fun with clean 2-3ft waves at Middleton and 3-4ft sets at Waits and Parsons.

This week (Mar 26 – 27)

A mix of good SW groundswell and junky but solid short-range S/SW swell are due to fill in tomorrow across both coasts owing to an intense mid-latitude low pushing in from the west overnight and stalling to our south through all of tomorrow.

The Mid Coast should kick to a semi-stormy 2ft overnight while the South Coast is due to build to 4-5ft at Middleton and 5-6ft at Waits through the afternoon but with poor and strong S/SW winds.

Come Friday both swells should back away and the Mid will be the best with easing 1-2ft waves under a light morning SE breeze. The South Coast will be solid but average with moderate to fresh but easing S/SW winds.

This weekend onwards (Mar 28 onwards)

The weekend is looking great for the South Coast with Friday's swell due to ease off as some new moderate sized SW groundswell fills in Saturday before easing Sunday.

The source of this swell will be unfavourably aligned frontal activity under the country, producing W/NW fetches. The swell will be mainly aimed south of Tassie but we should see some fun waves spreading up radially into us through the weekend.

Size wise Middleton should still be a good 3ft+ Saturday morning with 4-5ft sets at Waits and Parsons, easing off into the afternoon and further from 2ft to occasionally 3ft and 3-4ft respectively Sunday morning. The Mid is due to be tiny and around 1ft Saturday, becoming near flat Sunday.

A light to moderate and straight N'ly offshore is expected most of Saturday before late and weak afternoon sea breezes. Sunday should then see light NW winds ahead of a SW'ly into the afternoon.

The surf should jump into Monday as a strong new SW groundswell fills in, generated by a strong but fast tracking frontal system from the south-west of WA, towards Vicco over the weekend.

While its track will be a touch too fast the core wind speeds will counter this, with good 3-5ft surf due at Middleton and 6ft sets at Waits, while the Mid should see 1-2ft waves. A secondary weaker front is then forecast to move in quickly on the tail of the initial system, producing a secondary slightly smaller pulse for Tuesday.

Conditions are looking good for both coasts each morning with variable winds tending locally offshore, but we'll review this Friday.
