South Australian Forecast by Craig Brokensha (issued Friday 22nd September)

Best Days: Saturday morning South Coast, Mid Coast Monday keen surfers

Recap

OK waves yesterday morning down South before a change pushed through, while the Mid Coast was tiny but saw some new swell later in the day.

This W/SW swell has peaked today with inconsistent but clean 2ft sets across the Mid Coast while the Middleton stretch was around 2-3ft with a straight offshore. Waits and Parsons are the pick though with bigger better sets.

This weekend and next week (Sep 23 - 29)

Today's fun W/SW groundswell should tend more SW in direction and ease back slowly through tomorrow. The Middleton stretch should continue to offer 2-3ft sets early morning, smaller into the afternoon along with light N/NW tending gusty W/NW winds.

The Mid Coast is likely to be back to 1-1.5ft tomorrow morning but the afternoon will see increasing levels of W/NW windswell likely to 2ft by dark.

This strengthening W/NW breeze will be linked to an intense mid-latitude low moving east through the Bight and with this we'll see a stormy increase in W/SW swell through Sunday.

The Mid should come in at a stormy 3ft Sunday morning with strong onshore W'ly winds, easing through the day. There's likely to be 4ft sets on the incoming tide with the peak of the swell but conditions won't be nice.

With the low passing across us Sunday the swell will ease back quickly into Monday from 2-3ft.

The swell isn't ideal for the South Coast with the west in its direction with tiny surf expected Sunday morning, increasing towards 2-3ft off Middleton later Sunday but with a W/SW breeze.

The W/SW swell will be replaced by some better aligned S/SW on Monday afternoon from a fetch of S/SW winds the backside of the low.

This swell is due to build into the afternoon, with small 2ft waves through the morning, reaching 3ft into the afternoon and then easing back form 2-3ft Tuesday morning.

Winds Monday morning should tend W/NW around Victor, then back to the SW through the afternoon. The Mid Coast will be bumpy but workable with the easing onshore winds.

Tuesday will become cleaner on the Mid Coast with S/SE tending SE winds but the swell looks to be fading from 1ft. The South Coast looks average.

Through the middle of the week there's nothing significant on the cards, but later in the week we should see some solid S/SW swell filling in, persisting through the weekend and early next week.

A strong node of the LWT is forecast to develop over the Bight late next week, pushing slowly east into the weekend, bringing with it series of strong and broad polar storms.

We'll see lots of sizey groundswell energy generated for the state but it's too early to nail down the particulars of this setup yet so check back Monday for an update on how late next week/weekend is shaping up. Have a great weekend!
