South Australian Forecast (issued Wednesday 1st December)

Best Days: Both coasts tomorrow morning, South Coast Friday morning, South Coast Saturday and Sunday mornings, Mid Coast Tuesday afternoon and Wednesday

Recap

Poor conditions across the Mid Coast yesterday with a tiny weak 1-1.5ft of windswell, building to a better and more surfable 2ft into the afternoon. The South Coast was clean in protected locations early but small to tiny, while an onshore change moved through late morning.

Today a peak in W/SW veering SW swell are being seen across the both coasts to a fun 2-3ft across the Mid Coast with S/SE winds and 3-4ft down South with a lingering S'ly wind, which is now only moderate from the S/SW.

This week and weekend (Dec 3 - 6)

South Coast: Our current SW swell should start to ease back through tomorrow but a weak trailing front behind the main system responsible for today's swell will soften the blow.

We should see good easing 3ft+ waves across Middleton tomorrow morning with 4-5ft sets at Waits and Parsons, further down from 2-3ft and 4ft+ respectively Friday morning.

Conditions should improve with winds swinging NE tomorrow morning ahead of afternoon sea breezes, with even straighter conditions Friday under a N/NE'ly.

Saturday morning will start slow and small as we fall in between swells, but a new inconsistent SW groundswell is due to fill in for the afternoon. Inconsistent 2ft sets at Middleton should increase to 2ft to possibly 3ft into the afternoon, with 3ft waves at Waits, pulsing to 3-4ft.

Morning offshore N/NE winds will give into afternoon sea breezes, so the mid-late morning surf is probably best.

The swell should fade from 2ft at Middleton and 3ft at Waits Sunday morning under N'ly offshores again and obligatory afternoon sea breezes.

Mid Coast: Today's good W/SW swell will ease pretty quickly, dropping back to 1-2ft tomorrow and then fading further Friday from 1ft+. Conditions will be great with morning offshores and weak if not variable afternoon sea breezes. Come the weekend only tiny 0.5ft surf is due, possibly pulsing to 1ft Saturday afternoon.

Next week onwards (Dec 7 onwards)

South Coast: Unfortunately there's nothing significant due through early next week as a blocking setup develops through the weekend, leaving us to rely on background swell activity which will be small and very inconsistent.

Clean conditions are due Monday morning but the swell will be tiny, similar Tuesday morning ahead of a late kick in new W/SW swell peaking Wednesday. This will be from a broad and deepening surface low south of the Bight over the weekend before developing a weak fetch of W'ly winds on its northern flank Sunday afternoon and evening. This swell will perform best on the Mid, with the South Coast only likely to see 2-3ft sets from Day St to Goolwa and 3-4ft waves at Waits and Parsons.

Mid Coast: The W'ly swell due off the low forming Sunday should push in Tuesday across the Mid, building to a good 2ft into the afternoon and easing from a similar size Wednesday morning. Winds look best Wednesday but we'll review this again in Friday's update.
