Recap

The swell spiked up considerably through yesterday, generated by the strong low south of the Bight on Sunday/Monday. The Eyre Peninsula bore the brunt of of swell with the South Coast kicking to a strong 4ft with clean conditions. The Mid offered waves but with plenty of cross-shore wind making for average conditions.

Today the swell is on the ease with choppy surf inside the gulf, best down South.

Chunky sets yesterday morning

This week and weekend (Jun 27 - Jul 5)

The remnants of the strong low in the Bight is currently moving across us, bringing a weak fetch of W/SW-SW winds and small pulse of energy to 2-3ft across Middleton tomorrow, fading Friday.

Conditions will be clean all of tomorrow with a NW tending N/NW breeze, strengthening N-N/NW on Friday with the next approaching mid-latitude low through the Bight.

The models were a little divergent regarding the movement and strength of this low but we’re now looking at some consolidation with it due to strengthen while moving in and then positioned itself south of us on the weekend.

With this, we’ll see a fetch of gale to severe-gale S/SW winds projected up and into the South Coast, with a large S/SW groundswell mixed in with some mid-period energy due to build Sunday, easing slowly Monday as the low weakens and moves east.

Middleton looks to reach 6ft+ at the peak of the swell with 1-2ft waves in the gulf, but with strong W/SW-SW winds Sunday, S/SW tending S on Monday. This will effectively create poor conditions throughout the peak of the swell with the Mid Coast likely seeing periods of S/SE winds on Monday.

Easing surf is due into the middle of next week as winds tweak a little more S/SE on Tuesday (tiny on the Mid Coast), cleaner down South Wednesday but small.

Longer term some good W/SW groundswell is due later week from a strong frontal progression through the Southern Ocean in our medium to far swell window, but check back Friday for more on this.
