Recap

Great waves across the South Coast magnets yesterday with clean conditions and 2ft sets off Middleton, more 3ft across the magnets, while today the swell has dropped back a little. The Mid Coast has offered tiny wind affected waves for beginners.

This week and nexy (Jul 6 - 14)

We've got a strong pulse of W'ly groundswell due tomorrow across the state, generated by a severe low that has been battering Western Australia since the start of the week. A slow moving fetch of gale to severe-gale W/SW-W winds has generated the swell with it due to peak across the Mid Coast in the strong 3ft range while Middleton looks to offer 3-4ft sets (bigger down towards Goolwa).

The remnants of the low are expected to push north and across us through tomorrow, bringing strong N tending NW winds. This will favour the South Coast and create choppy conditions on the Mid.

Come Friday, the groundswell is expected to ease but the next frontal system in a strong progression will move in quickly. This will bring strong NW tending near gale-force N/NW winds into the afternoon/evening, kicking up a building windswell across the Mid Coast followed by some new mid-period W/SW swell. Stormy 3-4ft waves are likely into the afternoon while the South Coast is due to ease back from 2-3ft.

Now, unfortunately the progression as a whole looks weaker and more northerly located, not ideal for the South Coast. This will result in large stormy waves on the Mid Coast but weaker mid-period energy down South.

Saturday looks to come in at a stormy 3-4ft on the Mid Coast with strong W'ly winds, dropping back to 3ft on Sunday with fresher W/SW-W winds.

The South Coast looks the pick with building mid-period energy Saturday afternoon to 4-5ft off Middleton, easing back from a similar size Sunday morning.

Winds should tend more W/NW across the South Coast Saturday and Sunday mornings, favouring protected spots, with W/SW winds likely into the afternoon Sunday.

Following the weekend's frontal activity, we've got a ton more mid-latitude frontal systems lining up with the swell not likely to drop below the 2ft range on the Mid Coast and 3-4ft down South through most of next week.

The next swell generating system will be a tight low generating a good spike in swell for Tuesday but we'll have a closer look at this Friday. Winds look to be generally out of the NW for most of next week as well which is great.
