Best Days: Swell magnets dawn tomorrow around Margs, Saturday morning Margs, Tuesday morning both regions, Wednesday morning Margs

Recap

A slight kick in swell yesterday to 3-5ft in the South West and 1-1.5ft to the north but conditions were average with fresh to strong S-S/SE winds.

Today the surf cleaned right up but there wasn't much size left on the coast.

This week and weekend (Dec 15 - 18)

The surf will become even smaller tomorrow, with inconsistent 2-3ft sets left across magnets in the South West, tiny elsewhere.

We're looking at E/NE winds at dawn in the South West, tending onshore by mid-morning and then back to the SE-S/SE Friday but with strength.

With even smaller surf Friday conditions will be poor and not worth chasing.

A small increase in mid-period and average SW swell is due Saturday, from a weak fetch of polar W/SW winds today and tomorrow.

Not major size is expected with 3-4ft sets due but conditions are looking better with an E'ly offshore ahead of sea breezes. Perth will be very tiny.

Sunday is another lay day with a fresh S/SW change and easing surf.

Next week onwards (Dec 17 onwards)

The mid-latitude low talked about last update us still on the cards, with it expected to form south-east of Madagascar this afternoon and produce a fetch of W/SW gales while tracking east over the coming days weakening south-west of us Saturday evening.

A good W/SW groundswell is due off this low, building Monday to 5-6ft later in the day Monday (1-2ft Perth), easing from 4-6ft Tuesday morning. The swell will be least consistent Monday and more consistent Tuesday due to the later part of the swell being generated closer towards us.

Monday will see S/SE winds as a high pressure ridge moves in from the west, while Tuesday morning is the pick with E/SE offshores ahead of sea breezes.

Longer term there's some similar sized swell due later week but with what looks to be onshore winds. More on this Friday.
