Mix of mid-period and long-period W/SW swells for Wednesday with W/NW winds, fading Thursday. Onshore change moving through Friday, poor through Saturday, improving Sunday.
Today’s westerly change has no redeeming features of than its influence on surface conditions.
Large new S/SW groundswell for tomorrow morning with offshore winds, onshore and smaller Wednesday. Improving conditions slightly Thursday but best Friday with a new weak mid-period S/SW swell.
Building and strengthening W/SW swell energy tomorrow, with a large powerful SW groundswell peaking Wednesday with good winds. Easing Thursday under freshening offshores for the South Coast. Average from Friday.
Building and strengthening mid-period W/SW swell tomorrow with westerly winds, large W/SW groundswell peaking Wednesday with favourable winds for the Surf Coast. Easing Thursday under northerly offshores, average weekend.
The synoptic chart says it all: a cut-off mid latitude low just SW of the state is driving strong westerly winds into the lower SW of Western Australia.
Saturday morning should offer the best waves of the weekend. But, keep your expectations low as there’s not going to be a lot of quality.
Not much more than an easing trend expected this weekend.
At this stage we should see solid 6-8ft surf across exposed parts of the South Coast on Wednesday, whilst he Mid Coast is looking at tidally influenced 2-3ft surf throughout the day (smaller on the outgoing phase).
I’m really impressed with the way the models are tracking this system through the Southern Ocean - it reaches maturity in an ideal part of the swell window (south of WA) but also has most of its initial stages at a reasonably low latitude (50S or lower) which means it’ll spend a lot of time within our swell window.
