Great weekend, large again early next week
Western Australia Surf Forecast by Craig Brokensha (issued Friday 23rd August)
Best Days: Saturday, Sunday, Monday, Tuesday
A window of good conditions across all locations yesterday morning with Wednesday's large swell dropping back to 8-10ft yesterday morning, 2-3ft in Perth and Mandurah.
Today the wind and swell are on the build again with poor conditions across all locations.
This weekend and next week (Aug 24 - 30)
Today's swell should reach the 10-12ft range in the South West this afternoon, 3-4ft in Mandurah and 3ft in Perth and winds will swing more S'ly later in the day across Margs, favouring protected spots.
Due to the longevity of the strong conveyer belt of frontal systems through our swell window the last week, the easing trend will be slow, with similar sized surf due tomorrow morning as winds improve.
A moderate E'ly is due down in the South West, E/SE further north ahead of weak sea breezes.
Sunday looks good again with E/SE offshore winds and a further drop in swell, half the size of Saturday morning and dropping from 6ft+ in the South West, 2ft+ in Mandurah and 2ft across Perth.
Moving into next week and there's been no real change to the large, long-period but very inconsistent W/SW groundswell due into Monday afternoon and Tuesday morning.
A fetch of storm-force W/SW winds were generated mid-this week south of South Africa, in our far far swell window, with the storm weakening slowly while moving east yesterday and today.
The swell should build Monday and kick to a large 10ft+ across the South West by late afternoon, 3ft in Mandurah and 2-3ft in Perth.
Winds look good again and E/NE through the morning, ahead of sea breezes and fresher from the E/NE tending N/NE Tuesday as the swell eases.
Longer term we're looking at a large and windy swell developing later next week and into the weekend a strong mid-latitude frontal progression moves, through persisting most of next week under a strong negative Southern Annular Mode signal. More on this Monday. Have a great weekend!
