Average weekend, large onshore waves for early next week
Western Australia Surf Forecast by Craig Brokensha (issued Friday 22nd April)
Best Days: Early Saturday protected breaks in the South West, Tuesday protected breaks in the South West, Wednesday Perth and protected spots in the South West
Good clean conditions yesterday morning with 4-5ft of swell across the South West and 1-1.5ft waves further north.
Today the larger long-period swell has provided 5-6ft sets across Margs, with 1-2ft waves further north under a gusty offshore.
This weekend and next week (Apr 23 - 29)
This morning's long-period SW groundswell should ease back through this afternoon, further down from the 4-5ft range tomorrow morning. You'll have to get out there quick though as a fresh and gusty dawn NE'ly will swing N/NE through the day and then more N'ly into the afternoon.
Sunday will then be poor as we fall in between swells with a fresh N/NW tending NW wind.
Into early next week our large pulses of swell are still on the cards but so are the onshore winds.
A very intense mid-latitude low is forecast to develop to our west-southwest tomorrow, producing an initial fetch of severe-gale to storm-force W/SW winds before weakening and moving towards us into Sunday afternoon and evening.
A large W/SW groundswell will result, peaking through the middle of the day/afternoon Monday to 8-10ft+ across the South West and building to 3ft in Perth through the afternoon.
A secondary weaker but broader front pushing up on the tail of the low should generate a secondary pulse of SW groundswell for Tuesday, keeping the surf around the 8ft range most of the day ahead of an easing trend Wednesday from 6ft to occasionally 8ft.
Perth should see 2-3ft sets most of Tuesday, easing from 2ft Wednesday.
Now conditions will be poor across the South West with a strengthening W/NW wind Monday, tending S/SW into Tuesday and easing. Wednesday may see an early S/SE breeze but we'll confirm this Monday.
Perth will also be onshore Monday and Tuesday with E/SE offshores Wednesday morning.
Longer term there's nothing too major on the cards, but check back here Monday for the latest update. Have a great weekend!
