Windy, easing surf

Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 23rd September)

Best Days: Today, tomorrow, Friday morning


Poor surf to start yesterday across the South West though winds backed off through the day and conditions improved, tiny to the north and not ideal.

Today we've got an inconsistent building W/SW groundswell with great conditions across all locations. We should see the South West reach 6-8ft this afternoon (looks to be hitting about that now below), 2ft to maybe 3ft in Mandurah and 2ft across Perth. Winds are due to swing to the south and sea breezey across all locations.

This week and weekend (Sep 24 - 27)

This afternoon's inconsistent W/SW groundswell is due to ease tomorrow as winds strengthen and create tricky conditions. Look for some protection otherwise it'll be blown out and bumpy from the wind.

Strong E'ly winds will ease into the afternoon and the swell should ease from an inconsistent 6ft+ across Margs. 2ft+ in Mandurah and 2ft in Perth, small Friday with strong E/NE morning winds, easing and shifting N/NW across Margs, NW in Perth and Mandurah. So aim for the morning surf.

The small pulse of W'ly swell for Friday is still on track, generated on Monday but a small mid-latitude low and this should keep Perth and Mandurah around 2ft on the sets, 3-5ft across the South West.

The weekend still looks poor with Friday's swell dropping on Saturday with onshore W/NW winds across all locations, lighter but lingering into Sunday.

Moving into week the surf will start to lift in size, but the quality and strength will be low.

A broad and persistent flurry of Southern Ocean storms will annoyingly just sit north enough to bring onshore winds to the South West through all of next week but with no major strength to the fronts, there'll be no major size.

It looks like Perth and Mandurah may see lighter, more variable winds from Tuesday morning, but we'll have to have a closer look at this on Friday.

Size wise we're only looking at surf to the 6ft range across the South West, 2ft in Perth and Mandurah, but more on this next update.
