Western Australia Surf Forecast by Craig Brokensha (issued Friday 20th March)

Best Days: Sunday in protected spots, Monday everywhere, every morning for the rest of the week at swell magnets


A strong pulse of SW groundswell pushed in yesterday with workable winds across all coasts from the south, but today was the day to surf, with the swell easing from a pumping 6-8ft in the South West, 2-3ft in Perth and 5-6ft up at Gero under straight offshore winds.

Winds have remained favourable into the early afternoon and may do so for the rest of the day.

This weekend and next week (Mar 21 - 27)

I hope you made the most of day, as tomorrow is looking average across all locations with Sly tending S/SW breezes through the morning and an easing swell.

A strong pulse of S/SW groundswell Sunday is still on track, generated by a vigorous polar low tracking from Heard Island, east along the polar shelf the last couple of days.

The South West should see this swell peaking through the middle of the day to 6-8ft at exposed breaks, 2ft+ in Perth from midday and 3-5ft up at Gero into the afternoon.

Winds will improve but only slightly with a strong SE'ly due across all locations through the morning, tending more S/SE into the afternoon.

Monday will be the day to surf as winds swing offshore from the E/SE across all locations with a drop in size from 5-6ft in the South West, 2ft on the sets in Perth and 3-4ft up at Gero.

Tuesday will be smaller again, with the swell bottoming out Wednesday morning under straight fresh to strong E'ly winds.

A small pulse of inconsistent SW groundswell is due through Thursday but to no major size, generated along the polar shelf by weak and unconsolidated frontal activity.

Size wise we're probably looking at 3-4ft waves at best in the South West Thursday with 1ft sets in Perth and 2-3ft waves up at Gero. Winds should continue to play nice though and be offshore from the E/NE.

Longer term there's no significant frontal activity progged for our near to medium-range swell windows leaving us to rely on longer-range, small and inconsistent groundswell energy into next weekend and beyond. We'll look into this closer on Monday. Have a great weekend!
