Western Australia Surf Forecast by Craig Brokensha (issued Friday March 19th)

Best Days: Exposed breaks in the South West tomorrow morning, Sunday ahead of sea breezes, protected spots Monday morning

Features of the Forecast (tl;dr)

• Easing SW swell tomorow with morning E/SE tending E/NE winds
• Stronger W/SW swell filling in Sun with light SE winds (E/NE Perth and Mandurah) ahead of sea breezes, deteriorating Mon with a trough and strengthening from the S/SE
• Nothing significant to follow until the following week

Recap

Our good pulse of new W/SW swell filled in right on cue yesterday with clean 4-6ft surf across the South West, though only 1-1.5ft in Mandurah and 1ft across Perth.

Today the swell has eased a touch across the South West but conditions are great again across the South West, small and to 1-2ft in Mandurah and Perth.

This weekend and next week (Mar 20 - 26)

We'll see the swell from yesterday and today easing into tomorrow and the South West magnets will be the pick with a light, offshore E/SE wind, tending E/NE ahead of sea breezes. Expect inconsistent, but 3-4ft sets easing on the South West magnets.

Our good new W/SW groundswell for Sunday is on track, with the mid-latitude frontal progression linked to it currently weakening west-southwest of us.

This progression wasn't overly strong but it was working on the active sea state generated by the fronts before it and this should help generate a good increase in size Sunday, building to 6ft to occasionally 8ft across the South West magnets (possibly a touch undersized early), with 2ft sets developing in Perth and Mandurah from late morning or so.

Winds look favourable and light out of the SE Sunday morning across the South West, E/NE to the north, with afternoon sea breezes. Come Monday a trough will bring strong S/SE winds, limiting options as the swell eases.

These winds will shift slightly SE on Tuesday morning (and remain strong) but the swell will be on the way out, cleaner Wednesday but small and fading from 2ft+ or so across Margs.

Therefore make the most of Sunday's waves.

Longer term there's nothing major on the cards for the end of the week or next weekend, but it looks like we'll see a break in the subdued activity from next weekend and beyond as a strong polar frontal progression fires up under the influence of the Long Wave Trough. More on this in Monday's update though. Have a great weekend!
