Western Australia Surf Forecast by Craig Brokensha (issued Monday 29th September)

Best Days: Tuesday morning, Wednesday, possibly Friday and Sunday mornings

Recap

The weekend was poor across all coasts with onshore winds and large pulses of swell. Gero saw more variable winds early yesterday opening up more options across the region, while today fresh N/NE winds again opened up selected locations for business with a large SW groundswell.

This week (Sep 30 – Oct 3)

The coming days are looking great for surf across the state with a fresh pulse of SW groundswell due to fill in tomorrow afternoon keeping the South West topped up with 6-8ft surf, 3ft waves in Perth and 4-5ft sets around Gero.

Winds will improve tomorrow quicker than expected, swinging light offshore from the E/SE across all locations (more SE up around Gero) ahead of S/SW sea breezes.

As the swell eases Wednesday conditions are looking excellent with fresh E/NE winds across the state that should tend variable across most locations besides Gero which will see SW winds into the afternoon.

The good conditions well come to an end into Thursday morning as a new long-range SW groundswell peaks, generated in the Heard Island region over the last day or so. This should keep 5-6ft sets hitting Margs with 2ft waves in Perth and 3-4ft sets up at Gero.

Perth and Gero are likely to already be onshore at dawn from the NW but Margs may see a brief period of NE winds before swinging NW and then giving way to a SW change. This will create poor conditions so make the most of the coming two days of waves!

Once winds go onshore Thursday they're unfortunately expected to linger through Friday and the weekend as a secondary front approaches from the south-west and crosses us Saturday evening. We may see variable winds both Friday and Sunday mornings, but we'll have to review this on Wednesday.

In any case a new large W/SW groundswell is due to fill in Saturday and then ease Sunday with a better swell in the wake of the frontal system for Monday but we'll look at this again on Wednesday.
