Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 30th July)

Best Days: Thursday from Mandurah north, Friday, Saturday morning, Sunday, Monday, Tuesday


Largish onshore conditions continued into this morning across all coasts besides Gero which has seen a morning offshore and a large pumping swell.

This week (Jul 31 – Aug 1)

There's been no real change to the forecast tomorrow with a large and powerful SW groundswell expected to build to 10ft+ through the afternoon with 12ft bombs while Perth should build to 3ft+ late and Gero to 6ft+, peaking early Friday to 6ft to occasionally 8ft.

Winds will improve across all locations but be best from Mandurah north with SE tending S/SE breezes (Gero should see an early E/SE'ly). Margs will be cleanest in protected spots with a S/SE breeze.

Friday however looks excellent with the easing swell and E/NE tending N/NE winds (holding NE into the afternoon north of Margs).

This weekend onwards (Jul 2 onwards)

Saturday will be the low point in activity and variable winds should create generally clean conditions but into Sunday a large and powerful W/SW groundswell is due to fill in, generated a series of strong cold fronts. An initial fetch of severe-gale SW winds south-east of South Africa yesterday set up an active sea state for a much broader and stronger frontal system to generate an additional fetch of severe-gale W/SW winds over from today through until Friday morning.

Racing in behind this will then be a third front with stronger storm-force winds at its core, generating a secondary larger SW groundswell for Monday morning.

The initial W/SW groundswell should build strongly late in the day Sunday, pulsing to 10ft+ in the South West, 3ft+ in Perth and 6ft to possibly 8ft in the South West. Monday morning should see the SW groundswell peak to 10-12ft in the South West, 3-4ft in Perth and 6-8ft+ up at Gero.

Now winds look great with offshore tending variable breezes on Sunday and then E/NE tending variable winds on Monday opening up plenty of options depending on your ability and an epic day of surfing across the state.

After Monday's large groundswell we'll see wave heights slowly tail away away through the week with a reinforcing SW groundswell only slowing the downwards trend. Winds look to remain generally favourable but we'll review this Friday.
