Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 28th of May)

Best Days: Friday, Saturday morning, Sunday morning around Perth and Gero

Recap

Small onshore waves continued yesterday across the South West through to Perth, while Gero saw nice clean conditions with 3ft of swell during the morning.

Today a new swell has been building across the state with solid 6ft+ sets now showing in the South West but with fresh onshore winds. Further north conditions were cleaner with 1-2ft of swell around Mandurah and up to 2ft around Perth with lighter morning offshore winds. Gero was also clean and since this morning wave heights have built further but with less than ideal winds.

This week (May 28 - 30)

Today's increase in W/SW groundswell is due to peak this evening across most coasts and then drop off into tomorrow. Winds will remain poor in the South West and from the S/SW ahead of a late swing to the S/SE, while Perth also looks average now with a moderate to fresh S'ly breeze. Gero will be OK but not great with morning SE winds.

As pointed out on Monday though, Friday will be the day to surf as a new W/SW groundswell arrives from our medium-range swell window (around and west of Heard Island). This swell will be inconsistent but should peak in the 6ft to occasionally 8ft range in the South West, 2ft to nearly 3ft in Perth and 4-5ft+ up at Gero as winds swing offshore from the E/NE. A variable breeze into the afternoon is more than likely across most coasts, creating a full fun day of surfing.

This weekend onwards (May 31st onwards)

Saturday morning will be the best time to surf if you're around Margaret River over the weekend as winds will increase from the N/NE from mid-morning onwards and go NW Sunday. Similar winds are due around Perth and Gero Saturday, and the'll hold from the N/NE into Sunday, favouring more exposed regions of coast.

Swell wise, Friday's W/SW swell will drop into Saturday but a new W/SW groundswell is due to arrive through Sunday afternoon, generated by mid-latitude frontal activity currently occurring north-east of Heard Island.

Into early next week, a change related to a weak front moving in from the west will bring onshores to all regions Monday, swinging from the W/NW to W/SW and no considerable increase in swell.

Beyond this we'll continue to see mid-latitude fronts firing up in the Central Indian Ocean north of Heard Island through next week, generating medium sized pulses of W/SW groundswell but local winds look to continue from the NE to NW. We'll review this again Friday so check back then for an update.
