Recap

Yesterday started slow with a low point in energy, but a new inconsistent W/SW swell built through the afternoon, coming in at 4-5ft. This morning the swell has held in nicely with clean 4-5ft sets continuing across the South West, 1-2ft in Perth and Mandurah but inconsistent.

Fun sets today

This weekend and next week (May 20 - 26)

The current inconsistent W/SW swell will be replaced by an even less consistent, long-range SW groundswell later today but more so tomorrow morning.

This swell, generated south of South Africa is due to peak this evening, easing back from a slow 5-6ft tomorrow morning on the South West magnets, 1-2ft in Mandurah and 1-1.5ft across Perth.

Fresh E-E/NE tending variable winds are due tomorrow, gusty E/NE tending NE on Sunday with tiny easing waves in Perth and Mandurah, dropping from an inconsistent 4ft in the South West.

A small, reinforcing mid-period S/SW swell should maintain 4ft sets across the South West Monday morning, before easing through the day, smaller Tuesday. This will be generated by a late forming frontal progression to our south-west, generating pre-frontal W/NW winds and local winds will be best early, E/NE-NE, before shifting N/NE through the day.

Unfortunately there's not much on the cards for Tuesday/Wednesday, with some weak mid-period S/SW swell on the cards for Thursday afternoon, easing through Friday.

This will be generated by a weak frontal system pushing up towards the South West of the state Wednesday, but continuing east, under the country.

The South West may see 4-5ft sets later Thursday, easing from a similar size on Friday, tiny to the north. Local winds should be favourable and offshore each morning Thursday and Friday, with variable winds into the afternoons.

Longer term there's still nothing major due at this stage but we'll have a closer look at this Monday. Have a great weekend!
