Recap

Clean but easing surf from 2-3ft yesterday morning in the South West, tiny to the north. Some new swell started to show into the afternoon but this hasn't amounted to much today with a continuation of 2-3ft surf and less favourable S'ly winds. Perth and Mandurah were cleaner but still tiny.

This week and weekend (Dec 30 – Jan 2)

Today's small lift of mid-period SW swell is due to ease over the coming days and winds won't be too favourable for the South West with a fresh S/SE breeze, strengthening through the day from the S-S/SW.

Friday will be poor with no decent swell and strong S/SE winds. There'll likely be some weak S'ly windswell in the mix further north but only tiny in Perth and Mandurah while also bumpy.

The weekend will start slow but some new mid-period S/SW swell is due into late Saturday, though peaking Sunday.

As touched on in Monday's update, a broad but weak frontal progression will project north-east towards us with fetches of strong SW winds produced in our southern swell window.

Size wise we're only looking at surf to 3-5ft across the South West on Sunday when it peaks, tiny to the north and maybe 1-1.5ft in Mandurah with 1ft sets across Perth.

A secondary stronger low firing up on the tail of the weak progression should generate some stronger though still mid-period energy for Tuesday. Size wise this looks to come in at a better 4-6ft though Mandurah and Perth will remain tiny.

Winds will improve into early next week but Sunday looks tricky with gusty S/SE-SE morning winds, stronger S-S/SW into the afternoon. Monday should see a fresh morning SE breeze ahead of those less favourable afternoon winds, while Tuesday looks to see similar fresh SE winds.

Wednesday looks to offer the best conditions as winds shift E and the mid-period S/SW eases.

Longer term the surf will ease into the end of the week along with a return to strong SE-S/SE winds, so try and make the most of next week's mid-period S/SW swells.
