Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 17th December)

Best Days: Thursday morning exposed breaks, Friday morning in the South West, Sunday late morning, every morning from Monday at exposed breaks


Good waves across most locations yesterday morning with a good swell and morning SE breezes before afternoon sea breezes kicked in.

Today the swell was smaller and average with S/SE winds across all locations, leaving semi-protected breaks with the best waves.

This week (Dec 18- 19)

The surf will remain on the smaller size tomorrow but cease from easing as a reinforcing SW groundswell fills in. This is only due to offer inconsistent 3-4ft+ sets in the South West, 1ft+ waves in Perth and 2-3ft sets up at Gero.

Winds will improve and swing offshore from the E/SE during the morning creating great conditions before sea breezes kick in.

Friday should see similar favourable winds, but the swell will be smaller and easing.

This weekend onwards (Dec 20 onwards)

Our moderate pulses of SW groundswell from Saturday through early next week are still on track. An initial increase Saturday is due to be followed by a secondary increase Monday and then third pulse Wednesday and then final pulse later Thursday/Friday.

This will be generated from persistent but not overly strong polar frontal activity in the Heard Island region and further east. Each pulse doesn't look too offer too much size, with peaks in size to the the 3-5ft range in the South West at exposed breaks, 1-1.5ft in Perth and 3ft up at Gero (but there'll be larger levels of local S'ly swell from persistent and strong S'ly winds up the WA coast).

Winds are looking better than they were on Monday with a deepening inland heat trough due to see winds becoming fresh to strong from the SE through Sunday and then E/SE Monday through Wednesday and possibly into Thursday. We'll review this again on Friday though.
