Western Australia Surf Forecast by Craig Brokensha (issued Monday 15th December)

Best Days: Tuesday morning, Thursday morning exposed coasts, Saturday and Sunday semi-protected spots

Recap

Workable waves across the South West over the weekend, best Sunday morning, while Perth was bumpy each morning and biggest Saturday morning. Today a new SW groundswell has filled in but onshore winds have created poor conditions in Margs, while Perth saw a small window of variable winds and clean 2ft'ers. Geraldton saw 3-4ft waves but poor conditions with a S'ly.

This week (Dec 16- 19)

Today's building SW groundswell should continue to increase to 6-8ft later today in the South West and peak overnight before easing through tomorrow from the 6ft+ range.

Perth should offer 2ft waves while Gero should peak through the early morning to 4-5ft before easing.

Winds should improve from today's onshores with a light SE'ly due across the South West and Perth, with Gero also likely to see winds tend SE through the morning. Make the most of it as the swell will continue to fade through Wednesday as unfavourable S/SE winds kick in again.

The drop in size will be halted into Thursday as a long-range and inconsistent SW groundswell fills in. There isn't expected to be much size attached to it with infrequent 3-4ft+ sets due around Margs through the morning, 1ft+ sets in Perth and 2-3ft waves around Gero.

Winds will swing offshore from the E/SE across Margs and Perth, while Gero should see SE tending E/SE winds for a stage during the morning. Friday will be smaller as fresh SE winds return, so also make the most of Thursday morning.

This weekend onwards (Dec 20 onwards)

From Saturday we should see moderate sized and inconsistent levels of SW groundswell across the state from distant and not particularly strong polar frontal activity in the Heard Island region.

An initial pulse is due Saturday to 4-5ft, 1-1.5ft and 3ft respectively across all regions with a secondary similar sized pulse for Sunday. Winds are expected to persist from the SE with strength, but we'll review this again on Wednesday.
