This weekend and next week (Dec 29 – Jan 3)

The weekend is looking really fun with a strong front that's currently passing under us generating a good mid-period SW swell for tomorrow morning along with offshore winds.

The South West should see good 5-6ft waves tomorrow morning, with 2ft surf in Mandurah, 1-2ft in Perth, easing slowly through the day. Conditions look excellent across the South West and an E/SE offshore, possibly even tending E/NE for a period ahead of afternoon sea breezes, with morning SE winds to the north.

A secondary strengthening front south-west of us this evening, quickly moving off to the east will produce a reinforcing SW swell for Sunday to 4-5ft, if not for the rare bigger bomb, 2ft in Mandurah again and 1-1.5ft in Perth.

Winds should be good and SE early, but a shift to the SW is expected sooner rather than later, so don't sleep in too long.

Winds Monday will be average at dawn but improve through the morning with a S/SE'ly tending E/SE through the day ahead of sea breezes with smaller easing surf from the 4ft range across the South West, 1-1.5ft in Mandurah and tiny in Perth.

Our longer-period SW swell for Tuesday is still on track, with a stronger low forming in the Heard Island region expected to produce a tight fetch of gale to severe-gale W/SW winds, weakening while projecting north-east towards us.

Mid-period energy will build ahead of the groundswell on Tuesday, with a peak likely overnight, easing Wednesday.

Margs should build to 6ft+ by dark Tuesday but with sea breezes, 2ft+ in Mandurah and and 1-2ft in Perth, easing back from 5-6ft, 2ft and 1-2ft respectively Wednesday.

Unfortunately an approaching trough looks to create average conditions Wednesday, bringing onshore W/SW winds.

This trough may form into a deep low pressure system off our coast, though the models diverge on this at the moment, so check back Friday for an update on later next week. Have a great weekend!
