This week and weekend (May 24 – 27)

Make the most of the current waves and weather as we're in for large cold stormy conditions from later tomorrow and more so Friday.

We'll see smaller leftover W/SW swell across the South West tomorrow morning to 4ft, 1-1.5ft in Perth and Mandurah along with a dawn N/NE-NE breeze, fresh and tending N'th by mid-morning, strong into the afternoon, kicking up a building N/NW windswell.

Moving into Friday and a severe low is forecast to develop off the South West with a ftech of severe-gale to storm-force W/SW winds forming through the day.

This will kick up a large stormy SW swell through the afternoon along with strong to gale-force W/NW tending W/SW winds.

Perth and Mandurah look to come in at 3-4ft, while Margs is likely to build to 10ft+ through the day.

The low will remain strong into Friday evening pushing east through Saturday with XL easing stormy surf from 12-15ft along with strong W/SW winds and easing 3-4ft waves in Perth and Mandurah.

The surf will remain large and messy on Sunday with the arrival of a new long-period SW groundswell from a more distant polar fetch of severe-gale to storm-force winds. Conditions will remain poor though with strong W'ly winds.

More large long-period SW groundswell energy is due Tuesday, generated by patchy though strong fetches through the Southern Ocean, but ahead of this a strong front pushing into us Monday will kick up more large windswell.

As touched on Monday though, a small high is expected to move in from the west Monday evening, bringing offshore E/NE winds on Tuesday morning and the long-period swell energy.

We're probably looking at easing 8-10ft surf in the South West and 2-3ft waves further north, but more on this Friday.
