Western Australia Surf Forecast by Craig Brokensha (issued Wednesday 15th April)

Best Days: Thursday morning, Friday morning, keen surfers in the South West Saturday morning, Perth and Mandurah Monday and Tuesday mornings

Recap

A building swell and good conditions early yesterday with 4-5ft sets across the South West, 1-2ft further north, bigger into the afternoon but choppy.

Today we've got fresh to strong onshore winds and poor conditions with a building swell.

This week and weekend (Apr 16 - 19)

The cold front that's currently pushing up and across the corner of the state will continue off east overnight, clearing as the SW groundswell it's creating peaks.

This swell should provide good 6-8ft waves across the South West tomorrow morning, 3ft in Mandurah and 2-3ft across Perth, easing through the day.

Winds should swing around to the E/SE across all locations tomorrow morning, though only light in the South West with a bit of lump and wobble likely from today's onshore mess.

Friday should be straighter and cleaner with a moderate to fresh E/SE offshore and there'll still be plenty of size as a reinforcing S/SW groundswell from the base of the progression moving through today softens the easing trend.

The South West should still be 6ft on the swell magnets, 2ft+ across Mandurah and 2ft in Perth. As touched on in Monday's notes, Saturday will see less favourable morning S/SE winds as the swell continues to drop in size.

Further on Monday's outlook regarding the run of onshore winds from Sunday through early-mid next week, it's still on track, but the frontal progression linked to this looks a bit weaker and the swell along with the onshore winds smaller.

We'll see a broad but weak polar front projecting from the Heard Island region tomorrow, with it pushing slowly north-east before up and into us Sunday and Monday.

A large mid-period SW swell is expected on Monday, likely to 6-8ft in the South West again but with strong W'ly winds, cleaner to the north and 2ft to occasionally 3ft on the sets.

Onshore winds will persist Tuesday and Wednesday as the swell eases, cleaner again in Perth and Mandurah but easing from a small 2ft on the sets.

Longer term there's nothing too significant showing, but more on this Friday.
