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

Best Days: Perth Tuesday morning, Thursday morning and Friday morning, possibly both coasts Sunday morning

Recap

Lots of swell across the South West over the weekend and into this morning but with relentless onshore winds. Perth and Mandurah were better with better 2ft sets under offshore winds. Today though onshores were in with another building W/SW swell.

This week and weekend (Aug 16 - 21)

A large increase in W/SW swell through today across the state will ease back through tomorrow, dropping from 8ft on the sets in the South West and 2ft+ in Perth.

Our window of cleaner conditions in the South West looks to have been cut a little short, with a dawn N/NE'ly likely to swing N/NW mid-morning, creating poor conditions. Perth will be cleaner for longer with an E/NE offshore swinging NW into the afternoon.

Our larger increase in stormy W/SW swell through Wednesday has been downgraded a touch with the mid-latitude front pushing into us being a little weaker than forecast last Friday.

In saying this conditions are due to be poor in any case with a gusty NW tending SW breeze across all regions (possibly N/NE at dawn around Perth). Size wise Perth should kick to a messy 3ft later in the day, easing from a similar size Thursday morning. Margs should kick to 6-8ft later in the day, also easing from the same size Thursday.

Onshore SW winds will continue to plague the South West Thursday, with Perth possibly seeing an early S/SE'ly, but conditions will remain raw.

Friday will be much cleaner around Perth with E/NE offshores but easing 1-2ft sets, while W/NW winds push into Margs.

From the weekend into next week, there's plenty more swell to come, but also plenty more wind for the South West.

A moderate to large W/SW swell is due to build Saturday, easing slowly Sunday but with onshore winds across all coasts Saturday, while Sunday may see a light variable wind at dawn if we're lucky across the South West. We'll have another look at this Wednesday.

Into next week some larger groundswell is on the cards but the onshore winds don't look to let up, more on this Wednesday.
