Western Australia Surf Forecast by Craig Brokensha (issued Monday 11th May)

Best Days: Exposed breaks Tuesday, Wednesday, Thursday morning, north facing beaches early Monday with a NW windswell


Average small onshore waves Saturday with cleaner small 3ft waves in the South West yesterday morning. Perth remained clean but tiny.

A new SW groundswell came in this morning to a better 3-4ft across the South West with offshore winds and a continuation of 1ft sets in Perth.

This week (May 12 - 15)

A better increase in SW groundswell is due through tomorrow across both regions, arriving late morning and coming in at 4-5ft across the South West from midday and hanging around 1ft in Perth. This swell should then drop back through Wednesday from 3-5ft and 1ft respectively Wednesday, becoming tiny into Thursday.

Winds will be favourable for exposed spots though with an E/NE tending variable breeze tomorrow, fresh NE tending lighter N/NE wind Wednesday and then average and strong N/NE tending N'ly winds.

A new long-range and inconsistent W/SW groundswell is due through Friday ahead of a secondary pulse Saturday afternoon and Sunday morning in the 3-5ft range around Margs with 1-1.5ft sets up at Perth (2-3ft around Gero) but conditions will be poor. A strong but easing N/NE'ly is due to persist through Friday with strengthening N/NE winds Saturday.

This weekend onwards (May 16 onwards)

A deepening mid-latitude low to our west over the weekend will produce strengthening N/NW winds down the coast through Saturday evening and Sunday kicking up a moderate sized N/NW swell for Sunday which will be more W/NW in direction across Gero before the low pushes east Monday and brings with it a S/SW change.

Perth should build to 2ft+ later Saturday and hold around 2-3ft Sunday before possibly kicking further late. The South West will be right on the edge of this N/NW fetch and is likely to build to 3-4ft at north facing breaks later Saturday, with bigger 4-6ft waves Sunday but with strong N/NE tending NW winds.

Come Monday the swell will ease from the NW mixed in with a smaller SW windswell in the wake of the low. Winds will be poor in any case and from the SW.

The surf should continue to ease into the middle of next week as winds improve while into the end of the week we may see some larger SW groundswell developing for our region. We'll have a closer look at this on Wednesday though.
