Recap

Good waves across the South West with a mix of easing W swell from Friday and background SW groundswell, biggest Saturday, smaller yesterday and tiny to the north.

Today we’ve got deteriorating conditions and small surf, a lay day.

This week and weekend (Jul 2 - 6)

Today’s strengthening winds are linked to a cold front spawning off a strong frontal progression to our west, with it bringing large pulses of W/SW and SW groundswell over the coming days.

The fetches within the progression were a little under the expected strength but we should still see the South West building to 10ft on the sets later tomorrow, peaking Wednesday morning to 10ft+, 3ft in Mandurah and 2-3ft across Perth.

A secondary pulse of reinforcing SW groundswell from a fetch of gale to severe-gale W/NW winds moving south-west of us today and tomorrow is still on the cards for Wednesday afternoon with sets to 10ft due to persist in the South West, easing back Thursday from 8ft on the sets, 2-3ft in Mandurah and 2ft+ across Perth.

Local winds tomorrow now look dicey at dawn but should improve across northern locations with early, strong S/SW-S winds easing and shifting S/SE, most so later in the day across the South West.

Wednesday onwards looks excellent with moderate to fresh E/NE tending E winds due across the South West, E/SE-E to the north, gusty E/NE Thursday morning, lighter into the afternoon.

Friday will then see stronger E/NE tending NE winds as the swell fades, smaller into Saturday with NE-N/NE winds.

We’ll see winds strengthen further into Sunday and Monday as a deepening, high-riding mid-latitude low moves in from the west. Low quality northerly windswell followed by westerly energy is expected along with onshore winds but we’ll have a closer look at this on Wednesday.
