Average week ahead, windows for Perth
Western Australia Surf Forecast by Craig Brokensha (issued Monday 20th July)
Best Days: Early Wednesday and Friday around Perth, Sunday morning everywhere
Fun Saturday of waves with a new pulse of W/SW swell and light offshore tending variable winds across both regions, while yesterday was poor with a smaller swell and onshore winds.
Today fresh onshore winds continued to create poor conditions with a building swell.
This week (Jul 21 – Jul 24)
A relatively weak but broad frontal system pushing into us today will bring with it a building SW groundswell along with onshore winds.
This swell is due to peak tomorrow in the 8ft range, with 2-3ft sets in Perth and building surf to 4-5ft late in the North West, holding Wednesday morning.
Winds will however continue to be onshore tomorrow from the SW across Perth, and W/SW in the South West, tending more W'ly through the day, which isn't ideal at all.
Wednesday morning will be the time to surf around Perth with early NE winds ahead of a shift to the N/NW through the morning.
The swell will be on the ease though from 2ft+ or so. Margs will remain onshore and poor with strengthen NW winds.
Into Thursday winds will swing S/SW across the South West with a cold front pushing into the south-west corner of the state. Perth looks to also see poor S/SW winds, although there's a chance they may tend S/SE, we'll confirm this Wednesday.
The front will produce a secondary pulse of S/SW groundswell for later Thursday, peaking Friday morning with 6-8ft sets in the South West and 2ft+ waves around Perth. The swell isn't due to hit the North West until Friday afternoon, kicking late to 3-5ft or so.
Winds unfortunately look to remain onshore from the SW across the South West, with early E/SE winds around Perth.
This weekend onwards (Jul 25 onwards)
Another pulse of moderate sized S/SW groundswell is due into Saturday afternoon from the front bringing Friday's onshore winds.
This should come in around the 5-6ft range in the South West and reach 1-2ft late in Perth, before easing back into Sunday and further Monday.
Winds are unfortunately due to remain onshore Saturday from the S/SW, but Sunday should finally see an offshore E/NE'ly across Margs.
Longer term there's nothing too significant on the cards for next week, but more on this Wednesday.
