Easing swell through the weekend, becoming onshore through next week
Western Australia Surf Forecast by Craig Brokensha (issued Friday 5th June)
Best Days: Tomorrow morning, Tuesday, selected spots early Wednesday
Wednesday’s building W/SW groundswell held into yesterday morning with clean and great 4-6ft waves across the South West, 2-3ft in Mandurah and 2ft across Perth.
Today a new groundswell has filled in and we’ve got pumping 6ft surf in the South West, 2-3ft in Mandurah and 2ft across Perth again with conditions due to remain clean all day.
This weekend and next week (June 6 – 12)
Today’s new W/SW groundswell will start to ease over the weekend and we’ll see winds strengthen from the E/NE, shifting NE-N/NE through the afternoon and then easing late. Size wise the South West should ease back from 5-6ft in the South West, 2ft+ across Mandurah and 2ft on the sets in Perth, tiny into Sunday. The South West should still see 3-4ft sets Sunday morning but winds look dicey and light NW (N/NE early in Mandurah and Perth). There may be variable winds across the South West but with the swell, not worth worrying about.
A low point in energy is expected Monday with morning E/NE winds, with our new inconsistent W/SW groundswells for Tuesday and then Wednesday still on track. A tight polar low ahead of a broader polar frontal progression south-east of South Africa have generated two swells that should be similar in size, though the first longer-period and the second less so.
The long-period swell might be seen later Monday but peak Tuesday to an inconsistent 5-6ft across the South West, 2ft in Mandurah and Perth on the sets. The secondary swell should keep wave heights around a similar size Wednesday.
Conditions look best Tuesday morning with an E/NE offshore, shifting variable into the afternoon while Wednesday will see less favourable fresh NE tending strong N winds as a mid-latitude front moves in from the west.
The mid-latitude low will bring a moderate sized increased in onshore swell for Thursday, while a stronger polar front following it looks to generate a larger and onshore swell for late week/weekend, but we’ll have a closer look at this Monday. Have a great weekend!
