The Lowdown
Right, let’s see what we’ve got around here. Honestly, it’s been a tough stretch. For the next few days, it’s looking pretty bleak with next to no rideable surf. We’ve got a bit of a dry spell from now until around August 30th, with only small, weak energy showing up and even that is getting chopped up by cross-onshore breezes. Not worth paddling out for.
Things start to look a tiny bit better on the morning of Sunday, August 30th. We get a little 2ft swell from the west at Slip Point (Clallam Bay), and the wind goes glassy. The combined swell energy is still weak, only 47, but it’s clean. Unfortunately, the wave comment calls it “poor surf conditions,” so it’s really only a chance to get wet without getting thrashed. The water is sitting at 56°F, which is a bit colder than normal for this time of year – about 3°F off – so factor in a good wetsuit.
The best looking window across the whole forecast lands on the morning of Monday, August 31st. We’ve got a 2ft west swell, period up to 10 seconds, and a light cross-offshore breeze from the east at 3 mph. That will keep things clean. The combined energy is still low at 67, and it’s only rated as “surfable waves but very ordinary conditions,” but it’s the best we’ll see for a while.
We then hit another long gap of very little to nothing until the morning of Friday, September 5th. That morning brings back a similar 2ft west swell with clean, cross-offshore wind, but again, it’s marginal.
The one spot that stands out as the best in this outlook is the morning of Sunday, September 6th. We get a 1ft groundswell from the west-northwest with a very long period of 13 seconds. That long period means more shape and energy behind each wave, and with the combined swell energy reading 111, we’re into moderate energy territory for the first time. The wind is light and cross-offshore from the east at 6 mph, so it will be clean. At point breaks like this one, that long period will really shine. It’s small, but it’s the quality pick for anyone who knows how to make the most of a good line.
The morning of Monday, September 7th, shows a bump to 3ft from the west-northwest with an 11-second period and a combined energy of 150 (moderate). But the wind is onshore, which will mess it up.
Overall, there are very few standouts. If you’re desperate, the morning of August 31st is your best early bet, but the real pick is the morning of September 6th – just be ready for small, clean, long-period lines. Crowds are possible at Slip Point, so if you see a few others out, don’t be surprised.
