The Lowdown
Alright folks, Rusty here. Let’s take a look at what we’ve got coming down the pipe.
First up, we’re looking at Slip Point (Clallam Bay). Straight up, the water’s sitting at 55°F, which is a bit colder than normal for this time of year – a good 4°F off, so you’ll want a thick suit.
The outlook starts slow with a few days of nothing much. Friday the 28th and Saturday the 29th are basically flat and poor. Sunday the 30th is glassy but still flat – a real tease.
We finally see a little pulse on Monday the 31st in the morning. A small 2ft swell from the west, period is 10 seconds, combined energy is weak at (94). The wind is light and cross-off from the east, keeping it clean. It’s surfable, but honestly, it’s pretty ordinary.
Wednesday the 2nd of September is where things get interesting. The morning is tiny at 1ft from the WNW with a very long 15-second period, but it’s glassy. Then Wednesday afternoon picks up proper: 4ft of west swell with a 12-second period, glassy conditions, and the combined energy jumps to (404) – that’s moderate energy and a real standout. That afternoon session is your best bet in the whole window. Clean, punchy, and a proper long-period groundswell. That’s the one to circle.
After that, it tails off again. Thursday the 3rd is flat, and the rest of the first week and into the second week is a mix of small, weak swells and onshore or cross-onshore winds. There’s a little bump Monday the 7th of September with 3ft from the WNW and a 12-second period, energy at (232), but the wind is cross-onshore and choppy. Not worth getting excited about.
The 9th of September morning gives us a clean, glassy 2ft swell from the west with a 12-second period and moderate energy (118), but it’s tiny.
Overall, this is a pretty lean run. The one true standout is Wednesday the 2nd of September afternoon. Get on it if you can. After that, it’s mostly small and messy.
Rusty.
