The Lowdown
Alright folks, Rusty here. Let’s have a look at what the next couple of weeks are shaping up like for Slip Point (Clallam Bay).
Right off the bat, I gotta be straight with you – this is a tough run. We’re looking at a long, dry spell with nothing worth paddling out for. From Friday the 21st of August all the way through the end of the month, it’s pretty much a flat, blown-out mess. There’s a few days with a tiny bit of energy, like a 2ft west swell on the 22nd and 25th, but the wind is either onshore or cross-onshore, and the period is short. The water temperature is sitting at 53°, which is a whopping 6° colder than normal for this time of year – that’s seriously unusual and will bite through any wetsuit you’ve got.
We get a small window of hope on Tuesday the 1st of September. It’s still tiny – a 2ft west swell, but the wind goes cross-offshore out of the ESE, and conditions are clean. The combined energy is still weak at 69, but it’s surfable. Nothing to write home about, just a chance to get wet.
The best of the whole outlook, and I mean the only real standout, falls on Thursday the 3rd of September. By the afternoon, we’ve got a WNW swell at 2ft with a 10-second period, and the wind swings offshore from the ESE at 12 mph. That offshore breeze will clean it right up. The combined energy ticks up to a moderate 136. This is the one session in the next two weeks that has any real quality. For a point break like Slip Point (Clallam Bay), a longer period groundswell like that can wrap in nicely. Expect a few longer lulls between sets, but the shape should be there.
After that, it fades again. Friday the 4th of September morning sees a bigger 4ft west swell with a moderate 281 energy, but it’s coming with mod rain and cross-off wind – looks more like a choppy session than a clean one, and the tide might be fighting you.
So, to sum it up: unfortunately, there’s a big gap of no surf from now until the start of September. Then, if you’re keen, target the afternoon of Thursday the 3rd. That’s your best bet by a long shot. The rest is a waiting game.
Stay keen, Rusty.
