The Lowdown
Alright folks, Rusty here. Let’s talk about what’s heading our way.
Well, I gotta be straight with you – it’s a tough stretch ahead for Slip Point (Clallam Bay). The next week and a half is looking pretty grim. There’s a long, dry gap from now until the end of August with nothing really worth paddling out for. The swell is tiny, the wind is mostly onshore or cross-onshore, and the energy is weak. You’ll see a few pulses of swell around 2ft to 2ft, but with periods under 10 seconds and poor conditions, it’s just not gonna come together. 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 cut through any wetsuit that’s not thick enough.
We finally get a little glimmer of hope on September 6th, Sunday morning. It’s not a classic, but it’s the best we’ve got. We’re looking at a 3ft swell rolling in from the WNW, with a solid period of 11 seconds. That’s a proper groundswell, and the combined energy climbs to 202 (moderate wave energy). The wind is light offshore from the ESE, swinging glassy later, which should clean things up nicely. This is a point break, so a long-period swell like this will wrap in nicely here. The crowd factor is “sometimes,” so you might have a few friends out, but nothing crazy. This is your standout window, but it’s a long way off, so keep your fingers crossed. After that, the swell drops back out.
For the rest of the run, the surf is basically flat or too sloppy to bother with. If you’re a beginner, nothing here is for you. Honestly, on the days with a bit of wind and swell, the setup here looks more interesting for kite surfing than paddle surfing.
Rusty.
