The Lowdown
G’day, Rusty here. Look, I’m gonna level with you—this isn’t a classic stretch for Slip Point (Clallam Bay). Over the next 16 days, it’s mostly a story of waiting and hoping, with just a couple of narrow windows that might get your heart beating. There are a lot of quiet days with barely a ripple, and the water is running much colder than normal for this time of year. We’re sitting on 53° currently—a full 4° below where we should be—so a thick wetsuit is non-negotiable.
Kicking off on Thursday the 17th, we finally see a pulse of swell during the morning. It’s WNW at 3ft, period around 9 seconds, with a moderate energy reading of 103. Winds are light and cross-off from the ESE, so conditions will be tidy. It’s surfable but nothing to write home about. That afternoon it drops back to 2ft and goes onshore NNW, so get your session in early.
Friday the 18th morning could be the pick of this first week. The swell holds at 3ft from the WNW, still around 8 seconds, but the wind goes glassy—ENE at 5 km/h. That’s clean, glassy surf, mate. Energy is moderate at 90. It’s small and ordinary, but if you’re desperate, it’s your best chance.
Then things go quiet and small again through the weekend and into Monday the 21st. On Monday morning, a long-period WNW groundswell rolls in at 3ft but with a 14-second period—strong energy at 243. The problem is the wind is cross-onshore from the W at 15 km/h, making it choppy. Monday afternoon bumps up to 5ft from the west with a 12-second period and a very strong energy reading of 613, but that W wind kicks up to 20 km/h cross-onshore, creating a messy, choppy lineup. It’s more of a kite surfing setup than a clean paddle session.
Now, here’s the standout: Tuesday the 22nd morning. The swell still has some push at 4ft from the west, 11-second period, and the energy is strong at 345. The wind is dead calm—SSW at 0 km/h, glassy. That’s the cleanest window in the entire forecast. For a point break that’s fairly exposed to WNW swell, this combo gives you a real chance at a few lined-up, well-shaped waves. It’ll be a bit solid for beginners at that height, but for anyone intermediate and above, this is the morning to point the car.
After that, it trails off. Wednesday the 23rd afternoon offers a small, glassy 3ft west swell at 11 seconds (energy 233), but the writing is on the wall. From the 24th onwards, it’s flat, with only a whisper of a 1.0ft WNW swell on the 28th and 29th, glassy at times, but barely enough for a log. You’re chasing ghosts.
If you want a wave, you’ve got a couple of honest chances: Friday the 18th morning for clean small waves, and Tuesday the 22nd morning for the best size and glass. Don’t hold your breath after that.
Rusty.
