The Lowdown
Alright, here’s the deal. It’s been a flat old stretch here, and to be honest, the next couple of weeks aren’t going to win any awards. We’ve got a long gap of nothing happening before anything even gets close to rideable, so don’t hold your breath just yet.
The water is sitting at 53°, which is a solid 4° colder than normal for this time of year. That’s a big jump, so if you’re heading out, you’re going to need the thick rubber. It’s a real shock to the system when you first get in.
From Monday the 14th right through until Wednesday the 16th, it’s small and weak. We’re looking at waves around 1ft to 2ft, with the swell coming from the west or west-northwest, but the energy is just not there—combined swell energy is only 19 to 58. It’s pretty much flat and unrideable. The wind is light, mostly glassy at times, but there’s nothing for it to push around. It’s a write-off.
Then Thursday the 17th and Friday the 18th, things stay small. You might see a bump up around 3ft, but it’s still very ordinary. The combined energy finally gets over 100, which is something, but it’s weak-moderate at best. You could get a wave if you’re desperate, but it’s not going to be pretty. The swell direction is more west-northwest now, with clean conditions and light offshore winds in the morning. Still, it’s barely surfable. I’d give it a miss unless you’re just needing to get wet.
The weekend is flat again. Saturday the 19th and Sunday the 20th, we’ve got nothing but small, weak swell and onshore winds. It’s messy and small, not worth the paddle.
Now, here’s the one little highlight in this whole stretch. Monday the 21st into Tuesday the 22nd, we finally see a pulse of groundswell. The period jumps up to 13-14 seconds, so there’s some real energy behind it. The swell height is around 3ft on Monday afternoon, pushing 4ft on Tuesday morning. Combined energy sits at 339 and 345—that’s the most we’ve seen all week. The direction is west, and with light offshore winds early Tuesday, it’s going to be clean. That Tuesday morning window is your best bet of the whole outlook. It might not be huge, but it’s the only time the ocean actually wakes up.
But here’s the catch—that long period, 13-14 seconds, can make it tricky at Slip Point (Clallam Bay). It’s a point break, so it should handle it, but those long intervals can make the waves a bit walled-up at times. Still, it’s your best shot.
After that, it dies off again. From the 23rd through the 27th, there’s no swell at all. The forecast shows nothing—zero energy. The wind is okay, mostly cross-offshore or glassy at times, but there’s simply no waves. It’s a long dry spell.
Finally, at the very end, on Monday the 28th and Tuesday the 29th, there’s a tease. The swell shows up again, but it’s tiny—1ft to 2ft. The period is long, around 13-14 seconds, so it’s got some push, but the height is just not enough. Combined energy is 64 to 89, which is weak. It’s surfable for a longboard on the right tide, but it’s not going to get your heart racing. So if you’re keen, you might get a slow, clean one on Tuesday morning, but don’t expect much.
Overall, this is a pretty barren forecast. The one standout is definitely the Tuesday the 22nd morning session—it’s the only time where everything lines up decently. Everything else is either flat or just too weak to bother with. Keep your board in the car, but don’t get your hopes up.
Stay patient.
