The Lowdown
Alright folks, Rusty here. Let me tell you, it's been a rough patch out here at the Strait. We're looking at a real quiet stretch ahead, so don't get your hopes up too high.
We're starting off with a proper blank. From right now through Sunday, the 31st of August, there's really nothing doing. Flat, glassy conditions, but no energy to speak of. It’s a tough start.
Then, finally, on Monday the 31st of August, we see a whisper of life. Slip Point (Clallam Bay) picks up a tiny 2ft W swell with a period of 8 seconds. Monday morning has clean conditions with a light E cross-offshore wind, so it’ll look nice, but with weak wave energy (31), it's really just a knee-high dribble. Not something to rush out for. That little bump fades again into nothing by Thursday, September 3rd.
Honestly, nothing in this whole 16-day window stands out as a true standout. It's a long, drawn-out lull. The water temperature is sitting at 55°, which is about 4° colder than what’s normal for this time of year – a bit of a shock to the system if you’re not used to it.
The one spot that gets close to being worth a mention is later on, Wednesday the 9th of September. We get a small groundswell from the W, 2ft to 2ft, but with a very long period of 13 seconds and moderate energy (137 to 166). That long period means the wave shape will be there, but for a point break like Slip, that's actually a good thing. The morning has clean cross-offshore wind, and the afternoon goes glassy. It’s not big, but if you’re desperate for a long, slow glide on a clean face, that Wednesday morning and afternoon might be your best prayer. It’s still just a small wave, but it’s the cleanest we’ve got.
Beyond that, it's more of the same: tiny bumps and onshore mess. The whole run just feels stuck in neutral. Keep your board waxed and hope the forecasts change, because this is about as bleak as it gets for real surf.
Stay patient,
Rusty.
