The Lowdown

Alright, Rusty here. Looking at the next couple of weeks in the Strait, it’s a pretty quiet stretch. The first real chance to get wet doesn’t come until the morning of Sunday, September 6th, and even then, it’s more about the conditions than the size.

For the first week, from August 30th right through to Saturday, September 5th, there’s practically nothing. Tiny, weak swells with poor winds and zero surf quality. The water is running much colder than normal for this time of year, so you’ll want the thickest wetsuit you own.

The standout—and I’m being generous—shows up on Sunday, September 6th, at Slip Point (Clallam Bay). This is a point break, fairly open to the swell. We’re talking a tiny 1ft swell from the WNW, but the key is the period. That 13-second groundswell is long, so it’ll have some real shape and energy for a point. The combined energy is still weak (81 in the morning), but the wind is perfect. Sunday morning has a light east breeze, making it cross-offshore and clean. Sunday afternoon turns glassy. That’s your window. The waves will be small, clean, and well-shaped for a longboard. The spot can get crowded sometimes, so keep an eye out.

Monday, September 7th, the swell drops to 2ft with a shorter 11-second period, and the wind turns onshore, so that window is gone. Tuesday, September 8th, has a glassy morning with 2ft swell, but it’s only a 1 out of 10. The afternoon sees a bump in energy (102) but the wind goes onshore, ruining it.

After that, from Wednesday, September 9th, onward, the forecast goes flat. No swell, no energy, just clean winds and nothing to ride. It’s a dead run for the rest of the second week.

So, if you’re looking to paddle, your best bet is the glassy windows on Sunday, September 6th. It’s small, but it’s the only clean, rideable surf on offer.

Rusty.
