The Lowdown
Alright, Rusty here again, looking at the same setup but in feet and knots.
This is a quiet stretch for the Strait. Most of the next 16 days are small and weak, with one brief window that might make it worth the effort.
The best of the lot is shaping up for Friday, September 11th. The morning session at Slip Point (Clallam Bay) shows a clean 4ft swell from the west with a 9-second period. The wind is light offshore out of the ESE, keeping the surface clean. The combined swell energy hits 263 (moderate energy), which is the highest we’ll see. The water is running at 55°, which is a bit cooler than average for the season, so suit up.
Saturday, September 12th still has a little push with a 3ft swell from the WNW and light offshore wind, but the energy drops to 141. It’s surfable, but nothing special.
After that, it’s a long fade. From Sunday the 13th onward, the swell stays under 3ft, and the energy drops into the double digits. There are a few glassy mornings, like on the 16th and 19th, but the waves just aren’t there. The last few days, from the 17th to the 20th, are mostly flat with zero energy.
So, if you want to paddle out, focus on the morning of Friday, September 11th. That’s the one real chance. The rest is a long stretch of small surf and flat spells. Forecasts can always change, but right now, it’s a patience game.
Rusty.
