The Lowdown
G'day, Rusty here. Look, I'll be straight with you—this is one of those forecasts where you might wanna take up fishing for a while. The whole 16-day window for Slip Point (Clallam Bay) is a tough watch. There's not a single recommendation worth paddling out for, and the data backs that up. We're looking at a long, blank run right from the start, with no surf worth mentioning for the entire stretch from Thursday, the 13th of August, all the way through to Friday, the 28th of August. That's a solid two-week gap of nothing doing.
Most of the time, the swell energy is sitting at zero, or barely flickering. There are a few moments with some tiny, weak pulses—like on the 13th of August afternoon, you get a 2ft W swell with a short period of 7 seconds, but the combined energy is only (47)—that's weak stuff. A similar little bump pops up on the 19th of August afternoon, again 2ft from the W at 7 seconds, energy at (48). Then around the 25th and 26th of August, there's a slight lift with some 2ft to 2ft W swells, periods creeping up to 10 seconds, and energy nudging into the 50s and 80s. But it's all written off as poor surf conditions every time.
The biggest issue here is the wind. This break loves a SE offshore, but we're getting hammered by onshore wind from the NW and WNW most days, which kills any chance of clean surf. Even when the wind goes light or glassy, there's just no swell to work with. For an advanced point break that's fairly exposed to the WNW, the swell direction is actually matching the optimum now and then, but the size is tiny and the quality is shot.
If you're a beginner, don't even think about it—even the tiny waves that show up are under 5ft, so that's not the problem, it's the total lack of any decent shape. For the experienced crew, this is a kite surfer's window, not a paddle surfer's. The wind is strong and sideshore too often, and the wave state is just too messy. Honestly, these blank runs happen here, and it's a normal part of the game for this area. Things can't stay this flat forever, and forecasts can flip, but for now, I'd save the wax.
Rusty.
