The Lowdown
Alright, Rusty here, checking in on Slip Point (Clallam Bay). Let me tell you, the prospects for decent waves over the next two weeks are a pretty tough pill to swallow. We're looking at a real flat spell, so don't be getting your hopes up for anything worth paddling out for.
The water temperature is hanging in there at 53°F, a solid 4°F colder than normal for this time of year, so that's a bit nippy for the first few days.
Honestly, the best bet we have in this whole forecast is a window from Thursday the 17th through to Friday morning the 18th. It ain't saying much, but it's the only time we see any moderate wave energy (103 for combined energy). On Thursday afternoon the 17th, the swell picks up a tiny bit to 3ft from the WNW with a 9-second period, and the wind turns glassy from the NW at 3 mph. That's about the cleanest you'll see this spot get, but the waves are just small and ordinary. Friday morning the 18th, it’s still glassy from the NE at 3 mph with that same weak 3ft swell from the WNW, so you might get a fun little peak if you’re a longboarder or on a foamie.
But man, beyond that, it’s a quick death. By Friday afternoon, conditions go onshore and the swell drops off a cliff. Then we hit a huge dead zone from the 21st of September all the way through the morning of the 26th of September. That’s over five days of nothing, just zilch for swell. Even when we do get a little bump of 2ft on the 26th, the wave comment still calls it poor. Right at the tail end, on the 29th, there’s a weak 1ft WNW swell but it’s cross-onshore and messy. It’s just not happening.
Honestly, with the swell being so tiny and the winds often cross-off or glassy on those few poor days, the setup doesn't even look interesting for kite surfing. It’s just a flat, disappointing stretch for anyone. Forecasts can change, but right now, leave the board at home.
Rusty.
