The Lowdown
Alright, let's talk about Slip Point (Clallam Bay) in feet and miles. It's a rough patch, and I'm not gonna sugarcoat it. The water is 55°F, which is much colder than normal for this time of year, so you'll be wanting a thick suit.
The wave energy is puny, with combined swell energy often in the weak range, like 76, 52, or 92. There's a big gap at the start with pretty much nothing—from Sunday, August 30th, through the first week, it's mostly flat or just messy windswell. The first real opportunity comes on the morning of Tuesday, September 8th, with a tiny 1ft swell from the WNW, but with a very long period of 15 seconds. The wind is light and cross-offshore from the ENE, keeping the surface clean. The combined energy is still only 75 (weak), so it's a longboard or a paddle, not a proper surf.
The standout is the morning of Wednesday, September 9th. The swell picks up to about 2ft from the WNW, with an 11-second period and a combined energy of 126 (moderate). The wind is glassy from the north, so it'll be clean and smooth. It's a point break, so it handles these longer-period swells well. Still, it's small.
After that, it goes flat again. The overall rating is poor, and with so much onshore wind, this setup looks more interesting for kite surfing than paddle surfing for most of the 16 days. The second week doesn't bring any change—more tiny swell and dirty wind.
If you're really keen, go for that glassy Wednesday morning, September 9th. Otherwise, it's a waiting game.
Rusty.
