The Lowdown
Listen up, gang. Rusty here. I’m looking at the 16-day picture for Slip Point (Clallam Bay), and it’s a real bummer. We’re staring down a long stretch of flat, lifeless conditions. The first glimmer of a wave doesn't show up until Monday, August 10th, and it’s a bare-minimum kind of day.
On the morning of August 10th, a tiny swell shows up. We’re talking about 4ft waves out of the west, with a short period of 8 seconds. The combined energy is moderate at 200, so it’s got a pulse, but it’s weak. The wind is glassy, dead calm, which is a massive plus. That means the surface will be clean, even if the rain is falling. The water is running at 52°F, which is a staggering 6°F colder than usual for this time of year. That’s a serious anomaly, so you’ll need a thick wetsuit, hood, and boots.
That single morning is the only real highlight. The morning of Tuesday, August 12th, has a clean, cross-offshore breeze, but there’s zero swell to ride. The rest of the forecast is a wasteland of cross-onshore winds and tiny, unrideable slop.
This spot is a point break, and it’s fairly exposed to the WNW, which is the right direction. The problem is there’s no energy in the water. For a spot that’s known to be inconsistent, this kind of blank run is more normal for the area. It’s a waiting game. The one window on the 10th is the only thing on offer, and it’s a weak one. Don’t get your hopes up.
Rusty.
