The Lowdown
Alright folks, Rusty here.
We’re looking at a lean 16 days for Slip Point (Clallam Bay). It starts off quiet, with the first real surf not showing up until Saturday the 6th, but it’s only a tiny 1.3ft with a nice 13-second period. The water is 55.0°, which is a bit colder than usual for this time of year, so suit up.
The one true standout is Friday the 11th. That morning, the swell jumps to 5ft from the W with an 8-second period, and combined wave energy hits 309 (moderate). The wind is offshore from the ESE, keeping it clean. This is the best on offer—a punchy wave for the advanced crew, as it’s pushing the limits for beginners. The combined energy is moderate (309), so there’s some power behind it.
Before that, Wednesday the 9th afternoon is a solid session: 3ft from the WNW, 12-second period, and glassy NNE wind. Energy is 236 (moderate), and it’s clean. Not a standout, but a good wave.
After the 11th, it fades quickly. The rest of the 16 days is mostly tiny, under 1.5ft, with very low energy readings (often in the 20s and 30s), and the wind is often onshore or cross-on. The 19th and 20th have zero swell at all—a total flat spell. Saturday the 12th morning has 3.3ft from the W with offshore E winds, but it’s ordinary and weak energy (162).
Bottom line: Friday the 11th is your only real standout. The rest is a long, flat, or blown-out run.
