The Lowdown
Alright, this is Rusty coming to you from the Strait. Let's talk about what's going on at Slip Point (Clallam Bay).
Honestly, for the first week and a half, it’s a pretty quiet stretch here. There’s a bit of small wave energy around, but the conditions just aren’t coming together for anything worth paddling out for. Most days are showing readings below 2ft of swell, and the energy readings are low, sitting in the double digits like 70 or 57, which is barely a ripple. The water is sitting at about 54°F, and that's 4°F colder than normal for this time of year, so it’s a lot chillier than you'd expect – definitely a full winter suit kind of vibe if you were to go in.
Saturday the 12th has a tiny 2ft from the west, but wind is messy. You might be able to find a clean little wave early on Tuesday the 17th when the swell is still only about 2ft from the WNW, but the energy is still weak at 80. We don’t really have anything to get excited about until later in the window.
Now, here’s a glimmer of hope. On Tuesday the 22nd of September, things start to change. The morning shows a long-period groundswell rolling in: 2ft from the west with a period of 14 seconds. Energy jumps up to 198 – that's moderate energy. It’s clean with a light cross-off breeze. But the real standout is the Tuesday afternoon session. The swell bumps up to 3ft from the WNW, the period holds at 13 seconds, and the energy jumps to 286. The wind goes glassy with a slight air from the NNE. That’s about as clean as it gets. That afternoon looks like the best on offer in the whole 16-day stretch. That longer period means better shaped waves and more push, but keep in mind at a spot like this, those sets will have longer gaps between them.
Wednesday the 23rd afternoon also has some potential with 3ft from the west, a period of 11 seconds, and a glassy surface, though energy drops a bit to 238. It’s still a decent call.
Just a heads up: the last few days of the window slide back into poor conditions with onshore wind and rain moving in, so your best bet is to mark that Tuesday the 22nd afternoon session.
Stay stoked, and I'll catch you in the water.
