The Lowdown
Alright, let’s talk about Slip Point. Honestly, partner, this is a tough one to get excited about. Over this whole 16-day stretch, the surf just ain’t showing up in a way that gets the heart pumping. We’re looking at a long, blank run with nothing worth paddling out for.
Right now, on Tuesday the 18th, there’s a tiny bit of swell barely registering, a weak 2ft from the west with a short 7-second period, and the combined energy is just 52 – that’s weak. On top of that, the wind is onshore and the conditions are poor. The water is sitting at a chilly 52°, which is much colder than normal for this time of year, so you’re gonna feel that bite. After that, from Wednesday the 19th all the way through the end of the month, it’s mostly flat. A few mornings might be glassy, but with zero swell, it doesn't matter.
There are little hiccups of energy, like a 2ft swell on Saturday the 22nd and again on the 31st, but the period is short, the wind is generally onshore or cross-onshore, and the overall energy remains weak (below 100). The first few days of September don’t offer much hope either, with barely a ripple.
There’s really no standout period here. The best you might get is a glassy morning on Monday the 31st with a tiny 2ft west swell and 7-second period – clean conditions, sure, but it’s small and weak. For the pick of the bunch, you’d have to look at that morning: Slip Point (Clallam Bay) will be clean with glassy conditions, but don't expect any power. The optimum swell direction is WNW, and this is coming from straight west, so it’s not ideal. For a more reliable wave, you’d need a bigger, better-aligned groundswell, which just isn’t in the cards.
For a spot that’s fairly exposed, these are lean pickings. The swell just isn't there. Hang in there, things might change.
