The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks at Slip Point (Clallam Bay).
To be straight with you, this is a slow stretch. The first few days are basically a write-off – nothing worth paddling out for until Friday the 4th. From there, we’ve got a long run of very small, weak swell that’s more about getting the cobwebs out than scoring anything memorable. The water temperature is sitting at 53°, which is a whopping 6° colder than usual for this time of year – that’s a brutal anomaly, so a thick wetsuit is non-negotiable.
The real standout, and I mean the only one that gets the blood pumping, is on Wednesday the 9th. The morning sees a jump in energy with a combined swell energy of (412) and a solid 3ft of swell from the WNW at a long 14 second period. That’s proper groundswell, and for a point break like Slip Point, that long period is a dream – it’ll wrap in nicely and offer some real shape. The issue is the wind is a light cross-onshore, which will put a few ripples on the face. It’s not perfect, but it’s far and away the best we’ll see. The afternoon bumps up to 4ft from the W with 13 seconds and energy hitting (556), but the wind swings more onshore, making it choppier. That morning session is the one to target if you’re keen.
After that, the 10th and 11th offer some clean, glassy conditions with small 3ft to 4ft swell, but the energy is moderate at best (217 and 256). It’s rideable, but nothing to write home about. The 13th of September has a late afternoon pulse of 3ft at 14 seconds from the WNW with energy of (273), but the wind is onshore, so it’s a gamble.
For the rest of the second week, the swell fades back to almost nothing. There’s a lot of flat spells from the 15th onward. This spot is a fairly exposed point, and when it’s on, it’s a gem. But for this 16-day window, it’s mostly a waiting game with one real highlight on the 9th.
Stay patient, and keep an eye on that Wednesday morning.
