The Lowdown
Alright folks, Rusty here. Let’s have a look at what Slip Point (Clallam Bay) has in store for us over the next couple of weeks. I’ll be straight with you – this isn’t a period that’s gonna have you cancelling your plans, but there’s a couple of windows where it might be worth a look if you’re desperate.
The overall pattern is weak. We’ve got a run of small, short-period westerly swells coming through, but the wind and conditions are all over the place, and there are long gaps with absolutely nothing rideable. For the first week or so, the wave energy is pretty ordinary, and the water temperature is sitting at 53°F, which is a good 5°F colder than normal for this time of year – that’s seriously cool, so a thick wetsuit is non-negotiable.
The best chance to get wet is the very first recommendation, on Friday afternoon, the 11th of September. A small 0.7m (that’s about 2ft) swell out of the west, with a period of 9 seconds, and the wind is glassy out of the ENE at just 3 mph. The combined swell energy is weak at 103, so it’s not gonna have any power, but that glassy wind means the surface will be like a mirror. It’s a point break, and with that direction being close to the optimum WNW, the waves should have a bit of shape. It’s small, so it’s not gonna be a standout, but it’s the cleanest it’ll get all period.
After that, we hit a real dry spell. From Saturday the 12th right through to the morning of Thursday the 17th of September, the surf is rubbish – either onshore winds, no swell, or just tiny, weak waves. There’s a 9-day stretch in there where nothing is worth paddling out for.
Thursday the 17th of September morning offers another tiny glimmer. A 0.7m (2ft) swell from the WNW, period of 8 seconds, with a clean light breeze out of the ESE at 9 mph. The combined energy is still only 72, so it’s weak, but the wind is clean and cross-offshore. It’s surfable, but you won’t be bragging about it.
After that, it’s pretty much game over again until the tail end of the forecast. Friday the 25th and Saturday the 26th of September show a tiny 0.6m (2ft) west swell trying to build, with glassy or clean winds, but by that point we’re 2 weeks out, so don’t get your hopes up too high.
Honestly, this is a lean run for Slip Point. If you are absolutely jonesing, the Friday afternoon glass-off on the 11th is your best bet – small, clean, and you might have it to yourself. But don’t expect much.
Stay salty,
Rusty
