The Lowdown
Alright folks, Rusty here. Let’s take a long, hard look at what the next few weeks are serving up at Slip Point (Clallam Bay). Straight up, this is a tough run. The water’s sitting at 53°, which is a jaw-dropping 6° colder than normal for this time of year – that’s very unusual, so you’ll want a thick hood and mitts if you’re even thinking about it.
Right now, we’ve got a dry spell that drags on for a good long while. From Saturday, 22 August, all the way through Friday, 5 September, there’s just nothing worth paddling out for. Day after day shows poor surf with tiny to no swell, and even when the wind is clean, there’s no wave energy to work with. The light glassy conditions on Thursday morning, 27 August, and again on Sunday, 30 August, are a tease – beautiful conditions but a flat ocean. It’s a real bummer, a solid two-week gap with zip.
Then, finally, things start to look promising. The real standout lands on Saturday, 5 September. We’ve got a 5ft swell rolling in from the west with a moderate 10-second period, giving us a solid moderate wave energy of 486. That raw energy pushes up to 653 by the afternoon, with the swell dropping just slightly to 5ft but the period stretching out to a very long 13 seconds – proper groundswell. This is a point break, so that long-period energy will wrap in cleanly and line up nicely. The morning is clean and cross-off, and the afternoon turns glassy with a light easterly breeze. That’s a window of excellence.
Sunday, 6 September, still has some life, but it’s a step down. The morning offers a 3ft west swell at 12 seconds, with clean cross-off winds from the east-southeast, but it’s only rated as marginal. The energy (279) is solid, but it’s not the highlight.
So, if you’ve been waiting, mark your calendar for Saturday, 5 September. That’s the session. It’s a while away, so keep an eye on it, but it’s the only real standout in this whole 16-day window. Get on it.
Stay frosty,
Rusty
