The Lowdown

Alright folks, Rusty here with the long-range look at Slip Point (Clallam Bay). Right off the bat, I gotta be straight with you – it’s a bit of a slow start for the first week or so. The water is sitting at a chilly 53°F, which is a wild 6°F colder than normal for this time of year. That’s a serious drop, so if you’re heading out, a thick wetsuit is non-negotiable.

For the first few days, through the 1st and into early September, we’ve barely got a whisper of swell. The energy is just not there. You’ll see some clean mornings on the 2nd with that light offshore from the SE and the occasional glassy afternoon, but there’s nothing to ride.

There’s a bit of a pulse on the 5th with some small 2ft swell from the west, but it’s weak and pretty ordinary. The 6th offers a slight upgrade; we’re looking at a long-period groundswell of just over 1ft from the WNW, with a period of 13 seconds. That longer period will bring some shape, but the height is tiny. The combined energy is still low. It’s clean on Sunday morning or glassy in the afternoon, but it’s barely surfable.

Then we hit a bit of a gap from the 7th through the 9th. There’s some swell around, but the wind is mostly onshore or cross-onshore, and the energy readings are all poor. The 9th afternoon does show a jump in energy with a 13-second period, but it’s still only around 2ft and the conditions are described as "very ordinary."

Now, here’s the only real standout in the whole 16-day run. The morning of Thursday, September 10th. The wind will be glassy from the ENE, and we’ll finally get some proper swell. A 4-5ft W groundswell with a 13-second period will pour in, pushing the combined energy up to a solid 556. That’s moderate to strong energy, and with glassy conditions, the point should be peeling off nicely. It’s not huge, so it should be manageable for advanced surfers, but the quality is the best we’ll see.

The afternoon of the 10th looks a bit too big at 5ft and the wind swings onshore, so morning is definitely the call. Friday the 11th still has some decent leftover energy from a 4ft W swell with clean cross-offshore winds in the morning. It’s a good follow-up session.

After that, the swell fades fast. The 12th through the 16th are mostly flat or have tiny, weak windswell that isn’t worth the paddle. The energy drops to near zero and the conditions, while often clean, just have nothing to work with.

So, to wrap it up: mark your calendar for the morning of Thursday, September 10th. That’s the only time this outlook really fires. The rest of the window is mostly a waiting game.

Rusty.
