The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next 16 days at Slip Point (Clallam Bay) are looking pretty grim. We’re staring down a long stretch of flat, choppy, or just plain poor conditions. It’s going to be a tough run for paddle surfers, so don’t hold your breath.
The first real glimmer of anything surfable doesn’t show up until Wednesday morning, September 2nd. That’s a full week of waiting from now. Before that, from Monday the 24th right through to Tuesday the 1st of September, it’s a desert. We’re talking zero swell energy and poor surf conditions day after day. The water is currently sitting at 54°, which is a staggering 5° colder than normal for this time of year – that’s a serious chill, so if you’re dumb enough to get in, you’ll want a thick suit.
Then, on the morning of Wednesday, September 2nd, we finally get a pulse. A small 2ft west swell rolls in with a period of 10 seconds, pumping a weak 108 (moderate energy) into the bay. The wind is light and offshore from the ESE, which will tidy things up. But don’t get too excited – the forecast says “surfable waves but very ordinary conditions.” It’s tiny, it’s weak, and it’s probably the best we’re going to get in the whole outlook. For a brief moment, it might be okay for a longboard if you’re desperate.
After that little blip, the rest of the period from the 3rd to the 8th of September falls back into the same old pattern. The swell fades to zero, or we get tiny 0.7ft to 2ft dribbles from the west-northwest. The wind is mostly cross-onshore or onshore, making a mess of things. Any small swell that does show up will be choppy and uninviting.
Honestly, for a spot that’s only “fairly exposed” to the swell, this is a classic blank run for the area. The only thing worth mentioning is that brief window on the morning of September 2nd. If you’re a kite surfer, the persistent onshore wind might get your attention, but for a paddle surfer, this is a hard pass. Keep the wax in the car and wait for the next real storm.
Rusty.
