The Lowdown
Alright, let’s get real about the next couple of weeks. It’s a tough stretch for surf, plain and simple. I’m looking at a long, dry spell stretching out for the majority of the next 16 days, with only a couple of weak pulses that barely get the heart rate up. The first real surf on offer is a tiny bump on Thursday the 13th, and it’s a slow go from there. The water is currently sitting at 53°F, which is a whopping 6°F colder than normal for this time of year. That’s not just a little chilly; that’s a full-on, teeth-chattering, hood-and-gloves kind of cold. It’s a notable thing to keep in mind.
The first pulse comes Thursday afternoon at Slip Point (Clallam Bay). It’s a small, short-period west swell, maybe 2ft, with a period of 7 seconds. The energy is weak, just 48, and the onshore wind won't do it any favors. It’s not going to be good, but it’s the only game in town. The next day, Friday the 14th, is even less, with a 1ft WNW bump in the morning and weak energy of 11. That’s it, that’s the whole show for the first week. Basically, we’re looking at a week of flat, onshore conditions. Not a single decent wave to be found.
After that, the surf just goes silent for days. We’re looking at a long gap from Friday afternoon all the way until Wednesday the 26th of August. That’s a serious stretch of nothing, especially for a spot that can be fairly exposed. The wind is mostly onshore, and the swell charts are just empty.
Finally, on the morning of Wednesday the 26th, we get a last-gasp pulse. Another tiny, short-period west groundswell, but it’s small. 2ft at 5 seconds is just not going to break with any power. The energy is a weak 21, and the wind is onshore. It’s a tease, really. It’s not going to be worth paddling out for unless you’re desperate to get wet.
Honestly, for a point break that’s known to handle a good west-northwest swell, this is a frustrating forecast. There is no standout session in this entire 16-day window. All of this looks more like a kite-surfing forecast than a surfing one, with the onshore wind and minimal swell. The only saving grace is that the spot is fairly consistent, so this kind of blank run isn’t the norm. The near-term calls are reliable, but the one on the 26th is a long-shot, so keep your expectations low. The forecasts can change, but as it stands right now, it’s a time to work on your pop-up on land.
