The Lowdown
Alright, folks, Rusty here. Let’s be straight with you. Looking at the next couple of weeks, we’ve got a pretty bleak stretch ahead for Trestles (Lowers). It’s one of those times where the ocean’s just not cooperating, and we’re going to have a long gap with no real surf on offer.
The whole window starts off with a whimper. From now through the middle of next week, the swell is just tiny, barely pushing 1ft to 3ft. The periods are all over the place, mostly short and weak, and the energy is minimal. The first few days, the energy is reading around 150-200, which is just weak. The wind is mostly light, but it’s often blowing from the SW, which is straight onshore, and that’s going to chop up whatever crumbly little waves there are. It’s a real bummer, just a lot of closeouts and knee-high slop.
The water temp is a big story though. It’s sitting at 76°, which is a full 9° warmer than normal for this time of year. That's just crazy warm, so if you’re just going to get wet, it’s a pool. But for surfing, it’s not worth getting the board wet.
The swell tries to pick up a bit around the 7th and 8th, with a longer period groundswell from the SSW showing up. The energy jumps up into the 400s, and the period gets up to 19 seconds, which is a proper long-period swell. But the size is still nothing. We’re looking at 2ft to 3ft faces. For a break like this, that’s just not enough to get over the sandbar. The light onshore winds are still going to be messing with it, so it’ll be bumpy and weak.
We then have a long stretch through the middle of the month where the surf stays poor. The energy fluctuates, but the height stays below 3ft. The wind remains light but mostly onshore or cross-onshore. It’s just a frustrating pattern of tiny waves and less-than-ideal conditions. The wave comment just says “poor surf conditions” day after day, and that’s exactly what it’s going to be.
The one glimmer of hope comes on the 15th of August. We see a pulse of SSW swell that pushes the height up to 4ft. The energy is up to 738, which is the strongest of the whole run. The period is a solid 16 seconds, so it has some push to it. The wind is light and onshore, but it’s still the best looking day of the whole period. It’s still not big, but it might be the only day you can actually catch a few proper waves. The morning looks best with some clouds and light wind. After that, it backs off again, and we’re back to the small, poor stuff through the end of the run.
So, to be honest with you, there’s nothing here that’s a true standout. The day on the 15th is the one to keep an eye on, but even that is just a “maybe” for a quick session. The forecast for the tail end of the second week is too far out to trust completely, but it’s not looking promising. This is a stretch where you’re better off doing something else, because the surf just isn’t going to be there.
