The Lowdown
Alright, let's have a look at the next couple of weeks. I'm not gonna lie, it's looking pretty flat out there. For Trestles (Uppers), the first run of days from the 2nd through the 9th is basically a non-starter. We're seeing tiny swells, mostly from the southwest, with wave energy readings that are just pitiful.
The first week is a total washout. The swell is weak and the wind is onshore, making it a messy, blown-out situation. You'd be better off working on your pop-up in the driveway. There's no power behind anything, and we're just seeing small, weak lines that don't have the oomph to do anything.
We get a very subtle increase in energy around the 14th and 15th of August. The swell direction straightens out from the SSW, which is good, and the period gets a bit more consistent. But the size just isn't there to make Trestles (Uppers) really start to work its magic. The wind is more cross-onshore from the west, which will add a bit of texture to the surface.
Honestly, there's just nothing that's going to get the heart rate up. The consistent theme here is small, weak surf with not enough height to overcome the average conditions. The energy readings are moderate at best, and most sessions are just not worth the paddle out. No standouts, no glory days in this forecast. Keep the board in the car, and maybe go for a hike.
