Trestles (Uppers) Surf Forecast and Surf Report

Alright, let’s break it down. The coming two weeks are a mixed bag, mostly small and messy, but there's a glimmer if you’re willing to wait.

Right now, through this week and into the next, the swell is tiny and the wind is mostly blowing across the waves. That means bumpy, grovelly conditions with not much power. The water temp at Trestles (Uppers) is about average for the season, nothing out of the ordinary.

Wednesday morning the 9th starts with a weak 2ft SW swell, but the period is a long 16 seconds. The wind is cross-onshore from the west at 6 mph, which ruins the surface. Combined swell energy is moderate (422). It’s a rough start. Thursday the 10th brings a slight bump to 3ft from the SW with a 17-second period, but again, cross-on south winds at 6 mph keep things choppy. The energy climbs a bit (667) but the surf is still borderline.

Friday the 11th through Monday the 14th is a real lull. Knee to waist-high, mostly SW swell, but periods drop to 8-15 seconds, and the wind stays cross-onshore from the south. The energy levels sink into the low hundreds (239-304). This stretch is poor, with light wind ripples and gentle chop. Honestly, not worth paddling out unless you just want to sit on your board.

We see a slight improvement mid-week. Tuesday the 15th has a tiny 2ft onshore SW swell, but Wednesday the 16th shows 3ft from the SSW, period 17 seconds, with onshore southwest winds at 6 mph. Still messy, but energy is moderate (465). The wind is blowing straight onto the waves, so it’ll be bumpy. Thursday the 17th morning has a 3ft SSW swell with a great 16-second period and almost glassy conditions (3 mph WSW winds). That’s a window of cleaner surf, but it’s still small.

The real standout is Monday the 21st of September morning. We get a 3ft SW swell with a 17-second period, light SSW winds at 6 mph coming straight onshore. Combined energy is a solid 634. It’s still onshore, but with that energy and long period there’ll be some shape if you can find a clean peak. This is an advanced reef and point break that is super consistent and always crowded, so expect a full parking lot. That Monday morning session is your best shot in this whole outlook.

After that, the final few days (22nd to 24th) drop back to marginal with 3-3ft swells and cross-onshore winds again.

So, truth is: it’s a lean 16 days. The first week is mostly a washout. The second week has a couple of windows, but nothing firing. Best advice: aim for Monday the 21st morning at Trestles (Uppers) if you can. It won’t be epic, but it’s the cleanest you’ll get.
