Alright, Rusty here again, same story but in feet, miles, and Fahrenheit.
We’ve got a slow start at Trestles (Uppers), a reef and point break that’s very consistent and exposed to the west. The water’s about 68°, which feels a touch warmer than normal for this time of year.
The first several days are pretty weak. From Tuesday afternoon through the following Monday, the swell runs small, from 1 ft up to about 4 ft, mostly from the SSW. But the wind is cross-onshore or onshore nearly the whole time, making things choppy and messy. Combined energy stays low to moderate, and the swell period is decent (15–18 seconds), but the surface is ruined. Not worth chasing.
Then we hit Saturday the 18th of July. That morning is the real standout. Winds go glassy – light from the west at 3 mph – and we get a clean 3 ft swell from the SW with a lovely 18-second period. Combined energy is moderate at 578. This is what you want at a point break like Uppers: smooth, lined-up, long-period groundswell with no wind texture. Sets will be spaced, but the waves will be good. This is the best of the whole run.
Sunday the 19th of July brings more size, with a S swell peaking around 5 ft and a 14-second period, combined energy jumping to 1482 – that’s strong energy. But rain showers and light cross-onshore wind keep it from being perfect. For the bigger-wave experts, it’s an option, but not clean.
After that, through Wednesday the 22nd, the swell drops back to small, messy conditions with onshore or cross-onshore wind. Nothing to plan around.
Bottom line: Saturday the 18th of July morning at Uppers – that’s the moment. Glassy, clean, good groundswell. Everything else is second-tier at best.
Rusty.
