Table - best surf conditions forecast for Trestles (Uppers) over the next 16 days.
Alright, here’s the same scoop but in old-school feet and miles.
First part of the run—pretty lean. Trestles is seeing small, sloppy surf through the first half of the month. The wind’s mostly cross-onshore with a southerly breeze, messing up the face, even when there’s a little pulse in the water.
Thursday the 9th: a 3ft SSW groundswell with a 16-second period. Sounds good on paper, but the SSW wind at 9 mph keeps it choppy. Combined energy is moderate at 634. Water temp is 68°, dead average for July.
Friday and Saturday are flat and poor—3 to 3ft, period dropping to 15 seconds, still cross-onshore. Not worth wetting a suit.
Sunday the 12th through Tuesday the 14th is tiny—3ft down to 2ft. The wind stays onshore or cross-onshore, sometimes gusty from the WNW at 12 mph Tuesday afternoon. That’s kite-surf junk, not paddle-surf. Wednesday the 15th afternoon—here’s a tease: glassy conditions with a light SSE breeze at 3 mph, but the swell is only 1ft. Pretty water, no power.
Saturday the 18th picks up a bit: 3ft from the SW with an 18-second period, but a W wind at 9 mph makes it lumpy. Energy gets to 588.
Now for the real deal. Sunday, July 19th. The morning serves up a 3ft S swell with a 20-second period—that’s long, clean groundswell. Combined energy jumps to 1134, moderate-strong. Wind is light from the W at 6 mph, cross-onshore but manageable. By afternoon, the swell hits 6ft from the S, period 16 seconds, energy rockets to 3018. Wind drops to 6 mph. The waves will have shape and punch—best of the whole 16 days. It’s expert territory, though, with that size and long gaps between sets.
Monday the 20th keeps the size—8ft in the morning, 7ft in the afternoon, both from the S. That’s big for most folks. Wind is light and variable, so the surface stays clean enough for those who can handle it. Energy stays strong.
After that, it fades back to 3ft by Wednesday the 22nd, and by the 24th we’re talking 2-foot slop with onshore wind. Not your day.
Best on offer: Sunday, July 19th at Trestles (Uppers). A solid S swell, long period, strong energy, and light winds making for clean conditions. Groundswell on a point gives you good shape but long waits between sets. Not for beginners, but for the experienced surfer, that’s the day.
