Trestles (Uppers) Surf Forecast and Surf Report

Alright, this is Rusty, and I’m looking at the next 16 days for Trestles (Uppers). It’s a reef and point setup that’s very consistent, and it’s exposed to the west swell. The optimum direction is from the west, so we’ll be watching that.

Right now, it’s a bit of a slow start. The weekend kicks off Saturday morning, July 11th, with a small 3ft swell from the SSW. The water temp is sitting at 68°, which is about normal for this time of year. But the wind is a cross-on from the SSW at 6 mph, making it a bit bumpy. The energy is moderate (471). Not a great look for a paddle. Saturday afternoon, however, things get glassy. The wind drops to a WNW 3 mph, a slight air, and the swell eases to 3ft. The combined energy drops to 371, but with that glassy surface, it’s a much cleaner window. Those waves will be long period groundswell at 15 seconds, so they’ll have some punch and shape, but the sets will be a bit more spaced out. It’s a nice little window, but not a standout.

Sunday and Monday are pretty flat and messy with cross-onshore winds. The swell stays small, around 2ft to 3ft, and the period drops. The energy is moderate, but the wind is all wrong. You’re looking at poor surf conditions through the middle of the week. Tuesday the 14th is a write-off, with a tiny 1ft to 2ft swell and a 9 mph cross-on. The energy is weak (187). Wednesday and Thursday are marginal at best, with small waves and onshore wind.

Then we get a bit of a pulse on Saturday the 18th. The morning shows a 3ft SSW swell with a very long 18-second period, combined energy of 382 (moderate). The wind is onshore from the WSW though, so it’s a bit crumbly. It’s marginal, but the long period groundswell might offer a few clean lines if you’re patient.

The real standout for the whole period is Sunday, July 19th. The morning brings a solid 5ft swell from the S, with a 13-second period. The combined energy jumps to 1111 (strong). That’s a proper groundswell with some weight. The wind is onshore from the WSW at 9 mph, which isn’t ideal, but the swell size means there’s some grunt. The afternoon holds a 4ft S swell, with the wind backing to a lighter W 6 mph cross-on, keeping the energy at 902 (strong). This is the biggest swell of the forecast, and while it’s a bit on the bigger side for beginners, it’s a solid option for advanced surfers. Keep in mind, with a long period swell like this, the point break at Uppers will handle it well, offering longer, racier walls.

After that, the energy drops back to moderate levels for the rest of the week. The 23rd and 24th of July are small and weak, with 1ft to 3ft swells and cross-onshore winds. The energy is weak (117 to 243). There’s a little blip on the 25th with a 3ft SSW swell and a very long 20-second period, giving a combined energy of 734 (strong), but the wind is a cross-on from the WSW. It’s a waiting game for a clean window.

So, for the best bet, I’d put my money on the Sunday, July 19th window. It’s the biggest, most energetic swell of the whole 16 days. The other days are mostly small, bumpy, or marginal. If you’re feeling patient, that Saturday afternoon the 11th is glassy, but it’s small. The second week looks very quiet, with only a few marginal pulses. It’s a long-range call, so less certain, but that 19th is the one to circle on the calendar.
