The Lowdown
Alright folks, Rusty here with the full 16-day look for Trestles (Uppers). It’s looking pretty quiet out there, no real fire in the water. We’ve got small, weak swell running, so get ready for a flat spell.
Right now and into the middle of the week, we’re dealing with tiny waves. Swell is coming from the SW around 2ft to 2ft with periods that are way too short to push any real shape. The wind’s coming from the SW and WSW, mostly cross-on or onshore at 6 to 9 mph, so it’s bumpy and messy. The water temp is sitting at a super unusual 75°, which is *much warmer than normal* – feels more like summer bathwater.
The combined wave energy is between 241 and 399, which is moderate but with these short periods, those are weak, disorganised lines. Honestly, it’s a no-go. If you’re paddling out, you’re doing it for the tan.
Thursday August 13th things just scrape in as marginal. Morning might offer a tiny window with a light breeze – still small SSW swell at 2ft but a period of 16 seconds gives it a touch more life. Energy’s up to 343 but it’s still borderline at best. Wind is light, so it might have a clean face, but you’ll be hunting for waist-high runners.
Friday August 14th the morning stays clear and the swell (SSW) ramps up a little, with a period of 18 seconds. Combined energy jumps into the moderate range at 551. Again, it’s onshore wind until the afternoon, so not ideal. The morning might offer the cleanest window with a light breeze before the wind swings cross-onshore.
Saturday August 15th is your standout near-term call, but don’t get too excited. The swell picks up to about 4ft out of the SSW with a 16-second period, and the combined wave energy hits 731, the highest in this stretch. The wind goes cross-shore from the WNW in the afternoon with a light breeze – that’s *cleaner* than anything else on offer. This is the one day that might actually give you a wave face with a little push and less chop. It’s still small, but it’s the best we’ve got. Crowds are always an issue at Uppers, so you won’t have it to yourself. The long period (16 seconds) means the sets will be longer apart, but with that cross-shore wind, the point should break better than a beach.
Beyond that, the second week is all small and average. From Monday August 17th right through to the end of the window, we’re stuck in a rut of 1ft to 3ft swell, mostly short period, and cross-on shore breezes. Combined energy drops right back down to the 172 to 390 range. The waves are there on paper but it’s weak and choppy – better for a paddle float than a surfboard. There’s nothing worth getting up early for.
Honest truth, the best bet is Saturday August 15th by a long shot, and even that’s just “not terrible”. The rest is a flat, bumpy slog.
Catch ya,
Rusty
