The Lowdown

Alright, it’s Rusty here. Let’s talk about what’s on offer.

Right off the bat, I gotta be straight with you – things are looking pretty grim at Trestles (Uppers) for the foreseeable future. This stretch is known for being very consistent, but the next week and a half is full of nothing but poor surf conditions and marginal calls. The swell is small, the wind is on it or cross-onshore, and it’s just not gonna be worth paddling out.

The combined swell energy stays weak to moderate for the whole first week, ranging from 128 to 735, which is better for a paddle than a proper wave face. The periods are short to moderate – between 13 and 18 seconds – so you’re not getting any real groundswell power here. The water temp is sitting around 75°F, which is much warmer than normal for this time of year, so you’ll be sweating in your wettie.

Now, if you’re desperate, there is a little something to look forward to. Monday afternoon, August 24th – that’s more than a week away – we get a tiny window of glassy conditions. Wind goes to 3 mph from the south-southwest, surf is still only 2 ft from the SW with a 17-second period, and the combined energy is low (224). It’s not big, but it’s the prettiest forecast in the whole run. The break is a reef and point setup, which handles that long period better than the beach, plus the optimum swell direction from the west lines up nicely. Expect crowds here though – this spot is always busy, so get there early if you want a clean one. Nothing else in the whole 16 days even comes close. The rest is a long stretch of junk.

There’s really no standout for experts or solid surf, and the lack of any bigger swell means it’s not even interesting for kiting. A long, flat run – but as consistent as this break can be, I wouldn’t bet on it staying this poor forever.

Rusty.
