The Lowdown
Alright, this is Rusty, and I’m looking at the long-range forecast for Trestles (Lowers). I’ll give it to you straight—this is a tough 16-day stretch to get excited about. The swell is hanging on but it’s coming in from the south-southwest, which isn’t the optimum southwest direction for this spot. Most of the time, the combined energy is weak to moderate—running between 200 and 500 for much of the run—and that just doesn’t cut it.
Right now through the first week, we’ve got small surf, mostly around 2ft to 3ft, with light onshore or cross-onshore breezes. It’s messy. The water temp is about average for this time of year, nothing unusual. The best glimmer comes on Saturday the 15th of August. Afternoon shows a glassy surface—wind goes almost dead calm—and the swell bumps to about 4ft from the southwest with a 16-second period. That long period suggests real push and shape, especially on a reef-and-beach setup like this. But don’t get too stoked—the rest of that weekend and into the next week gets chopped up again by wind, and the swell fades back under 3ft.
There’s a long gap of poor to marginal conditions before and after that Saturday window. From now until Friday the 14th, it’s basically a wash. Then after Sunday the 16th, the surf drops again and stays weak through to the end of the 24th.
Bottom line: if you’re going to paddle out, your best bet is Saturday afternoon, August 15th. Clean, waist-to-chest high sets, long period SW swell. But keep expectations in check—this isn’t a classic Trestles run. Crowds are always a factor here, but for that window the conditions might thin the pack a little. It’s the one standout in a long, quiet stretch.
