The Lowdown
Alright folks, Rusty here. Let’s take a hard look at what’s on the table for Trestles (Uppers). It’s a reef and point setup, very consistent, and it likes the west swell. Normally a gem, but the next couple of weeks look like a tough stretch.
The first ten days or so are looking pretty grim. There’s not much energy and the wind just won’t play ball. We’re seeing a persistent cross-onshore breeze from the southwest, which is messing with the surface. The water temp is sitting at a very unusual 75°, which is about 7° warmer than we’d expect for this time of year—that’s a big anomaly right now.
We have a long gap here. Don’t expect anything worth paddling out for from Thursday the 13th of August all the way through to Monday the 24th of August. The best you’ll see in that stretch is maybe a Saturday afternoon (15th August) with a small 4 ft swell from the SSW, but with a light cross-onshore wind, it’s just going to be tiny and rippled. Combined swell energy (677) is moderate but the quality is shot.
The only real standout window shows up later. We’ve got a pulse of energy arriving Tuesday the 25th of August. The afternoon is the pick of the whole 16-day run. We’re looking at a 5 ft swell from the south, with a period of 14 seconds. That’s a proper groundswell. The wind is forecast to be light and onshore from the SW at only 6 mph. For a point break, that long-period south swell should wrap in nicely and give us some decent shape. Combined energy jumps right up to a solid moderate (1043). It won’t be huge, but it’s the cleanest wave we’re going to get. It’s still only marginal, but that’s the best of a bad bunch.
The following Wednesday morning (26th August) hangs in there with a 3 ft south swell and light onshore wind, offering another chance for a few. After that, it's back to choppy, cross-onshore junk.
So listen, don’t get your hopes up for the first week and a half. Focus on Tuesday the 25th of August afternoon if you can. It’s the one day where the pieces nearly come together. This is a long-range call though, so keep an eye on it.
Rusty.
