The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Trestles (Lowers). This is a classic setup, beach and reef, very consistent, and it always draws a crowd. We’ve got a solid run of swell early on, but then we hit a long dry spell.
The action kicks off this Saturday morning, September 5th. The water is sitting at a toasty 74°, which is much warmer than normal for this time of year, so ditch the wetsuit if you've got the hide for it. The swell is a long-period groundswell from the SSW at 3ft, with a period of 16 seconds. That 16-second period is a beautiful thing – it means real energy, good shape, and those long lulls between sets. The combined energy is strong at 1040. The wind is light and cross-onshore though, so it's a bit rippled, and the overall call is marginal. Not the best start.
Now, Sunday morning, September 6th, is where you want to be. We’ve got a solid 6ft of S swell pushing in at 14 seconds, with the combined energy climbing to 1272. The wind is offshore from the NNE at 15 km/h, and that makes all the difference. The surf is clean, the lines will be holding up, and the model is calling it excellent for experienced surfers. This is your standout. Expect a crowd, because it’s always busy here, but for a good reason. The swell direction is a touch south of the optimum SW, but with that offshore wind, it’s going to be a hell of a session. Sunday afternoon stays clean too, with a 5ft S swell and light NNW cross-offshore breeze.
Monday the 7th gets messy. The swell bumps up to 6ft from the SSW, but the wind swings around to a moderate WNW cross-shore, chopping it up. That’s kite-surfing territory, not paddle surfing. The rest of the week and into the next just fades out. By Tuesday the 8th, the swell is already dropping, and the wind is on it. From Wednesday the 9th all the way through to Sunday, September 20th, the surf is small, weak, and mostly blown out. The period hangs around, but the height drops below 3ft, and the energy dips into the 200-500 range. There are days with clean, onshore winds, but the swell is just too small to get excited about.
So, the story is simple: if you can get out Sunday morning, September 6th, you’re golden. After that, it’s a long, flat gap for nearly two weeks. The models show a tiny pulse trying to pop up around the 20th, but it’s still marginal. Keep your eyes on the forecast, but for now, make that Sunday session count.
Rusty.
