The Lowdown

Alright, folks. Rusty here. Let’s break down what’s happening for Trestles (Uppers).

To be honest, the next two weeks are a bit of a slow burn. The first week is a real struggle, with a lot of small, wind-affected junk. The light at the end of the tunnel is the second weekend and the start of the week after, which finally shows some clean, promising surf. The standout sessions look to be the morning of Saturday, July 26th, and the following Monday morning, July 28th.

The water is sitting at a very warm 71°, which is 5° warmer than normal for this time of year, so you’ll be comfortable in a shorty.

We’ve got a real gap to start. From Thursday, July 16th, all the way through to early on Saturday, July 19th, the conditions are just poor. We’re looking at tiny 1ft to 3ft swell from the SW with a long period, but it’s all cross-on shore wind. The energy is low, between 189 and 480 (combined energy), and the surf is choppy and messy. Not worth the paddle out.

We start to see a change on Saturday morning, July 19th. The swell picks up a bit, with a 5ft, 14-second S swell, but it’s still onshore. The wind is light from the SW, so it’s not totally blown out, but it’s still pretty marginal. The following Monday morning, July 21st, sees a 3ft, 16-second SSW swell with light offshore SW winds, but the overall energy is just 645 (combined energy). It’s a tease.

The real action, the standouts, start to show up around Saturday, July 26th. The morning of the 26th looks clean. We’ve got a 3ft, 19-second SSW ground swell, which is a very long period. This is a proper groundswell, but that long period means it might wrap a bit too straight for a beach break, but for a point/reef setup like Uppers, it’s prime. The wind is light offshore from the SW, so it’s going to be glassy and clean. The combined energy is a solid 1272 (combined energy). This is the best on offer in the whole forecast period. This spot is ‘very consistent’, so you can trust it’s going to be breaking. It’s an advanced break, but on this window, it’s going to be worth the paddle.

The next day, Sunday, July 27th, is also solid. The morning shows a 4ft, 18-second SSW swell with light offshore WSW wind, giving a combined energy of 1244. The afternoon is similar, with a 4ft, 19-second SSW swell, and even though it’s a touch cross-on, the light wind keeps it rideable. The morning of Monday, July 28th, is another standout. A 4ft, 17-second SSW swell, light offshore SW wind, and a combined energy of 1105. Clean, lined-up sets.

After that, the window closes. The end of July into August 1st, the swell drops back to 3ft to 3ft, and the wind turns cross-on again, so we’re back to poor conditions.

So, to sum it up: the first week is a write-off. The second week is where it’s at. Get your board ready for the morning of Saturday, July 26th, and Monday, July 28th. Those are the sessions to chase.

Rusty.
