The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a long stretch ahead, but don’t go paddling out just yet—this one’s a slow burn.

Right now, the surf is pretty flat and unexciting. We’re looking at a real gap here. The first few days are all about small, weak swell with poor conditions. It’s going to be a quiet start, so save your energy. The real action doesn’t start to show up until the tail end of the month and into September.

Let’s talk about the standouts. The best of the whole run is shaping up for Thursday, 3rd September and into the first weekend of September. Those days are the ones to circle. The morning of Friday, 4th September has a solid 4ft swell from the SSW, with a period of 19 seconds—that’s a proper long-period groundswell, packing a lot of energy (1281). Wind is light from the SSW, cross-on, but light enough to keep things fairly clean. The Saturday, 5th September morning keeps that same 4ft SSW swell, with a 16-second period and light wind from the SSW, now straight onshore—but that’s clean, glassy conditions. That’s the real gem. The combined energy is strong (1127), and the water is a touch warmer than normal for this time of year, sitting at 71°F, so it’s a nice treat.

Because this is a longer-period swell, it’s best on a point break like Trestles (Uppers)—it’s a reef and point setup, very consistent, and the optimum swell direction is from the W, but the SSW direction is still going to work. It’s exposed, so it’ll pick up the energy. Just be ready for crowds—it’s always busy there, so you’ll be sharing the lineup.

Now, the wind is mostly light through the second week, but the swell size stays around 3ft to 4ft, so it’s not an expert-only setup. The period drops off a bit later, but still offers decent waves. The 21st of August to the 25th is a write-off—tiny surf, poor conditions, and not worth your time. The 26th and 27th have a bump in size (5ft) but the period is short and the wind is cross-on, so it’s choppy and messy—more of a kite-surfing day than a paddle surf session.

Overall, the first week is a dud, but the second week delivers. The standout window is the 3rd to 6th of September—especially the morning of the 5th. That’s your best bet for clean, punchy waves. Don’t expect perfection, but it’s the best on offer.

Rusty.
