The Lowdown

Alright, let’s get into it.

The next stretch is a bit of a slow grind to start. We’re looking at a run of small, mostly marginal surf with light winds, but there’s a real pulse of energy showing up a little further out that could bring some proper head-high-plus waves. Right now, the opening days are pretty underwhelming—waist to chest-high at best, and honestly, a lot of it looks a touch lumpy or just not quite organized.

Looking at the first few days, Thursday and Friday (August 27th and 28th) are pretty weak. We’ve got light breezes in the morning, but the swell is small, around 2ft to 4ft, with a short period around 11 to 12 seconds. There’s some energy in the water—moderate at best, but it’s not doing much. The wind is light, but it’s cross-onshore, putting a bit of texture on the surface. Honestly, it’s a board-short board day, not something to get excited about.

The weekend (August 29th and 30th) brings a bit more size, but it’s still messy. Morning sessions look slightly better, with the swell pushing up to about 3ft to 4ft, and the period stretching to a more favorable 15 to 17 seconds. However, the wind is still light and mostly cross-onshore, so expect a few soft waves and some bump. The energy is building, though.

Now, Monday and Tuesday (August 31st and September 1st) are a real mix. Monday morning is small but has a clean offshore feel with the wind from the SW at 6 mph. That’s a bit of a tease, because Tuesday afternoon is where things start to click. We’ve got a glassy moment with a 3 mph offshore breeze from the north, light rain, and a 4ft S swell with a 12-second period. That’s the first window that looks genuinely clean, even if the size is modest.

Then comes the standout. Thursday, September 3rd is where the real action is. The swell jumps to 7ft from the SSW, with a 13-second period, and the combined energy is strong. The wind is light and offshore in the morning from the WSW at 6 mph. This is the pick of the whole window. At Trestles (Lowers) —that’s a break that’s very consistent and exposed to the SW—this is going to be a proper session. The direction matches the optimum, the period is solid, and the wind will be holding the waves open. This is the one to plan around. It’s big enough that it’ll be too much for beginners, but for anyone who knows what they’re doing, this is the standout.

Friday (September 4th) eases off a bit, dropping back to 4ft to 4ft with a 17-second period in the morning. Still a nice long-period groundswell, but the size is down. The wind is light from the WSW in the morning, so the early session should be clean, but the afternoon gets a touch bumpy with a 9 mph cross-onshore.

The following weekend (September 5th and 6th) is more of the same—around 3ft to 4ft, but the swell direction swings more to the SW, and the wind stays light and mostly cross-onshore. There’s still some rideable long-period energy, but the quality is not where it was on the 3rd.

From the 7th onward, it starts to fade. Monday the 7th has a little pulse with a 3ft SSW swell, but the wind is a bit stronger from the north, 9 to 12 mph, which actually cleans things up, but the size is small. Tuesday and Wednesday (September 8th and 9th) look poor—waves drop to 2ft to 3ft, the period is still long but the energy is weak, and the afternoon winds get stronger and cross-onshore. That’s pretty much a blank run right there.

The last few days (September 10th and 11th) tease us with a bit of hope—3ft swell with a 16-second period—but the wind is light and cross-onshore, and the energy is only moderate. It’s surfable, but nothing special. And that’s about it for the 16 days.

So, bottom line: if you can only paddle out once, make it Thursday, September 3rd. That’s the day. Big swell, clean wind, proper energy. The first week is small and marginal, and the final stretch fades out to nothing. There’s a gap of a few days in the second week where it really drops out, so don’t hold your breath for the 8th or 9th.

Stay stoked, but be picky. You’ll get one great day, and that’s worth it.
