The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking for the next couple of weeks.

We’re starting off with a pretty quiet spell. The first few days are looking flat and messy, so don’t get your hopes up for the weekend. The first real chance to get wet comes on Monday the 7th, but it’s small. We’ve got a tiny 1ft swell from the WNW, but the wind is a clean cross-offshore breeze, so the surface will be smooth. It’s really just a knee-high dribbler for the patient.

The build-up starts on Thursday the 10th. That’s when things get interesting. The morning sees a 2ft SSW swell with a nice long period of 17 seconds—that’s a proper groundswell. The combined energy is moderate at 261, and with a light offshore breeze, the waves will be clean and lined up. This is the standout period for the whole outlook. The wave shape and consistency will be much better than anything before it. The water is sitting at a balmy 70°, which is much warmer than normal for this time of year, so you might even be able to ditch the thick wetsuit.

The best spot to focus on is Rincon - Rivermouth. It’s a point break that loves a WNW swell, and this long-period SSW groundswell will wrap in nicely. The combination of that clean offshore wind and the long period means the waves will have plenty of push and shape. The tide will be a factor here, so watch the bank. This spot gets crowded often, so get there early for a peak.

Saturday afternoon the 12th sees a jump in size to 6ft from the WNW, but the period drops to 7 seconds and the wind goes cross-on. That’s a short-period, bumpy mess. It’ll be fat and choppy, probably more fun for the kite crew than a paddle surfer.

Sunday the 13th afternoon cleans up again with a 5ft WNW swell and a 6-second period, but the wind is back to that clean cross-off. The combined energy is a strong 303, so there’s plenty of juice in the water. The short period means it’ll be a bit dumpy, but for a bigger, punchy beach break wave, it’s worth a look for experienced surfers. Beginners should steer clear.

The rest of the second week gets smaller and the wind stays mostly cross or cross-off, keeping conditions clean but the surf marginal. The 14th and 15th see waist-high waves with okay shape, but nothing to write home about. The 18th and 19th have a tiny 2ft to 2ft SW swell with a long period, but the wind is mostly cross-on, making it a bit of a struggle.

Honestly, the best call is Thursday the 10th and Friday the 11th. The swell is modest but the quality is there. The long period, the clean wind, and the warmer water all line up. The rest of the window is mostly small or short-period junk. Get it while it’s good.

Rusty.
