Cocles Surf Forecast and Surf Report

Alright, Rusty here, breaking down the Cocles forecast for the next couple of weeks. It’s going to be a mixed bag, so let’s get into it.

Right off the bat, this Saturday morning (September 12th) isn’t looking too flash. We’ve got a 4ft swell coming out of the NE at a short 8-second period, and with a cross-onshore breeze, the water’s gonna be a mess. The energy’s weak (206), and it’s just poor conditions. That afternoon isn’t much better, a bit bigger at 5ft but still messy.

Sunday (September 13th) sees the swell jump up. We’re looking at a 7ft to 7ft ENE swell with a 10-second period, so there’s some decent energy behind it (756 - moderate). The problem is, it’s still cross-onshore, and the surf is described as marginal. This is getting into the territory where beginners might start to struggle, but it's not quite expert-only yet. Keep an eye on it, but don't expect perfection.

Monday (September 14th) brings a 6ft swell from the ENE. The morning has some promise with a super light wind, but the “cross” wind state and a note of questionable tide conditions mean it’s not a green light. The afternoon gets chopped up again. The wave energy is moderate (576).

We hit a bit of a lull through Tuesday (15th) and Wednesday (16th), with swell dropping back to 4ft-5ft and energy falling. The winds stay on the wrong side of things. It’s frustrating, because the ocean has some push, but conditions are just poor. If you’re a beginning surfer, this chunk is less than ideal.

Now, here’s the standout window. Thursday morning (September 17th) is the first real glimmer of hope. A 5ft ENE swell with that consistent 9-second period, combined energy is a solid three-digit (415), and we get glassy conditions. That’s the key. A light NW breeze at 3 mph will smooth it right out. The surf report flags “expect good surf conditions” – that’s what we want to hear. This is your best bet for the whole outlook. The water temperature is about what you’d expect for this time of year, nothing to note there.

Friday morning (September 18th) looks similar. Glassy again, a 5ft ENE swell, and the same clean vibe. It won't be mind-blowing, but it’ll be fun and surfable. The afternoon turns onshore and gets messy again.

After that, it starts to fade. Saturday (19th) has a chance for a glassy afternoon with a 4ft swell, and Sunday (20th) morning is glassy but the swell drops to 4ft. By Monday (21st), we’re down to 3ft, and while it’s glassy, the energy is weak (109). The rest of the week into the 27th is a slow, fading grind with small, weak, and mostly poor quality surf. There’s a notable gap of several days with nothing worth recommending.

So to sum it up: the next few days are pretty average. The real window is Thursday the 17th and Friday the 18th mornings. Get out there when the wind goes glassy, and you’ll find some clean, head-high waves. But don’t hold your breath after that, because the ocean is going to sleep.

Rusty.
