Coxos Surf Forecast and Surf Report

Alright, Rusty here, and we’re looking at Coxos. This is a reef setup that needs a very specific window to come alive, and over the next 16 days, there’s one very clear, very good moment to be in the water, and it’s coming right up.

The overall story is a long stretch of messy, onshore slop, but it kicks off with a genuine standout. The water temperature is sitting around 68°F, which is basically average for this time of year, so nothing wild there.

The pick of the window, and really the only time to get excited, is Friday morning, the 28th of August. We’ve got a solid groundswell running at 8 ft out of the WNW, with a period of 11 seconds—that’s got some proper grunt behind it. The combined swell energy is strong at (1284), so you know there’s plenty of power. But the kicker is the wind: glassy. A light 3 mph breeze from the NNE is making it clean as a whistle. This is an advanced spot, and with that size, it’s not one for learners, but for the experienced crew, this is absolutely firing. The swell direction is WNW, and the optimum here is NNW, so it’s a little off the perfect angle, but with that quality it’s still the clear winner. The only note is that it can get crowded here, so expect some company on the peak.

From Friday afternoon onward, it turns into a bit of a write-off. That glassy window slams shut fast. Saturday morning the 29th is already cross-on and choppy, and that sets the tone. We go through a run of days—all the way into the first week of September—where the wind is relentless out of the N and NNW, 12 to 22 mph, just tearing the surface up. Swell hangs around 4 ft to 6 ft, but it’s all junk. The energy drops off hard too, into the hundreds (check 437, 195, 234), and the short 8 to 10 second periods just mean weak, wind-bumped lines.

There’s a tiny flicker on Thursday morning, the 3rd of September. Swell drops to 5 ft but the wind swings ENE at 6 mph, giving us a light cross-offshore that cleans it up. It’s a "clean" read. But the swell period is a short 7 seconds, so it’s not going to have any real shape.

Friday the 4th of September morning is flat and glassy, with a tiny 3 ft swell, energy down to (86) – weak. There’s a long period swell showing up on the Friday afternoon (14 seconds) but it's tiny at 2 ft and the wind goes onshore, so nothing doing.

The second week is rough. From the 5th of September through the 12th, it's a consistent run of cross-on winds, big lumps of swell, and poor conditions. The 9th and 10th of September see some serious size—10 ft from the NNW—but the wind is cranking 15 to 19 mph cross-on, making it a messy, blown-out mess. That kind of size with that wind isn't fun for anyone on a surfboard, and with this being a reef break, that setup looks way more interesting for kite surfing than paddle surfing. The energy is high (1347, 1284) but it’s all onshore junk.

The very last day in the window, Saturday the 12th of September morning, has a 3 ft groundswell from the W with a long 15 second period, and the wind is lighter, 9 mph out of the N. The combined energy is back up to (615). But it’s a cross-on breeze, so it’s still marginal. That said, that long period groundswell on a reef like this could surprise at the right tide, but it’s a punt.

So really, it’s a one-hit window. Get out there Friday morning the 28th for a few hours of glory, and then expect a long, frustrating wait until the next proper swell lines up.

Rusty.
