The Rock-Costa Azul Surf Forecast and Surf Report

Alright, Rusty here, let’s talk about what’s cooking at The Rock-Costa Azul.

First thing you need to know, the water is sitting at 86.5°F, which is much warmer than normal for this time of year. That’s a good five degrees Fahrenheit above what you’d expect, so if you’re paddling out, you might not even need a spring suit.

The coming week and a half starts off a bit flat. The first few days are a write-off, with tiny swell and poor surf conditions. Tuesday the 4th and Wednesday the 5th are not worth your time. But look, we’ve got a solid run of activity building from Thursday afternoon, the 6th, with a 2.3ft SSW groundswell and a period of 18 seconds. That’s a real long-period groundswell. The combined energy is moderate at 466, and with a gentle cross-off wind, it’ll be clean. That long period is best for a reef like this, so it’ll hold up well.

The standout in this whole run is Saturday afternoon, the 15th of August. We’ve got a 4.3ft SSW swell, period of 16 seconds, combined energy of 880, and a light cross-off wind from the SW. That’s clean, consistent, and the reef will be working. It’s an advanced wave, so it’s not for beginners, but for the crew that knows this place, it’ll be the best session of the window. The crowd factor is “often” so expect some company.

Another good one to mark is Monday afternoon, the 10th of August. A 2.3ft SSW swell, 19-second period, and combined energy of 612. That’s very long period, so the reef will shape it up nicely. The wind is cross-off, clean, and the forecast says “very good surf conditions.” It’s a smaller wave, but the quality will be there.

Towards the end of the run, Thursday afternoon the 13th and Sunday afternoon the 16th both look promising with 3.0ft and 3.9ft SSW swells, combined energy in the 600s, and clean cross-off winds. The 16th has a 3.9ft swell, 15-second period, and 647 energy – that’s a solid, fun afternoon.

There’s a gap of no real surf from the start until Thursday afternoon the 6th, so don’t rush out early. The real meat is from the 10th onward, with the 15th being the pinnacle. The morning of the 14th has a big energy spike of 1177, but the wind is onshore from the ESE, so it’s a mess. The afternoon of the 14th has a 4.6ft SW swell, 17-second period, and 1286 energy, but the wind is cross and light, so it’s marginal. That’s a lot of energy, but it’s not clean enough for a full recommendation.

Overall, the best call is Saturday afternoon, the 15th of August. Get on it.
