The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s cut through the noise and talk about what’s coming our way at The Rock-Costa Azul. This is a consistent reef break that handles a south swell beautifully, and we’ve got a decent run of waves on the horizon, though you’ll need to pick your moments.

The water is *much warmer than normal* for this time of year, sitting at 89.1°F with a whopping 6.8°F anomaly. It’s like the ocean forgot it’s almost September. The first real call to action is Tuesday morning, the 18th of August. We’ve got a solid 3.3ft swell from the SSW, with a long 14-second period pumping some real energy into the lineup. The combined energy is a solid 461 (moderate wave energy), and with a light cross-off wind from the SW at 6 mph, it’s going to be clean. This is a good one to kick things off.

Tuesday afternoon sees the swell tick up a bit to 3.6ft, still from the SSW, with a very long 15-second period. The combined energy jumps to 608 (moderate to strong). The wind is still cross-off, but there’s a risk of thunderstorms, so keep an eye on the sky. The surf is still there, but the afternoon quality is a bit more marginal.

Wednesday the 19th is a fade. The morning is a bit crossed up with a cross-shore wind, and the swell drops to 3.0ft with a 14-second period. The afternoon kicks up a moderate breeze at 12 mph, but the wind is cross-off, so it stays clean. The energy is still there at 372 (moderate), but it’s not as good as Tuesday.

Thursday the 20th is a mixed bag. The morning has a light offshore wind from the ESE at 6 mph, but the swell is down to 3.0ft with a 13-second period, and the energy is 344 (moderate). The afternoon looks better with a clean cross-off wind and a 2.6ft swell, but the energy is still moderate at 391. It’s surfable, but nothing to write home about.

Friday the 21st is small. The swell drops to 2.3ft with a 13-second period. The morning has a light offshore, but the energy is weak at 216 (moderate-low). The afternoon is clean with a cross-off wind, but it’s a small wave day.

Saturday the 22nd is a bit of a write-off. The morning is poor with an onshore wind, and the swell is 2.6ft with a 16-second period, but the energy is 395 (moderate). The afternoon is crossed up with a light cross-shore wind. Not worth the paddle.

Sunday the 23rd is a slow rise. The morning has a gentle cross-shore breeze and a 3.0ft swell with a 14-second period. The energy is strong at 627 (moderate to strong). The afternoon sees a 3.6ft swell from the SSE with a shorter 10-second period, and a moderate cross-off wind. The energy is 665 (moderate to strong). It’s a bit of a messy rise, but there’s something there.

Now, Monday
