The Lowdown
Alright, grab your board, let's talk about what's cooking at The Rock-Costa Azul.
First up, the water is a scorching 89° right now, which is much warmer than normal for this time of year, so you can leave the steamer at home.
Honestly, for the next week or so, it's a bit of a slow grind. We've got small, inconsistent swell hanging around, but nothing that's gonna get the heart racing. The wind is a bit of a fiddle too, so don't expect perfection.
The better windows are the afternoons. Wednesday the 19th and Thursday the 20th both have clean afternoon surf, with a light cross-offshore breeze and a clean 3 ft of SSW swell. It's not huge, but it's rideable. The wave energy is moderate – around 370-390 (combined energy of all swells directed here) – so there's enough push for a fun session.
Friday the 21st afternoon shapes up nicely with a clean 2 ft of SSW swell and offshore wind, making for some tidy little waves. That's a good sneaky session.
Now, look a little further ahead. The real standout is Friday the 28th of August. That afternoon we're looking at a solid 5 ft of SSW groundswell, with a 17-second period. That's proper, long-period energy. The wind is a light cross-offshore, keeping it clean. This is excellent surf for experienced surfers, and the wave energy is strong (1430). That's the one to circle on the calendar.
Saturday the 29th of August morning is also a beauty, with a 6 ft of SSW swell, again with a 16-second period and clean conditions. This is expert-level stuff, but it's going to be pumping. The energy is very strong (1452).
There's a bit of a lull after that, and then around the 3rd of September, the swell bumps up to 8 ft, but it's accompanied by strong onshore winds and rain, so it's a messy, blown-out affair. That setup looks more interesting for kite surfing than paddle surfing.
So, to sum it up: the afternoons this week are your best bet for a fun, clean wave. For the real deal, lock in the afternoons of Friday the 28th and Saturday the 29th of August for some serious swell.
