The Rock-Costa Azul Surf Forecast and Surf Report

Alright, Rusty here, let's get into it. We've got a solid window of surf coming up at The Rock-Costa Azul. This is a reef break that's known for being consistent and exposed to the south swell, and it really fires when that swell direction lines up with its optimum from the south, which we're seeing plenty of.

The water is running a very unusual 87°, which is a whopping 5° warmer than normal for this time of year. That's proper tropical bathwater and a real treat.

The combined wave energy (471) is moderate to start, building into strong territory later on. We're looking at a long-period groundswell from the southwest, with periods around 14 to 16 seconds, meaning those waves will have some serious shape and push. Because it's a reef break, this long-period stuff will wrap in beautifully, giving you those clean, racy lines.

Friday the 11th kicks things off in the afternoon. It's a risk of thunderstorms, but the wind is a gentle offshore from the west at 9 mph, keeping the 3 ft SW swell clean. It’s a bit touchy with the weather, but the surf is there.

Things clean right up for Saturday the 12th. Morning is dead glassy with a light SSE breeze at 3 mph and 3 ft of clean SW swell. The afternoon goes completely calm, with zero wind and glassy conditions on the same 3 ft swell. This is as good as it gets for a small-wave session.

Sunday the 13th keeps that glassy theme going in the morning with 2 ft of SW swell and a slight SE breeze. The afternoon sees a cross-offshore breeze from the WSW at 9 mph, keeping it clean but with a bit of texture.

Monday the 14th morning is a bit messy with a cross-onshore wind from the east and a risk of storms, but the afternoon goes calm and glassy again on a 2 ft swell that has jumped to an 18-second period. That's a lot of period for such a small wave, meaning very clean, slow lines.

Tuesday the 15th is average in the morning with a cross-onshore breeze, but the afternoon offers a clean 2 ft wave from the WSW cross-offshore wind. The energy is building, hitting 566.

Wednesday the 16th is where it starts to get really good. The morning is glassy with a 3 ft SSW swell and a 16-second period. By the afternoon, it's 4 ft with a 15-second period and a light cross-offshore breeze. Wave energy is up over 600 now, and the quality is dialed.

Thursday the 17th is a standout. The morning is absolutely glassy with 3 ft of SSW swell and a slight southerly breeze. The afternoon is a clean cross-offshore with the same size and a slight breeze. The wave energy is now 742, and the wind is perfect. This is the pick of the week. The swell direction is spot on for the optimum south-southwest.

Friday the 18th gets interesting. The morning is a bit crossed up, but the afternoon delivers a clean 2 ft wave from the SW with a massive 19-second period. The energy is still at 625. That long period is going to make for some very long, peeling lines over the reef.

The quality continues through the weekend and into the following week. Saturday the 21st and Sunday the 22nd both offer 4 ft to 4 ft of clean SW swell with glassy conditions. The energy is peaking again at 931. This is another top-tier period.

The second half of the run from the 22nd onward still has plenty of clean surf, mostly in the afternoons with a cross-offshore wind and 3 ft to 4 ft of swell, but the mornings get a bit more crossed up until the very end. On Saturday the 26th, we close out with a glassy 3 ft swell in the morning and a completely calm, glassy afternoon with a 2 ft wave but an 18-second period. A nice, clean wrap-up.

That said, the absolute standouts are Thursday the 17th for its flawless morning glass and strong groundswell, and the Sunday the 20th and Monday the 21st for the peak in wave energy (931) with perfect glassy conditions. Those are the sessions you want to clear your schedule for.

This break is a reef, so it's best suited for intermediate to advanced surfers, and it can get crowded often, especially on the good days. For the size we're seeing (mostly 2 ft to 4 ft), it's fine for confident beginners on the smaller days, but when it pushes 4 ft on the reef, respect the place.

Rusty.
