The Rock-Costa Azul Surf Forecast and Surf Report

Alright, Rusty here, let's talk about what's cooking at The Rock-Costa Azul. It's a solid, exposed reef break that's advanced-level only and handles a south swell real well.

The water is seriously warm right now, coming in at 89°, which is more than 5° warmer than normal for this time of year. You'll be surfing in boardies for sure.

We've got a good run of surf coming, but it starts off small. Wednesday morning the 26th is only showing knee to waist high swell from the SW, with a combined wave energy of (401). The wind is light cross-onshore, so it's not great, but not terrible. The real action kicks off on Wednesday afternoon when the wind switches to a light cross-offshore. The swell is still only around 3 ft, but it's clean and the energy bumps up a bit (410).

Thursday the 27th is better again. The morning is still a bit junky with cross-on wind, but the afternoon is where it's at. We get a clean 2 ft swell from the SSW with a long 18-second period—that's proper groundswell. The wave energy is good (564), and it'll be a classic reef setup with those long lines. This is a standout window for the mellow but quality stuff.

Friday the 28th pushes into the fun zone. Morning starts with 4 ft from the SSW, but the wind is side-shore. The afternoon is the best of the day: 5 ft SW swell with a 17-second period and a clean cross-off breeze. The energy is pumping (1312). This is a top pick.

Saturday the 29th keeps the swell running at 4-5 ft, with the afternoon session seeing clean waves and moderate wind. Sunday the 30th gets a bit bigger, hitting 6 ft. The wind is side-shore in the morning and cross-off in the afternoon, so the surf will be a bit more powerful and lumpy.

Monday the 31st has a fun afternoon on the horizon. We get 6 ft from the SW with clean, light cross-off wind (energy 856). The morning is a write-off with onshore wind and rain.

Now, the second week from September 1st has some promise. Tuesday the 1st looks iffy in the morning, but the afternoon is firing for experienced surfers: 5 ft SW swell, light cross-off wind, and energy (1034). Wednesday the 2nd is similar—morning is junk, but the afternoon offers 5 ft from the W, clean and glassy. That's a solid day.

Thursday the 3rd has a 4 ft morning with a super long 18-second period, but the wind is onshore. The afternoon gets a little messy with cross-on wind. Friday the 4th is the big one for the second week. The afternoon pumps up to 8 ft from the SSE with a huge energy reading (3155). But, the wind is a moderate cross-onshore, so it'll be choppy and messy. That size is expert territory only.

Things go downhill from there. September 5th, 6th, and 7th are blown out with risk of thunderstorms and strong cross-onshore winds. The swell drops back down to 3-4 ft. Not worth paddling out. The 8th and 9th have some small waist-high swell with clean-ish winds, but nothing to write home about. The run ends with the 10th being another messy, poor day.

The absolute standout windows are Friday afternoon the 28th of August for the best combination of size and clean conditions, and Wednesday afternoon the 2nd of September for that clean, glassy perfection.

Rusty.
