The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here. We got a 16-day outlook for The Rock-Costa Azul, and it’s a wild ride. This reef break is exposed to the swell and handles southerly groundswell properly, but we’re looking at a real mix of conditions. The water is sitting at a balmy 88°, which is way warmer than usual for this time of year – feels like the tropics.

Right off the bat, Monday the 31st is small and so-so. Morning has a 3ft SSW groundswell with a solid 13-second period, but the wind is a light cross-shore, and the combined wave energy is moderate (555). It’ll be a bit bumpy. The afternoon drops to 3ft but turns clean with a cross-offshore breeze. It’s not going to blow you away, but it’s something to get wet on.

Tuesday the 1st of September is poor. Morning is cross-on with a tiny 3ft swell, and the afternoon is a messy cross-shore wind on a 2ft SW swell with a very long 18-second period. That long period will make it straighten out and be tough to ride.

Then things get heavy. Wednesday morning the 2nd has an 8ft southerly swell with a short, dumpy 12-second period and strong onshore winds – total write-off. The afternoon is the same size but with a lighter cross-on wind. Still, it’s big and messy. The combined energy is already strong (2077 and 2251).

Thursday the 3rd and Friday the 4th are for experts only. The swell jacks up to 10ft from the south and SSW, with strong wave energy (2632 up to 4629). The wind is cross-on and onshore. It’s way too big for most and just a choppy, heavy mess. Saturday the 5th and Sunday the 6th stay around 8ft from the southwest, but we finally get some decent windows. Saturday afternoon goes cross-offshore and clean, and Sunday the 6th is a real standout. Sunday morning has an 8ft WSW groundswell with a 12-second period and a clean cross-off breeze. The afternoon turns pure offshore from the WNW with the same size. This is serious, powerful reef surf for experienced surfers – solid energy (2538 and 2346).

Monday the 7th is your best bet if you aren’t looking for a beating. The swell drops to a much friendlier 5ft from the west, 11-second period, and it goes glassy in the morning with only moderate energy (1061). The afternoon stays clean with a cross-off breeze and a 5ft swell. That’s a proper session.

Tuesday the 8th and Wednesday the 9th are small but glassy. The 9th afternoon is a beauty – 3ft SW swell with a very long 17-second period and dead calm wind. It’ll be sheet glass, but that long period at a reef will produce some long, walled-up waves. The energy is moderate (618).

Thursday the 10th and Friday the 11th are consistent and clean. Friday morning the 11th is a gem: 4ft southerly swell, 12-second period, glassy conditions, and moderate energy (792). That’s a great combo.

Saturday the 12th has a fun 6ft SSW swell in the morning with clean conditions and solid energy (1288) – a great day for experienced surfers.

Sunday the 13th sees another massive pulse: 10ft SW swell. Morning is glassy, afternoon is offshore. This is huge, powerful reef surf. Only for the brave. But here’s your second standout: Monday the 14th. The swell drops to a manageable 7ft from the west, 11-second period, morning is glassy with strong energy (1447). It’s still big, but the conditions are perfect for experienced surfers.

The last few days, Tuesday the 15th, trail off into small, clean, glassy 2ft SW groundswell with a very long 16-second period. Nice for a log or a fish, but nothing to get worked up about.

Overall, the standouts are Sunday the 6th and Monday the 14th. Sunday the 6th offers the best combo of big swell, offshore wind, and power for experts. Monday the 14th is a bit smaller and glassy, making it the most user-friendly of the bigger days. The crowds can be an issue here, and with conditions this good, expect some company.

Stay safe out there.
Rusty.
