The Rock-Costa Azul Surf Forecast and Surf Report

G’day, Rusty here. Let’s talk about what’s coming up for The Rock-Costa Azul. This is a consistent, exposed reef break that loves a good south swell, and it’s going to be a busy stretch with some real highlights if you pick your moments.

The water’s sitting at 82°, which is about 5° warmer than normal for this time of year—that’s way above average, feels like a bath. You won’t need a wetsuit, just board shorts and wax.

The week kicks off on Friday, July 3rd, but the morning's a bit average—cross-on breeze from the SE with 3ft SSW swell and moderate energy (502). The afternoon cleans up nicely though: a light cross-off from the SW, same 3ft swell, but the energy picks up (621) and it’s clean. That’s the first real session window.

Saturday the 4th is similar—mornings are average with a cross-on breeze, but both afternoons offer clean conditions. Saturday afternoon sees 3ft of 18-second groundswell from the SSW, energy at 771—that long period will push through nicely at this reef.

Sunday the 5th is sneaky good. Morning has 4ft swell with 16-second period, energy 892, but it’s cross-on. The afternoon though—same 4ft, 16-second swell, clean cross-off wind—that’s your first standout. Smooth, lined-up waves, perfect for an advanced crew. This is a consistent spot for experienced surfers, and crowds are often here, so expect some company.

Monday the 6th delivers the goods. Morning is already fun with 4ft SSW swell and strong energy at 1244, but the afternoon? 3ft of 20-second groundswell, energy 1162, clean cross-off wind. That’s a very long-period groundswell—it’ll wrap right into the reef with power and shape, but it might break a bit straight at the ends. Best for the experienced crowd.

Tuesday the 7th pushes up to 5ft–5ft in the afternoon, 18-second period, energy spiking to 1539. That’s solid, powerful swell. The wind stays clean cross-off. This is expert territory—too much punch for beginners. Magic for those who can handle it.

Wednesday the 8th holds 4ft–5ft, still strong energy (1117–960), but the afternoon cross-off is clean. Good, but not the standout.

Thursday the 9th to Saturday the 11th is a bit of a lull—swell drops to 4ft–4ft, wind gets messy with cross-onshore or cross conditions. Still rideable, but nothing special.

Sunday the 12th to Monday the 13th sees smaller 3ft–3ft swell, but Monday afternoon cleans up with a cross-off—nice for a cruisy session.

Tuesday the 14th is interesting: 2ft SW swell at 18 seconds, but the morning has a light offshore—glass! That’s rare here. Clean, lined-up little waves for a quiet paddle.

Wednesday the 15th is poor in the morning—2ft onshore junk. Afternoon picks up to 2ft but cross.

Now, here’s the real standout—Friday the 17th. Morning has 7ft S swell at 9 seconds, energy 815. That’s a short-period swell, so a bit bumpy. But the afternoon? 7ft S swell with a 10-second period, light cross-off wind from the SW, energy 963. That’s big and clean—expert-only size and power. If you’re skilled, that’s the session to circle on your calendar. The best on offer in the whole outlook.

Saturday the 18th drops back to 2ft—don’t bother.

So overall, the standouts are Sunday the 5th afternoon, Monday the 6th afternoon, and Friday the 17th afternoon. The 17th is the biggest and best, but you need to know what you’re doing. The water is warm, the reef works with SSW swell, and the wind plays ball often enough. Get out there.

Rusty.
