The Lowdown
Alright, mate, Rusty here. Let’s break down what’s happening at The Rock-Costa Azul.
The surf is slow to start, so don’t bother paddling out on Friday or Saturday—it’s pretty average. Your first real chance is Sunday afternoon, the 19th of July. We’ve got a 3ft swell from the SSW with a very long 17-second period. The wind is a light cross-offshore, so it’ll be clean. The combined energy is 820, which is moderate, and the water is sitting at 85°F, which is much warmer than normal for July—over 5°F above average, so that’s pretty unusual for this spot.
Monday afternoon, the 20th, offers 4ft from the SSW at 16 seconds, clean again with a cross-off breeze. It’s still a bit marginal on paper, but the conditions make it workable. Tuesday afternoon, the 21st, bumps up to 6ft from the SSW, still with that clean cross-off wind. That’s a fun size.
Now, the standout. Thursday morning, the 23rd of July, is the one to pencil in. We’ve got 6ft from the SW, 12-second period, and the wind is glassy. That’s a rare combo—glassy at a reef break with a solid SSW swell. The combined energy is 1171 (strong), and it’s rated excellent for experienced surfers. It’s not a beginner wave at that size, but if you know the lineup, this is the session. The break is consistent and exposed to the south, so it’ll be handling that swell well. Crowds are often an issue, so get in early.
Looking ahead, Friday afternoon the 24th has a very long period 4ft SSW swell at 21 seconds, clean again but smaller. Saturday afternoon the 25th brings 5ft from the SW at 19 seconds, clean, and the energy jumps to 2316 (very strong). That’s a powerful swell, and the long period suits this reef. By Wednesday the 29th, we’re looking at 8ft from the SSW—that’s big, expert-only. The wind is cross-off and clean, but at that size, only the brave need apply. The energy reading is 3148, which is very strong.
After that, the swell fades into early August, with smaller, shorter-period waves and less favourable winds. The first week of August looks marginal.
Bottom line: Sunday afternoon (19th) is a nice warm-up, but Thursday the 23rd morning is the standout with glassy conditions and a solid groundswell. The weekend of the 25th–26th has size and power, but it’s for the experienced crew. The water is unusually warm, so ditch the wetsuit.
Rusty.
