The Lowdown
Alright folks, it’s Rusty here, and I’ve got a long look at the waves coming up for The Rock-Costa Azul. This is a reef break that really needs a specific swell direction to light up, and we’ve got a solid run of Southern Ocean energy heading our way. The water temp is sitting right around average for this time of year, so nothing weird there.
We kick things off this Saturday, the 29th of August, with a nice pulse of swell. The morning is looking sweet with a 5ft SSW groundswell, a very long 16-second period, and a gentle cross-off breeze. The combined energy is pumping hard at 1306, so there’s a lot of grunt in the water. This is excellent surf for experienced surfers, but that long period means the sets will be a bit spread out. The afternoon sees the wind pick up a bit, making it a little more challenging, but it’s still clean.
The real standout for the whole window is Sunday morning, the 30th of August. The swell jumps to 6ft from the SSW, still with a solid 14-second period, and the wind goes glassy from the SSE. That’s a magic combo. The waves will be clean, powerful, and well-shaped. The combined energy is a hefty 1131, so this is not for beginners. This is the session to circle on your calendar. Afternoon has a risk of thunderstorms, but a light offshore keeps it clean.
Monday the 31st sees the swell drop a touch to 4ft, but we’ve got glassy conditions again in the morning. Still a good, clean option for a longboard or a fun mid-length.
The start of September brings a bit of a lull. Tuesday and Wednesday the 1st and 2nd see smaller swell and tricky winds. The best of that stretch is Tuesday afternoon, where a 2ft SW swell with a very long 18-second period and a light cross-off wind creates some glassy, clean lines. It’s small, but the quality is there for a reef break.
We get a big spike in energy and size around Thursday the 3rd and Friday the 4th, with the swell hitting 8ft on Friday morning. However, the wind is lousy – cross-onshore and choppy. That much swell with that much chop is a mess. The combined energy is over 2000, which is huge, but the wind completely ruins it. This is more of a kite-surfing setup than a good paddle surf.
The outlook cleans up nicely from the 5th of September onwards. Saturday the 5th is a bit bumpy, but Sunday the 6th of September is another top pick. We have a 4ft SSW swell, a 15-second period, and a light cross-off in the morning, switching to a clean offshore in the afternoon. The combined energy is 807 – moderate and well-organized. That’s a full day of clean, rippable waves.
The following week from the 8th through the 12th of September is all about small but clean conditions. The breeze is light, often glassy, with waves around 2ft to 4ft. The long periods (16-19 seconds) will give them a bit more push than you’d expect. Thursday the 10th and Friday the 11th look particularly glassy and inviting. The 12th of September has a risk of storms, but the afternoon cleans up with a 2ft SSW swell and a very long 19-second period, which could be a fun little session.
So, the best bets are Sunday morning the 30th of August for the biggest, cleanest conditions, and Sunday the 6th of September for a full day of clean, consistent surf.
Rusty.
