The Rock-Costa Azul Surf Forecast and Surf Report

Alright, Rusty here, let's talk about the Rock.

We've got a solid run of swell coming through over the next couple of weeks. The standout is definitely the early weekend, with a pulse of strong, long-period groundswell that's going to light up this reef. The combined energy is massive, hitting 2369 on Friday morning, so there's plenty of power in the water. That's proper strong wave energy.

The water is sitting at 88°, which is a whopping 5° warmer than normal for this time of year. That's very unusual, and it's going to feel like you're surfing in the tropics.

Kicking off on Friday the 4th of September, we see a 7ft SW groundswell arriving with a 12-second period. The wind is a cross-on from the SE at 9 mph, which does put a bit of chop on the surface. It's a bit lumpy, but the power is there. Friday afternoon drops to 5ft from the SSW, period jumps to 16 seconds, and the wind goes cross-shore, cleaning it up a little.

But the real magic starts Saturday morning the 5th. The swell holds at 5ft from the SSW, still a very long 16-second period, and the wind goes super light. That's a big positive. By Saturday afternoon, the wind swings to a light cross-offshore from the WSW, making for clean surf at 5ft.

Sunday the 6th is the absolute gem of the whole forecast. We're looking at 4ft of SSW swell with a 15-second period, and the wind is forecast to be glassy in the morning. Dead calm. That's going to be as clean as it gets. The afternoon stays clean with a light offshore breeze from the NW. For a break like The Rock, which is a consistent reef (Costa Azul), this is when you want to be in the water. The swell is at a manageable size so it's not too big for a strong intermediate, but the quality will be top-notch. Expect it to be a bit busy, as this spot gets crowded often.

The combined energy drops through the week, into the 800-600 range, which is still moderate. Winds are a bit mixed, but there are moments of clean glass and cross-offshore conditions. The window for the best, cleanest waves this week is definitely Sunday morning.

Looking further ahead into the second week, the swell drops off significantly. From the 12th of September onwards, we're mostly looking at knee-to-waist high waves, 2ft to 3ft, with some very long periods. The 17th of September afternoon shows a 2ft swell riding a 21-second period, which is a very long period, but the size is tiny. The 19th of September afternoon has a cleaner 3ft from the SW. These are promising but far off, so less certain. Just keep an eye on the charts.

Rusty, signing off.
