The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here again. Let's talk about what's lining up at The Rock-Costa Azul. This is a top-notch reef break that loves a solid south swell, and we've got a nice run coming our way.

We're looking at a solid stretch of surf kicking off now. The water is a warm 88°, which is a solid 5° warmer than usual for this time of year – that’s much warmer than normal, so you can definitely leave the steamer at home.

The action starts this afternoon with a clean 4ft SW groundswell, a very long period of 16 seconds, and glassy conditions with a light air from the SSW. The combined swell energy is a moderate 809, and the setup looks really good.

The standout period is from Thursday the 10th through Saturday the 14th of September. Thursday afternoon is the absolute pick of the first few days – that 4ft SW swell with 16-second period and glassy wind is the perfect recipe for this reef. It’s an advanced spot so you’ll need your wits about you, and it can get crowded. The quality holds into Friday and Saturday, though the swell drops a touch and the wind shifts a bit, we still get plenty of glassy windows.

There’s a bit of a lull on Sunday the 14th with the swell dropping to 2ft, though it still has a nice 18-second period on Monday. Keep an eye on that Monday the 15th morning as the glass comes back. The surf then builds again into the following week.

From Monday the 16th of September, the energy starts ramping back up. By Wednesday the 18th, we’re seeing a very good quality 4ft SSW groundswell with a period of 15 seconds and clean conditions. The combined energy climbs into the strong range, reaching 860 on Friday the 19th.

The best of the entire outlook looks like Monday the 23rd and Tuesday the 24th of September. We get a consistent 4ft SW swell, 17-second period, and a string of glassy or clean offshore winds. The combined energy peaks at 932 on the Monday morning – that’s very strong, powerful surf that will absolutely reel down the reef. This is serious wave energy, so it's for experienced surfers only.

The swell holds through to the end of the window, dipping a little into the last few days with a 2ft but very long period 21-second SW swell on Friday the 26th. That’s a very long-period groundswell, which will break a bit straight at beach breaks, but here at The Rock it should line up nicely.

Overall, the next 16 days look promising. The near-term is reliable, and that late September push is something to keep a keen eye on, though it's a bit further out, so be ready for changes.

Rusty.
