The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming our way for the next couple of weeks.

Right off the bat, we’ve got a real mix of conditions. The overall pattern is a steady, long-period swell from the south-southwest, but it’s not a huge one. The water is sitting at 87°F with a water temperature anomaly of 5°F which is much warmer than normal for this time of year.

The first real standout is looking like Friday afternoon, August 14th at The Rock-Costa Azul. This is a reef break, so it handles a long-period swell well. We’re looking at a solid 5ft of swell from the SW, with a period of 17 seconds. That’s a proper groundswell. The combined energy of all swells directed here is 1236, which is strong – you’ll feel the power. What makes this a real winner is the afternoon forecast: glassy conditions. Zero wind. That’s rare and it’ll be clean as a whistle. It’s a session for experienced surfers, as the size and power will be too much for beginners. The break is consistent and can get crowded often, so expect some company.

Before that, the surf is a bit of a grind. From Friday morning, August 7th through to Friday morning, August 14th, it’s a lot of marginal surf with light cross-onshore winds. Mornings are generally the worst. The swell sits around 3ft to 4ft, and it’s cleanest in the afternoons when the wind goes cross-offshore, but the scores are low. Not worth getting too excited about.

Saturday morning, August 15th is a write-off with a choppy cross-onshore, but the afternoon of Sunday, August 16th cleans up nicely with a cross-offshore breeze and 4ft of SW swell. That’s a decent option.

The other real standout is Thursday afternoon, August 20th. The swell picks up to 4ft from the SSW, period 15 seconds, and the wind goes light cross-offshore. The combined energy is 603, which is moderate. The conditions are clean, and the guidance says you can expect very good surf. Keep an eye on that one.

Monday afternoon, August 17th also looks clean with 3ft of SSW swell and a light cross-offshore breeze. It’s a good, reliable runner-up.

The later days from August 19th onward have a similar pattern: small, clean afternoons, and mornings that are often blown out by a cross-onshore wind. Nothing huge, but plenty of windows for a wave.

The best session on offer without a doubt is Friday afternoon, August 14th. The combination of glassy wind, strong energy, and a solid 5ft groundswell at a reliable reef break makes it the one to circle on the calendar. The Thursday afternoon, August 20th, is the back-up plan for a cleaner, smaller wave.
