The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here with a look at the surf ahead for The Rock-Costa Azul. This is a consistent, exposed reef break, so it handles a bit of everything, but we gotta be picky about the wind.

We're starting off a bit slow. The first half of this 16-day window is a waiting game. There's small, long-period SSW groundswell bumpin' in from the 17th of August, but the energy just isn't there for a proper session. The combined energy is a weak 728 (kinda meh). On top of that, the wind is a moderate cross-offshore from the WSW, which isn't terrible, but the conditions are marginal. You'll see a few afternoon windows with cleaner conditions and slight air, like on Tuesday the 18th, but the swell is too small to get excited about. Honestly, we're looking at a solid week of either clean but tiny surf or onshore chop.

Water temps here are cranked up nicely – we're talking 89° at the start, which is a whopping 7° warmer than normal for this time of year. It’s like a tropical bath, so you can ditch the thick rubber.

The real story begins at the end of August heading into September. The standout session is undeniably the afternoon of Friday, August 28th. That's the one. We've got a proper SSW pulse pushing the combined energy up to a strong 1668, with the swell jumping to a solid 5ft. The period stretches out to a very long 18 seconds – that's pure groundswell, bringing plenty of grunt. The wind goes light offshore from the WSW, so it'll be clean as a whistle. This is excellent, powerful reef surf for experienced surfers. The only bummer is that a spot like this can get crowded, so you’ll want to be early.

Leading into that, the Saturday the 29th holds a similar size at 6ft with a 16-second period, but the wind is a light cross-onshore, so it won't be as perfect as Friday. Still plenty of energy, but just not the same quality. By Sunday the 30th we’re still seeing a fun 4ft SSW swell with clean conditions in the afternoon, but the energy is dropping back to a moderate 847. Then we hit a bit of a lull before a final pulse on Tuesday, September 1st, with 6ft of SSW swell, but the wind is a stronger cross-off at 15mph, making it a bit more challenging. Still, that Friday the 28th is the clear winner – mark it on the calendar.

Rusty, signing off.
