The Rock-Costa Azul Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it.

The next couple of weeks have a lot of swell coming through for The Rock-Costa Azul, but it’s not all going to be surfable. The real standout is definitely the first Sunday and Monday; we’ll get to that.

Right off the bat, the first recommendation is for Tuesday the 1st of September. It’s a small start with a 2ft swell from the SSW, but the period is a very long 18 seconds – that’s proper groundswell. The water is sitting at 88°, which is much warmer than normal for this time of year. On the down side, the wind is a light cross-shore, so it’s not glassy, but it’s rideable. The combined energy is moderate at 539. Not a standout, but a sign of things to come.

Wednesday the 2nd and Thursday the 3rd are a write-off. We’ve got onshore winds, risk of thunderstorms, and the swell jumps up to 8ft to 12ft with poor conditions. Thursday afternoon sees a 10ft SSW swell, but the wind is cross and it’s just too big for this reef break – it’s an advanced spot, but that’s pushing it into messy territory.

Friday the 4th is still a bit messy with a 10ft SW swell and cross-on winds in the morning, but the afternoon turns clean. The swell drops to 8ft, and the wind goes cross-offshore. The combined energy is still strong at 2257, but the wave comment says it’s marginal. Saturday the 5th has a 5ft SSW swell with a 16-second period and light cross-shore wind – clean but small.

Now, the best on offer. Sunday the 6th of September is looking excellent. We’ve got a 6ft WSW swell in the morning with a 12-second period, and the wind is a light cross-offshore from the SW. The combined energy is 1710, and the wave comment says excellent for experienced surfers. The afternoon picks up a little to 7ft, still with clean conditions and a light cross-offshore wind. This is the one to go for if you’re advanced. Expect it to be fairly clean, but remember, the period is 12 seconds, so it’s a solid groundswell with good shape.

Monday the 7th is also very good. The swell drops to 5ft from the W in the morning, but the wind is cross-on, so it’s a bit bumpy. The afternoon is the real gem: 4ft W swell with a light cross-offshore wind and clean conditions. The combined energy is 750 – moderate. It’s a good, fun day for the advanced crew.

After that, the surf drops off significantly. From Tuesday the 8th onward, we’re looking at swell heights between 2ft and 4ft, with periods mostly 13 to 19 seconds. The wind is generally cross-offshore or offshore, keeping conditions clean. The combined energy drops to the 200-900 range, so it’s on the weaker side. There’s a nice little window on Thursday the 10th: a 4ft SW swell with a 16-second period and offshore wind from the W in the afternoon. That’s clean and glassy-looking, but it’s small. The rest of the second week is small but clean, with the best being the 16th of September, where we see glassy conditions with a 2ft SW swell and a 14-second period. It’s not going to get you barrelled, but it’s a nice longboard session. This is a long-range call, so don’t lock it in just yet.

Overall, the first weekend is your best bet. Don’t sleep on Sunday the 6th.

Rusty.
