The Rock-Costa Azul Surf Forecast and Surf Report

G'day, I'm Rusty. Let's have a look at what's on the table for The Rock-Costa Azul (Costa Azul). This is a reef setup that's for advanced crew only, and it's a consistent spot.

Alright, first thing's first: the water is sitting at a toasty 89°F right now, which is a whopping 6°F warmer than usual for this time of year. That's a very unusual spike, so you'll be in boardies or a spring suit at most.

The first real action kicks off on Wednesday, the 26th of August, with a clean 3 ft swell from the southwest, with a period of 11 seconds. The wind is a light 6 mph cross-off, making for some clean waves. The energy is moderate at 410. It's a solid starter, but not the standout.

The real standout is Thursday, the 27th of August. The morning has a 3 ft SW swell, but the period jumps to 14 seconds, giving it more punch. The wind is a light 3 mph cross-on, so it's a bit touchy. But the afternoon is where it's at: the wind goes cross-off at 3 mph, the swell holds at 2 ft from the SSW, and the period extends to a very long 18 seconds. That's groundswell, and it'll be clean and lined up. Energy is moderate at 564. This is the pick of the early window.

Friday the 28th sees a jump in size. The morning has 4 ft SSW swell at 17 seconds, but the wind is a light cross-on, so it's a bit messy. The afternoon cleans up with a 12 mph cross-off, and 5 ft SSW swell at 17 seconds—energy is strong at 1422. It's good, but that wind is a bit of a puff.

The weekend brings more size. Saturday the 29th has similar 5 ft SSW swell, but the wind is variable. The morning is cross-on, and the afternoon is cross-off. It's a decent run, but Sunday the 30th gets a bit bigger. The morning has 7 ft SSW swell at 14 seconds with a cross-shore wind, so it's a bit choppy. The afternoon cleans up with cross-off wind and 6 ft SSW swell. At 7 ft, it's getting into the zone where beginners might struggle.

Monday the 31st sees a drop in swell. The morning has 5 ft SSW swell at 9 seconds, short period, with a cross-shore wind. The afternoon is a bit different: 3 ft SSW swell with a 16 mph offshore wind from the west. That's clean, but small.

Then we hit a bit of a dry spell. From Tuesday the 1st of September through to Thursday the 3rd, the surf is marginal. The swell stays around 3 ft to 4 ft, but the wind is mostly onshore or cross-on, and the scores are low. Not worth paddling out.

Friday the 4th of September brings a new pulse. The morning has 7 ft S swell at 11 seconds with onshore wind, so it's blown out. The afternoon is 8 ft S swell at 11 seconds with a cross-shore wind and a bit of chop. That's solid size, but the conditions are average. Energy is strong at 2206.

Saturday the 5th has 8 ft to 7 ft SSW swell, but the period drops to 10 seconds. The morning is cross-on, and the afternoon cleans up with cross-off wind. It's big, but the period is short, so it'll be a bit walled up.

Now, the real gem in the long-range is Sunday the 6th of September. The morning has 4 ft SSW swell at 15 seconds with glassy conditions. The wind is a ghostly 3 mph from the SSW. The afternoon is the same: 3 ft SSW swell at 15 seconds and glassy. Energy is moderate at 821 and 734. That's a proper session—clean, lined up, and easy paddling. This is a standout for the whole window.

Monday the 7th drops off to 3 ft SSW swell at 14 seconds with a light cross-shore wind. It's okay, but nothing special.

The last few days from Tuesday the 8th to Thursday the 10th of September are a mix. The 9th of September afternoon has a nice clean 4 ft SSW swell at 17 seconds with a cross-off wind, and the energy is strong at 1372. That's worth a look. The 10th of September afternoon also has a clean 4 ft SSW swell at 16 seconds with a light cross-off wind. Both are solid options to finish the run.

So, to wrap it up: the best bet is the 27th of August afternoon for the clean, long-period groundswell. The 6th of September is another cracker with glassy conditions. The 9th of September afternoon is also a good one. Get on it.

Rusty, signing off.
