The Lowdown
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.

Information about the The Rock-Costa Azul Surf forecast
The above surf forecast table for The Rock-Costa Azul provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Rock-Costa Azul can be found by selecting the local surf guide option on the grey menu. Our The Rock-Costa Azul surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for The Rock-Costa Azul may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
