The Lowdown

Alright, Rusty here, let's talk about what's on offer for the next couple of weeks.

We're looking at a solid run of surf coming up, starting this Thursday, August 6th. The Rock at Costa Azul is a reef break that's exposed to the swell, and it's a consistent performer. The water is a seriously warm 86°, which is much warmer than normal for this time of year, so you'll be in boardies or a springsuit for sure.

The first real standout hits on Thursday afternoon. The Rock is glassy with a light 3 mph wind out of the SW, and the swell is a clean 2 ft from the SSW. It's a long-period groundswell of 18 seconds, so there's plenty of energy in the water (combined energy of 482). The conditions are spot on for a quality session.

Friday morning starts a bit lumpy with a cross-on breeze, but it cleans up nicely by Friday afternoon as the wind goes cross-offshore. The swell is holding around 3 ft from the SSW. Saturday morning is another absolute ripper, with glassy conditions and the swell bumping up to 4 ft from the SSW (combined energy of 670). The period is down to 16 seconds, but it's still a solid groundswell.

We get a bit of a drop-off in quality on Sunday with a risk of thunderstorms and a cross-shore wind, but the swell is still around 3 ft. The second week sees a bit of a lull in the quality, with a lot of marginal surf days and cross-onshore winds. The winds are mostly light, though, so it’s not blown out.

Now, hold on to your boards, because the real standout of the whole 16-day window is shaping up for Friday, August 14th. The Rock looks absolutely pumping. The morning session has a clean 3 ft swell from the SSW with a lovely 18-second period, combined energy is a massive 1022, and the wind is a light cross-offshore. Then the afternoon gets even better. The swell jumps to 5 ft from the SW, with a 17-second period and a whopping combined energy of 1239. The wind shifts to a light offshore breeze from the NW. This is expert territory at that size, but it's going to be an incredible day for those who can handle it. The Saturday morning after that (August 15th) is still solid with a 5 ft swell, but the wind is a cross-shore, so not as clean.

For the rest of the second week, we're looking at smaller, cleaner conditions. The average swell is around 3 ft from the SSW, with lots of clean cross-offshore winds in the afternoons. It's a good run of consistent, rideable waves, even if it's not the size of that mid-August peak. Monday and Tuesday afternoons on the 17th and 18th look like the pick of the second week for a mellow, clean session.

The Rock is a reef break, and it can get crowded, so for the best sessions, particularly the Thursday afternoon (August 6th) and the Friday (August 14th), you'll want to be early. That Friday the 14th is the one to circle on the calendar.

Rusty.

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. If you surf the same spot (The Rock-Costa Azul) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
