The Lowdown
Alright, let’s have a look. This is The Rock-Costa Azul, just a single reef break that’s exposed to the south. It’s a consistent spot, but it’s for advanced surfers only. The water is cooking at 88°F, which is a solid 5°F above normal – that’s unusual warmth, makes a big difference when you’re sitting in the lineup.
We kick off on Wednesday the 2nd of September with a big south pulse. We’re talking 10 ft swell, 12-second period, with a 20 mph ESE wind blowing onshore. The energy is pumping at 3149. This is a powerful, serious swell. It’s not clean, but if you’re an expert looking for size, it’s there.
Thursday the 3rd and Friday the 4th drop to around 8 ft, but the wind stays onshore and cross-on, chopping it up. Not your best bet.
Then we get to the real gem. Saturday the 5th of September. The morning is still a little messy, but the afternoon is a beauty. The wind swings offshore from the WNW at 15 mph, and we’ve got a 4 ft SSW swell with a super long 16-second period. The energy sits at 1331. This is pure reef perfection: long-period groundswell, offshore breeze, clean faces. It’s not huge, but it is perfectly shaped. This is the best session in the window.
Sunday the 6th gives you a repeat – offshore wind in the afternoon, 5 ft swell, 12-second period. Clean and fun.
From Monday the 7th onwards, the swell starts to fade. You’re looking at 4 ft down to 2 ft for most of the second week. The wind turns frequently glassy or light offshore, which is a major win for wave quality. The periods stay very long, from 14 up to 21 seconds. The energy is weak to moderate (300s to 400s). This is small but clean reef surfing. Between the 11th and the 17th of September, there are many afternoons that are dead glassy – no wind, just smooth lines. It’s small, but if you want to get wet without a fight, it’s there.
One word of caution: on Wednesday the 9th of September, the offshore wind is cranking at 45 mph. It’s glassy, but it’s also a battle to paddle into a 3 ft wave. More of a workout than a wave.
The standout is clear as day – Saturday the 5th of September, afternoon session. Everything lines up.

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.
