The Lowdown
Alright folks, Rusty here. Let’s dive into what’s on offer for this stretch of the Costa Azul. We’re looking at a solid, drawn-out run of waves, but don’t go expecting anything huge or dramatic. It’s a subtle, quality-focused window for the experienced crew.
The Rock-Costa Azul is the main game in town, a consistent reef setup that knows how to handle a swell. The water temp is sitting pretty much spot on for this time of year, so no surprises there. The pattern starts off a bit slow and messy, but the second half of the first week and into the middle of the run is where the magic hides.
The real standout is Thursday, August 13th. The morning starts glassy with a light 3 ft swell from the SW, and it just gets better into the afternoon. By then, the wind is dead calm, glassy conditions, with the swell holding at 3 ft from the SW, but the energy is pumping at a solid 696 (moderate). The period is a lovely 15 seconds, which is a proper groundswell. For a reef, this is perfect: clean, lined-up, and all to yourself if you’re lucky. This is the best session of the run.
The other big moment to circle is Saturday, August 15th. The afternoon sees a clean, cross-off breeze with a 4.3 ft SSW swell. The energy is really humming at 851 (strong), and the period is a solid 16 seconds. This is punchier than Thursday, still very clean, and a great call for those who want a bit more push.
The following week is quieter. The swells drop, but the winds stay favorable. Tuesday, August 25th is a late highlight, with a very long period 22-second groundswell from the SW. The swell is only 2.6 ft, but with that kind of energy (965 - strong), it’s going to produce some beautifully shaped, walled-up waves at the reef. Perfect for a longboard or a log if you’ve got the patience for the long lulls.
Keep in mind, this spot is advanced and often has a crowd. The long period swells (like the 22-second one on the 25th) will make the waves stand up nicely on the reef, but the sets will be widely spaced. Paddling out will be easy, but you’ll be waiting for the good ones.
Overall, it’s a solid run with a few absolute gems. The first week has the best combo of size and clean conditions. Don’t sleep on the 13th or the 15th.

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.
