The Lowdown
Righto, grab your wettie, let’s have a look at what’s on offer at The Rock-Costa Azul over the next couple of weeks.
First up, the water is a toasty 89°F, which is *much warmer* than normal for this time of year – you’ll be surfing in a bath. Don’t expect any hero waves just yet though. Sunday the 23rd is a write-off with a tiny 2ft SSW swell and a messy cross-shore wind. You’d be better off staying on the beach.
Monday the 24th isn’t much better. Morning is still a scratchy 4ft with that cross wind, but the afternoon cleans up nicely with a cross-offshore breeze and a 5ft SSW swell. It’s not going to be a classic, but it’s the first clean window we get. The swell energy is moderate (959).
Tuesday the 25th is where things start to look interesting. The morning is a bit of a write-off with a light onshore breeze, but Tuesday afternoon? That’s the first real standout. We’ve got a clean 2ft SW groundswell rolling in at a long 16 seconds, with a glassy cross-offshore wind. The energy is moderate (543) but the wave quality is solid. For a reef break, that long period will really line up, giving you long, drawn-out walls. This is the pick of the first week.
We hit a bit of a flat patch from Wednesday the 26th through Thursday the 27th – tiny swell and a mix of onshore and cross winds. Friday the 28th sees a bump in size to 4ft and then 5ft SSW, with that long period (17s) and moderate energy (1151-1467), but the wind is a bit messy. The real action picks up from Saturday the 29th, with 5ft SSW swell, decent energy (1550), and a clean cross-offshore breeze in the afternoons.
Now, if you’re an experienced surfer, mark your calendar for Monday the 31st of August. The morning is an absolute dream: 5ft of SSW groundswell, a 10-second period, and *glassy* conditions. The swell energy is moderate (811) but the clean, windless surface will make it feel like a million bucks. That’s your second standout.
After that, the first week of September gets a bit lumpy. Tuesday the 1st has a clean 5ft SSE swell in the afternoon, and Wednesday the 2nd offers 5ft to 6ft with light winds, but the swell direction is a little off for the optimum S direction.
Warning: From Thursday the 3rd of September, things get serious. A massive swell hits, with heights over 8ft and a combined energy reading of 2768 – that’s strong energy. By Friday the 4th, it’s cranking 12ft with a huge 5609 energy reading. This is *expert-only* territory and the wind is ugly. The swell is simply too big for this break, and it’s blown out. Kite surfers might love it, but for paddle surfing, it’s a no-go.
It calms down a bit on Saturday the 5th with 7ft SSW, but still not ideal. Sunday the 6th? Another massive pulse: 16ft of SSE swell with an incredible 8140 energy reading. Again, too big and the wind is onshore. This is a dangerous, heavy day.
The very last window, Monday the 7th of September morning, offers a last chance: 8ft SSW swell with a short 8-second period, but it’s *glassy* and clean. The energy is moderate (1034). That’s a solid, clean wave for experienced surfers only – it’s a good way to finish the run.
So, to sum it up: the best windows are Tuesday afternoon the 25th for a small, clean long-period swell, and Monday morning the 31st for that glassy perfection. The second week is mostly big, messy, and dangerous for all but the most hardcore.
Stay salty.

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.
