The Lowdown
Alright, Rusty here. Let's take a look at what we've got coming up at The Rock-Costa Azul.
The water temperature is sitting at 88°, which is a whopping 5° warmer than normal for this time of year. It's very unusual, and you'll feel like you're surfing in a bath.
We're starting off a bit rough, I won't lie. The whole first week is a mixed bag. Wednesday the 2nd kicks off with big, messy energy from a 10ft SSE swell at 12 seconds piling in—that's a combined energy reading of 3531, which is strong. It's too big for this break in the afternoon, even with favorable wind and tide. The morning is a total write-off with E wind on it.
Thursday the 3rd stays big and bumpy, a 10ft SSW swell but with a cross-onshore chop. Friday the 4th is smaller but still not right—an 8ft SW swell with cross-shore winds making it choppy. Saturday the 5th has a tiny 5ft SSW swell, but it's a 16-second period, which at a beach setup like this will roll in straight and fat.
Now, hold on to your board. The standout is Sunday the 6th morning. You get that 4ft SSW groundswell with a 15-second period, and the wind is dead glassy from the south at 3 mph. The combined energy is a moderate 1481, but it's clean. This is prime for experienced surfers—it's a reef break after all, so the long period will wrap in nicely. That's the best wave of the whole 16-day window, right there. The crowds are "often," so expect some company.
The rest of the first week? Nothing else really jumps out. Monday the 7th morning has a 6ft WSW swell with clean 6 mph cross-offshore winds, decent but not a stand-out.
We then hit a bit of a lull. From Tuesday the 8th morning through to Wednesday the 16th, the swell stays small—hovering between 2ft and 4ft. The winds are often light and clean, so it's not a total loss, but the energy is weak for most of it. Thursday the 10th has a glassy 4ft SW swell from a 16-second period, which is fun but not a hero session. Lucky for you, there's a tiny pulse of long period swell on the 17th afternoon—a glassy 2ft SSW swell at 21 seconds. Very long period, so very clean lines, but you won't be doing it on a big board.
Overall, the 6th is your day. The rest of the first week is a write-off except that one session, and the second week is small but often clean. If you need waves, get out on Sunday the 6th.
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.

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.
