The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next 16 days at The Rock-Costa Azul. This is a solid reef set-up that loves a good S swell, and it’s got a rep for being consistent. There’s a bit of a wait for the best of it, but the window opens proper this Sunday.
The water is a standout straight away – we’re looking at 88°F which is a massive 5°F warmer than normal for this time of year. That’s properly unusual, so you’ll be surfing in a bath. The overall energy through the period is solid, with combined energy readings well into the three-digit range, hitting over 1000 on Sunday, which is moderate to strong, so there’s plenty of push in the water.
Sunday, September 6th is the real deal. The Rock-Costa Azul is your best bet. You’ve got a clean 4ft SSW swell with a 15-second period – that’s proper groundswell, long and powerful. It’s an exposed reef, so that long period will wrap in nicely, giving you good shape and long lulls between sets to paddle out. The wind is glassy in the morning, switching to a light offshore from the WNW in the afternoon. This is a spot for advanced surfers only, and with the water temp and these conditions, it’s going to be a treat. The combined energy is strong at 1054.
Monday, September 7th sees the swell dropping a touch to 4ft, still from the SSW, still with a long 14-second period. The morning has a light cross-on breeze, so it won’t be as clean, but the afternoon cleans up nicely with a cross-off wind. It’s a solid option, but not the standout.
The rest of the first week sees the swell ease a bit, but there’s still fun waves. Tuesday, September 8th is smaller, 3ft in the morning, dropping to 2ft, but that afternoon has a 16-second period swell from the SW. The wind is a moderate cross-off, so it’ll be clean but a bit punchy. Crowds are often here, so expect company.
Wednesday, September 9th through to Friday, September 11th offers a consistent run of 3ft to 4ft SW swell, with periods holding strong at 14-17 seconds. The winds are mostly light offshore or glassy. Friday morning is absolutely glassy with no wind at all – that’s a rare treat for a reef, so paddle out early for silky conditions.
The second week, from Saturday, September 12th onwards, the swell drops off a bit, settling into the 2ft to 3ft range. The periods are still long, often 16-19 seconds, so there’s still quality in the water, just less size. The winds are generally light and favourable, with plenty of glassy mornings and offshore afternoons. Monday, September 14th has a 2ft, 18-second swell with glassy conditions – small but perfectly formed for a longboard. Tuesday, September 15th picks up a touch in the afternoon to 3ft, and Wednesday, September 16th sees a bit more size with a 4ft SSW swell. The best of the longer range looks like Saturday, September 19th, where you’ve got a 3ft SW swell with a 18-second period and glassy winds all day. That’s promising, but it’s a way off, so keep an eye on it.
Overall, the best on offer is crystal clear: Sunday morning, September 6th is the standout. Get out there early for the glass and that 4ft, 15-second groundswell. The second standout is Friday, September 11th for the morning glass. After that, the quality holds but the size drops, so pick your moments.
Rusty out.

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.
