The Lowdown
G'day, Rusty here.
We've got a proper run of surf coming up at The Rock-Costa Azul, a reef setup that needs a south swell to really fire. The water is currently sitting at 88°F with a 5°F anomaly, which is much warmer than what you'd expect for this time of year, so you can leave the steamer at home.
The week kicks off with a sizeable, but messy, pulse on Thursday the 3rd. Swell is 8ft from the SSW with an 11-second period, but a cross-on southerly breeze at 9 mph is going to chop it up. The combined energy is a solid 2763, but it's not one for a paddle-out. Friday the 4th is more of the same in the morning – 7ft from the SW but still cross-on and choppy. The afternoon drops to 5ft, but the wind swings cross-shore, and with a 16-second period, the lines will be there, just not clean.
The standout window starts Saturday the 5th. Saturday morning sees the swell holding at 5ft from the SSW with a 16-second period, but the wind turns cross-offshore from the SW at 9 mph. The energy is still strong at 2085, and it's described as clean. By Saturday afternoon, the wind goes fully offshore from the W at 12 mph, with the swell at 6ft from the SW and a 13-second period. This is the pick of the first week – clean, punchy, and for experienced surfers only. Sunday the 6th keeps it clean with lighter cross-off and offshore winds, swell dropping to 4ft and 4ft, but still excellent.
Monday the 7th afternoon goes glassy with a 4ft WSW swell, though the period drops to 11 seconds, making it weaker at 851. The following week sees a steady drop in size, with a lot of glassy, clean conditions from Tuesday the 8th right through to the 17th. Most of these days offer knee-to-waist high, clean surf, so the longboard or a funboard will be the go.
The second real standout comes on the 17th and 18th of September. Thursday the 17th morning is glassy with a 2ft SW swell, but the period is a very long 21 seconds, pushing the combined energy up to 731. This is a proper groundswell, and given it's a reef, it will line up beautifully. Thursday afternoon holds with a clean 3ft from the SW at 21 seconds (884 energy). Friday the 18th is all glassy, with 3ft SW swell at 20 seconds and 19 seconds. This is a long-range forecast, so it's a promising one, but keep an eye on it – if it holds, it’ll be a dream session.
Crowds are listed as "often" here, so expect company, especially on those standout days. The consistency is good, so you won't be waiting long for a set.

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.
