The Lowdown
Alright folks, Rusty here. Let’s get into it.
Bit of a slow start, but there’s a window of fun coming. The Rock-Costa Azul is a reef setup, and it’s consistent, so it’s got potential. The water is feeling much warmer than normal for this time of year, about 86°, so you’ll be comfy in a spring suit.
We kick off on Friday the 31st of July with a small 4ft SSW swell, but it’s a bit of a write-off really – cross-off wind at 15 mph and the energy is moderate (467). Not worth the paddle.
Saturday the 1st of August is a bit of a mixed bag. Morning is tiny, 2ft SSW, but the afternoon cleans up nicely with a solid offshore W wind at 15 mph. The swell’s still small, but it’s clean with moderate energy (414). A fun little session if you’re desperate.
Sunday the 2nd and Monday the 3rd offer similar small waves, 2ft to 2ft, with the afternoon windows seeing some clean offshore conditions. Nothing to write home about though.
The real standout starts to build from Friday the 7th of August. The afternoon session sees a 3ft SSW groundswell with a period of 17 seconds – that’s some proper long-period energy. The wind is cross-off at 9 mph, and the wave energy is strong (585). This is a reef break, so that long-period swell will wrap in nicely. Get on it.
Saturday the 8th of August carries it on. Morning is a touch bumpy, but the afternoon is clean with a light cross-off breeze and a 3ft SSW swell, period 15 seconds. Energy is strong (511). This is another top session.
Looking further ahead, Wednesday the 12th of August has a glassy afternoon with a 3ft SW swell, 16 second period, and moderate energy (507). Then Thursday the 13th of August morning is glassy with a 3ft SW swell, 15 second period, and strong energy (570). That’s another winner.
The best on offer? Friday the 7th of August afternoon and Thursday the 13th of August morning. Both have clean, glassy-to-offshore conditions, decent long-period swell, and that reef setup will handle it perfectly. The Rock-Costa Azul gets crowded often, so get there early.
A few other days in the second week have surf, but the wind is a bit more onshore or bumpy, so they’re not as clean. The energy is moderate to strong, but the quality isn’t there.
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.
