The Lowdown

G’day, Rusty here. Let’s break down The Rock-Costa Azul. This is a consistent reef that’s exposed and loves a good swell. The water is a balmy 88°F, which is much warmer than normal for this time of year – over 4°F above the average, so it’s like a warm bath.

The first surf to look at is Saturday morning, August 29. We’ve got a 5ft SSW swell with a long 16-second period – that’s proper groundswell with solid energy (1303). The wind is a light cross-on from the south at 6 mph, so it’s a bit bumpy but not bad. The afternoon cleans up with a cross-off from the WSW at 12 mph, making for clean conditions. Still, the surf is marginal with tide issues, so it’s a picky session.

Sunday the 30th pushes bigger. The morning has 6ft from the SSW, period 14 seconds, energy 1370. That’s a solid size – a bit too much for beginners, but good for the experienced crew. The wind is a light cross-on from the SE at 6 mph. The afternoon drops to 4ft with a cleaner cross-off from the WSW.

Monday the 31st, the swell fades. Morning has 3ft, cross-shore from the south at 6 mph, light bumps. By the afternoon it’s 3ft with a stronger cross-off from the west, but the quality is poor.

We hit a lull through Tuesday the 1st and Wednesday the 2nd. The morning of the 1st has a risk of thunderstorms with a cross-on, but the afternoon goes glassy – zero wind, 3ft from the SSW. That’s a rare calm moment, but the swell is small. The best of that small window is the Tuesday afternoon glass-off.

From Thursday the 3rd through Friday the 4th, the swell picks back to 4-5ft, but the wind is onshore or cross-onshore from the SE and SSE at 12 mph, making for choppy, scrappy conditions. The energy is moderate to strong (1338-1846) but the quality is poor.

Now, the standout. Saturday the 5th of September is the pick. The morning has 4ft from the SSW, period 16 seconds, clean with a light cross-off from the WSW at 6 mph. The guidance says excellent conditions for experienced surfers. The afternoon keeps it going with a 4ft SSW swell and a moderate offshore from the west at 12 mph – clean and lined up. This is the one.

Sunday the 6th is also very good. The morning goes glassy with a 4ft SSW swell, 15-second period, and a slight air from the west. The afternoon stays glassy with a shift to NNW, still 4ft from the SSW. Two sessions of clean, long-period groundswell. Crowds are often, so expect company.

Monday the 7th sees the swell drop to 3ft, but the morning is glassy again with a risk of thunderstorms. The afternoon goes clean with a light offshore from the WNW at 6 mph. Small but fun.

After that, the swell fades into the second week. Tuesday the 8th has tiny 2ft waves but with a very long 18-second period in the morning, clean with a cross-off. The afternoon goes offshore from the NW, clean, but the size is small. Wednesday the 9th shows a slight bump to 3ft in the afternoon from the SW, period 17 seconds, clean with a light cross-off. Thursday the 10th has 3-4ft from the SW, but the wind is a mix of cross-on and cross-off, marginal.

From Friday the 11th through to Sunday the 13th, it’s all small – 2ft to 3ft – with periods dropping to 13-14 seconds. The wind is mostly cross-on or cross-off, but the energy is weak (282-444). There’s a clean afternoon on the 11th and 13th, but the surf is tiny.

Best on offer: Saturday the 5th of September. The morning session with 4ft SSW groundswell, 16 seconds, and a light cross-off wind is the cleanest, most powerful window. The swell is from the SSW, close to the optimum S direction for this reef, so it’ll wrap in nicely. Crowds are often, but for that quality, you’ll want to be early.

Rusty.

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.
