The Lowdown

G’day, Rusty here. Let’s get into it for The Rock-Costa Azul (Costa Azul). This is a reef break, advanced only, and it’s consistent. The water is sitting at 87°F, which is much warmer than normal for this time of year, so you’ll be sweating in your wetsuit if you’re wearing one at all.

The next few days are a bit of a mixed bag, but the real standout is Friday afternoon, 7 August. We’ve got a clean 3ft swell from the SSW, period a long 17 seconds, and the wind is a light cross-off 6 mph from the WSW. The combined energy is moderate at 576, and it’s going to be clean. That’s a lovely little window for a late session.

Saturday morning, 8 August, is a bit disappointing – the wind is cross-on from the SSE, and the conditions are marginal. Saturday afternoon picks up again with a clean cross-off from the WSW, but the swell is still around 3ft, and the period drops to 15 seconds. Not terrible, but not the pick.

Sunday, 9 August, is similar – morning has a cross-shore wind and the swell is 3ft from the SSW at 14 seconds. Afternoon cleans up with a cross-off, but the energy is dropping to 345 (weak). Worth a look if you’re keen, but it’s not firing.

Monday morning, 10 August, is another good one. Clean cross-off wind, 3ft SSW swell, period 13 seconds, and the combined energy is 588 (moderate). The forecast says “very good,” and I’d agree. That’s a solid morning session.

Tuesday, 11 August, is interesting. Morning has a light cross-shore, 3ft at 18 seconds, energy 768 (moderate). The afternoon brings a risk of thunderstorms, but a moderate offshore from the WNW at 12 mph, with a 2ft SW swell at 18 seconds – that’s a long period and clean. For experienced surfers, that’s a fun, punchy option.

Wednesday, 12 August, is the best of the week. Glassy conditions in the morning, 3ft SW swell, period 16 seconds, energy 501 (moderate). The afternoon is clear, light offshore from the NW, same swell. That’s about as good as it gets for this break – clean, lined up, and no wind messing it up.

Thursday, 13 August, has a glassy afternoon again, 3ft SW swell at 15 seconds, energy 597 (moderate). The morning is light cross-shore, so wait for the afternoon glass-off.

Friday, 14 August, is the big one. The morning is a write-off with onshore wind, but the afternoon is excellent – 4ft SSW swell, period 17 seconds, combined energy 1008 (strong), and a light cross-off from the SW. That’s the best swell size and energy of the whole outlook, and clean. For experienced surfers, this is the session to lock in. Keep in mind that a long period like 17 seconds can make the waves break a bit straight at a reef, but it’s still a standout.

Saturday, 15 August, has onshore wind in the morning and a risk of thunderstorms in the afternoon with a light cross-on. The swell is still 4ft from the SSW, but the wind is messy. Sunday, 16 August, sees the swell drop to 4ft, with a clean cross-off in the afternoon – that’s a decent option if you’re around.

From Monday, 17 August, through to Saturday, 22 August, the swell stays in the 2ft to 3ft range, mostly from the SSW. The wind is a mix of cross-off and cross-on, with a few glassy windows. The best of the tail end is Wednesday afternoon, 19 August, with a clean cross-off, 3ft at 14 seconds, and Saturday afternoon, 22 August, with glassy conditions, 2ft at 13 seconds. Both are small but clean.

Overall, the standout is Friday afternoon, 14 August – that 4ft, 17-second swell with light cross-off wind is the best on offer. The water is much warmer than usual, so you’ll be comfortable. Expect crowds at this spot, especially on the good days, because it’s consistent and exposed. Stay safe out there.

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. 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.
