The Lowdown

Alright, let’s break this down. The first proper surf is on Thursday the 27th, so don’t worry, it’s not a long wait.

The Rock (Costa Azul) is a reef, so it’s selective. Water temp is 31° right now – that’s about 3° warmer than average, which is crazy unusual. You’ll be sweating in your spring suit.

For the best session, Sunday the 30th of August morning takes the cake. You’ve got a 1.6m SSW groundswell running on a 12-second period, combined energy at 1263 – strong, solid power. The wind is glassy from the east at just 5 km/h. Dead flat, pristine conditions. The reef handles it well, but at this size it’s for experienced surfers only. Crowds are likely because it’s a consistent spot, so arrive early.

Friday the 28th morning is a good warm-up: 1.3m, 17-second SSW groundswell, light cross breeze, energy at 1137. Clean enough, but with a bit of texture.

Then things go quiet. From Tuesday the 1st of September through Wednesday the 2nd, the swell drops under 1m and the wind turns onshore or cross-shore with chop. Combined energy falls between 360 and 691 – weak. Not worth the paddle on a reef.

The next real gem is Friday the 4th of September. Morning session is glassy again: 1.4m of 16-second SSW groundswell with a light offshore from the northeast at 5 km/h. Energy at 1226. That’s a top-tier combo. The afternoon holds with a clean cross-off breeze on the same swell. Both sessions are solid. Expect plenty of company.

Saturday the 5th afternoon has offshore wind from the west at 20 km/h on 1.2m of 15-second SSW groundswell. Smaller, but the wind is good and the reef will line it up.

From the 6th into the second week, the swell sits around 1m to 1.1m with cross and onshore winds. Not much to chase until Tuesday the 8th afternoon: 0.9m of SSW swell with a light southwesterly cross-off breeze – clean but small. Wednesday the 9th afternoon is another one to note: offshore northwest wind at 15 km/h on 1.1m of 16-second SW groundswell. Energy at 774, clean and rippable.

Thursday the 10th afternoon brings glassy conditions again, with 1.2m of 16-second SW swell, energy at 809. Light air, clean as a whistle.

So, your two top sessions are Sunday the 30th of August morning and Friday the 4th of September morning (and afternoon). Both have glassy or clean conditions on a decent groundswell. Everything else is fair to average, but those two are the real standouts.

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.

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.
