The Lowdown

Alright, Rusty here. Let’s have a yarn about what’s coming down the line at The Rock-Costa Azul.

The next fortnight is a mixed bag. The first week is pretty average, we’re waiting for proper clean waves. The real standout window looks to be next Thursday afternoon the 23rd of July through to Friday afternoon the 24th. But let’s take it day by day, yeah?

Starting off this Saturday the 18th, it’s messy. Onshore winds and weak energy kicking up poor conditions – not worth paddling out. Sunday’s no better, cross-on winds and poor surf. Monday the 20th is only marginal, with cross-shore winds and moderate energy, but you can probably sit it out. Tuesday the 21st stays marginal with a bit of swell around 4 ft from the SW, but nothing to get excited about.

Wednesday the 22nd shows some size coming up – about 6 ft to 7 ft from the SSW – but still only marginal because the wind’s messing it up. The energy ramps up strong with readings of 1518 and 1437. You’d need to wait for cleaner conditions.

Now, here’s the best run. Thursday the 23rd afternoon is the pick: The Rock-Costa Azul is glassy and smooth, with 6 ft SW swell (13-second period) and excellent conditions for experienced surfers. That’s the one you want. Friday the 24th afternoon is also a cracker: 4 ft of SW groundswell with a very long 21-second period, clean cross-off winds, and energy up at 1787. That’s a long-period swell that will line up beautifully for this reef break, with clean faces and long lulls between sets. This is a true standout – the combination of wind, swell direction matching the optimum S direction, and quality is spot on. Crowds are often here, so expect some company for these sessions.

Early the next week, from the 25th to the 28th, we’ve got inconsistent energy, onshore or cross-off winds, and only marginal quality. Nothing to race out for.

Then the forecast turns poor. From the 29th of July onward, fresh onshore winds and more poor conditions move in. By the 30th, it’s choppy and weak. The end of the run on the 1st of August offers a tiny glassy window in the afternoon with only 2 ft of SW swell – maybe a log session if you’re desperate. On the 2nd of August, a big 12 ft SSE swell rolls in, but the file says it’s too big for this break, so steer clear unless you're a proper expert and know the place.

Water temp is about average for this time of year, no major anomaly to speak of.

So, to wrap it up: hold out for Thursday the 23rd afternoon or Friday the 24th afternoon at The Rock-Costa Azul. Those two sessions are your gold. The rest is either marginal or blown out.

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.
