The Lowdown

Alright folks, Rusty here. Let’s look at what’s cookin’ for The Rock-Costa Azul over the next couple of weeks. This is a reef break that needs a good S swell to really fire, and when it lines up, it’s got that advanced-level punch. The water is a balmy 89°F right now, which is about 7°F warmer than normal for this time of year – that’s very unusual, so you can leave the booties at home.

The first real standout kicks off on Monday the 24th of August. The swell is about 5ft from the SSW with an 11-second period. The combined wave energy is 980 (moderate), and we’ve got a clean cross-off wind. It’s not gigantic, but it’s clean and that reef will shape things up nicely. Expect very good surf conditions. Crowds are often here, so if you’re after a peak, get on it early.

Tuesday the 25th is a tale of two halves. The morning is messy with a cross-on wind and a choppy 5ft. But Tuesday afternoon? That’s the sneaky good session. The swell drops to 2ft but the period stretches out to a very long 16 seconds, and the wind goes glassy. That’s a clean, lined-up groundswell. For a reef like this, that long period at that size is a dream – perfect shape, long waits between sets, easy paddle.

We then hit a bit of a lull. Wednesday and Thursday (26th, 27th) are small, with waves around 2ft to 3ft. Not much to write home about, though Thursday afternoon has a nice 18-second period with clean conditions – worth a look if you’ve got a log.

Friday the 28th sees a boost. The morning is 4ft with a 17-second period, but the wind is light cross-onshore. The afternoon picks up to 5ft from the SSW, same long period, and a cross-off wind. The energy jumps to 1462 (moderate), and it’s clean. This is for the experienced crew – 5ft on a reef with long period is a proper session.

Saturday the 29th and Sunday the 30th keep the 4ft to 5ft SSW swell going. Sunday afternoon is the pick here – offshore wind from the W at 9 mph, clean lines, 4ft. Very good conditions.

Into the new week, Monday the 31st is a mixed bag. Tuesday the 1st of September has a glassy morning with 3ft, and a clean afternoon with 4ft. Nice, fun size.

Now, a real standout pops up on Thursday the 3rd of September. The swell hits 5ft from the SSW with a massive 19-second period in the morning, and the combined energy is 1835 (moderate-to-strong). The afternoon is even better: 5ft, 17-second period, cross-off wind, and the forecast says excellent conditions for experienced surfers. This is the session to circle on the calendar. The energy is there, the shape will be epic.

Friday the 4th of September keeps that energy high with 5ft SSW and a score that says excellent again, though the wind is a bit more cross-off and messy in the morning. The afternoon remains clean and excellent.

We taper off slightly after that, with the 6th of September offering a clean 4ft, and a final late-season stand-out on Monday the 7th of September: 4ft, 15-second period, and a light offshore wind from the WSW, delivering clean, excellent conditions for experienced surfers again.

Overall, the first week has a few good windows, but the real grunt comes around the 3rd and 4th of September. If you can paddle this reef, that’s the time.

This is Rusty, signing off.

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.

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.
