The Lowdown
Alright folks, Rusty here with the outlook for The Rock-Costa Azul. We’ve got a solid 16-day window, but it’s not all smooth sailing. The action kicks off on Monday, 20th July, with a bit of a slow start, but there’s a real sweet spot coming up if you’re patient.
The overall pattern is a building then easing swell, with a few classic windows of clean, offshore winds. The standout period is without a doubt Wednesday, 22nd July, through to the end of the following week. The water is sitting at a very unusual 85.5°F, which is much warmer than normal for this spot – a real treat.
Let’s get into it. Monday, 20th July is a write-off with a 4.3ft SSW swell and a cross-off wind that’s just not making it work. The combined energy is weak (989). Not worth a paddle.
Tuesday, 21st July starts slow with a 3.9ft SSW swell and a light cross-on, but the afternoon is where it gets interesting. The swell bumps up to 5.6ft from the SSW, with a consistent cross-off breeze and a solid combined energy of 1251. It’s a clean start, but the real magic is yet to come.
Wednesday, 22nd July is the absolute pick of the first week. The morning is glassy, with a 6.2ft SW groundswell (12-second period) and a combined energy of 1188. That’s clean, powerful, and the offshore wind is perfect. The afternoon holds up too, with a 5.9ft swell and clean conditions. This is for experienced surfers – the size is right and the quality is top-notch.
Thursday, 23rd July is a bit of a drop-off, with a tiny 1.6ft swell in the morning and a very long 26-second period. That kind of period is better for a reef or point, and the energy is low (750). The afternoon picks up a little to 3.6ft, but it’s not the main event.
Friday, 24th July is a mixed bag. The morning is a no-go with a small, onshore 2.0ft swell. But the afternoon is a sneaky good one – a 3.6ft SSW swell with a 21-second period and a clean cross-off, packing a combined energy of 1359. It’s a solid, clean, long-period groundswell.
Saturday, 25th July sees the swell building again, with a 4.3ft SSW in the morning and a 5.6ft in the afternoon. The cross-off wind holds, and the energy is ramping up (1505 to 2308). The afternoon is clean, but it’s a bit of a crowd magnet – this spot is “often” busy.
Sunday, 26th July and Monday, 27th July are a consistent run. You’ve got 4.6ft to 5.2ft SSW swells, clean cross-off winds, and combined energy between 1566 and 2037. These are excellent, reliable days for experienced surfers.
Tuesday, 28th July is a bit of a curveball. The morning is messy with a cross-on 6.2ft S swell, but the afternoon cleans up nicely with a cross-off and the same size. The energy is huge (2459 to 2611), but the quality is just marginal.
Wednesday, 29th July is a hard pass. The swell jumps to 9.8ft to 11.5ft, but it’s onshore and messy with a fresh breeze. The combined energy is massive (above 4000), but it’s for kites, not paddles. This is expert-only territory if you’re even thinking about it.
Thursday, 30th July is the same story – 9.8ft to 11.5ft swells, but the wind is cross or cross-on. The energy is still huge (3891 to 4045), but the break is blown out and too big. Keep the board on the beach.
Friday, 31st July is a return to form. The morning has a 6.6ft SW swell with a light cross-on, but the afternoon is the real winner. A 5.6ft WSW swell, combined with a light cross-off and a combined energy of 1540. It’s clean and punchy.
Saturday, 1st August and Sunday, 2nd August are another poor spell. The swell is 8.2ft to 11.5ft, but the wind is onshore or cross, and the energy is huge (2487 to 4605). It’s choppy, too big, and just not enjoyable.
Monday, 3rd August is a washout with an 8.2ft SSW swell and cross-on wind. The energy is high (2253), but the quality is poor.
Finally, Tuesday, 4th August is a fantastic end to the run. The morning is clean with an 8.2ft SW swell, a cross-off breeze, and a combined energy of 1978. The afternoon is even better, with an 8.2ft SW swell and a gentle offshore wind. The combined energy jumps to 2168, and it’s clean. This is another standout for the experienced crew.
For the best of the best, I’d nail Wednesday, 22nd July (morning glass) and Tuesday, 4th August (afternoon offshore). Both are clean, powerful, and have the right direction (

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.
