Zippers-Costa Azul Surf Forecast and Surf Report

Alright, Rusty here, let’s get into it. We’ve got a look at Zippers-Costa Azul (Costa Azul) coming up. The water's sitting at 89°F, which is much warmer than normal for this time of year – that’s a solid 7°F anomaly, so it’s gonna feel like a bathtub out there.

The first few days are pretty average. Monday the 24th has a bit of a rough morning with cross-onshore wind and some choppy 4ft SSW swell, but the afternoon cleans up nicely. Tuesday the 25th is similar: mornings are marginal with a light cross-on, but the afternoons turn clean with a cross-off breeze. The swell drops off mid-week, with Wednesday the 26th and Thursday the 27th seeing small 2ft to 3ft waves – not much to write home about, but the afternoons are clean if you’re on a log.

Now, if you’re looking for the standout, lock in Friday the 28th afternoon. The combined swell energy is pumping at 1496 (moderate-strong), with a solid 5ft SSW groundswell at a long 17-second period. That’s gonna produce some proper lines. The wind is cross-off from the WSW, so it’ll be clean. This one’s for the intermediate crew – big enough to be fun but not too heavy.

Saturday the 29th keeps the energy up with a 5ft morning and 5ft afternoon, both clean in the afternoon. The energy stays high at 1413 and 1325. Sunday the 30th gets a bit messier with cross-shore wind in the afternoon, but the morning has a light cross-on.

Looking into the first week of September, Monday the 31st is a real gem for the early birds. The morning is glassy – dead calm wind – with a 4ft SSW swell. That’s the kind of session where you’ll be trading waves with no chop. Tuesday the 1st and Wednesday the 2nd are more marginal, though Wednesday afternoon pushes back up to 6ft at 1245 energy, but with a cross-on breeze.

The end of the run gets a bit lumpy. Thursday the 3rd through Saturday the 5th sees some bigger swell in the 5ft to 6ft range, but the wind is onshore or strong cross-onshore, making it choppy and messy. That’s more of a kite-surfing setup than a paddle session. The good news is things clean up again by Sunday the 7th and Monday the 8th. Monday the 8th in particular is worth a look – the morning is glassy with a 3ft long-period 19-second SW groundswell, and the energy is moderate. That’s a sneaky good end to the window.

Overall, the best bet is Friday 28th afternoon for size and cleanliness, with Monday 31st morning as the glassy, rippable runner-up. The rest of the window is a mix of clean windows and lumpy days, but there’s enough to keep you in the water.
