Zippers-Costa Azul Surf Forecast and Surf Report

Alright, Rusty here. Let's get into it for the Costa Azul area, specifically Zippers. The ocean’s got a bit of a pulse coming through, but it’s not gonna be firing every day, so we gotta pick our moments. The water’s sitting at 87°, which is much warmer than usual for this time of year, so you can leave the steamer at home.

We kick things off on Monday the 10th, but honestly, it’s a bit of a dud to start. The swell is tiny at 2 feet from the SSW with a long 19-second period, and the cross-shore wind is putting a slight chop on it. The combined swell energy is moderate (548), but it’s just not waving the white flag for a good paddle. You’d be scratching for scraps.

Tuesday morning the 11th sees a little bump to 3 feet, still a long period (18s) from the SSW, but the wind is onshore, making it messy. The afternoon cleans up a bit with a cross-offshore breeze, but the swell drops to 2 feet. Still not worth getting too excited about.

Now, Wednesday the 12th… that afternoon is a little moment of magic. We’ve got 3 feet of SSW swell at 16 seconds and the wind goes glassy, dead calm. That’s prime time for Zippers. The energy is moderate (469), but clean, glassy conditions on a consistent break like Zippers will turn that ankle-to-knee high into something you can actually have fun on. It’s for the intermediate crew, and the crowds are often there, so don't expect to have it to yourself.

Thursday the 13th afternoon is another clean window. Cross-offshore wind from the west, 3 feet at 15 seconds from the SW. The energy jumps to solid moderate (698), and the conditions look very good. This is a solid pick for the week.

Then we get to Friday the 14th afternoon. This is the standout of the whole run. The swell pumps up to 5 feet from the SW with a 17-second period, and the wind is light and cross-offshore. The combined energy hits a strong 1214. This is excellent surf for experienced surfers. Not for beginners—it’s over the 5-foot mark and will have some punch. But for the crew who know what they’re doing, this is the session to circle on the calendar.

Saturday the 15th morning still has 5 feet from the SW, but with an onshore wind, it’s not as clean. The afternoon drops a touch to 4 feet, but the cross-offshore wind cleans it up again, making it another very good option.

Sunday the 16th is a bit of a mixed bag. Morning is marginal with onshore wind, but the afternoon turns glassy with 4 feet of SW swell at 14 seconds. Very clean, fun waves.

After that, from Monday the 17th through to the end of the run on August 25th, the swell hangs around the 2 feet to 4 feet range, but the consistency and wind alignment get fiddly. There are some clean moments—like Monday the 24th morning with glassy conditions and 2 feet of SW swell—but the energy is weak to moderate, and the windows are short. The second week is mostly marginal, with a few tidy afternoons if you’re desperate for a paddle.

Final call: Friday the 14th afternoon is your absolute best bet—biggest swell, cleanest wind, and strong energy. Wednesday the 12th afternoon and Sunday the 16th afternoon are the runners-up, especially if you want a glassy, mellow session.

Rusty.
