Rio Nexpa Surf Forecast and Surf Report

Right off the bat, the ocean’s got a pulse. It’s not a monster, but there’s consistent, solid southwest groundswell lining up all the way through the window, and Rio Nexpa is the spot that’s going to be feeling it. The water’s sitting at a warm 88°, which is a touch warmer than usual for this time of year, so you can ditch the booties and enjoy the tropical bath.

The action kicks off on Tuesday the 8th with some clean, glassy conditions. The swell is a modest 3ft with a solid 13-second period from the SSW, and the energy is moderate at 620. It’s not huge, but the calm morning wind will have it looking fun and rippable. The afternoon gets a little sloppy with the cross-on breeze, so make the most of the morning session.

Wednesday the 9th is where things start to firm up. That SSW swell pushes to 3ft but with a longer 16-second period, and the energy jumps to 697. The morning has a clean cross-off wind, and the forecast is calling for very good surf. It’s still smallish, but the push and shape will be there.

Thursday the 10th looks like the first real standout. The swell builds to a consistent 4ft, still from the SSW with that long 16-second period. The energy is strong at 880, and the morning cross-off breeze keeps it clean. This is the day to get your fill. The waves are going to have some proper push to them, and it won’t be too overwhelming.

Friday the 11th and Saturday the 12th settle back slightly, with 4ft and 3ft on the face. The periods drop a touch, but the mornings still have that glassy, clean feel that makes this river mouth a joy to surf. It’s a good spell of fun, workable waves.

Sunday the 13th and Monday the 14th see the swell dip a little more, down to 2ft-2ft. The period stretches way out to 18-19 seconds, which is a true groundswell. It’s a bit weaker on energy, but those long-period lines should still wrap nicely into the point.

Then, the ocean comes back to life. Tuesday the 15th sees the size bounce back to 4ft, and the energy is back up to a solid 834. The real highlight, though, is shaping up for Wednesday the 16th. The SSW swell jumps to a chunky 5ft, and the combined energy hits a strong 1102. There’s a risk of thunderstorms in the morning, but the wind is light and cross-off, promising excellent, meaty waves at Rio Nexpa.

The following stretch from Thursday the 17th through the 19th continues that solid run. Swells hold around 4ft with strong energy, and the morning conditions keep delivering clean, glassy or cross-off winds. This is a fantastic, sustained run of quality surf.

Heading into the deeper forecast, the 20th and 21st of September continue the trend. The swell stays at a consistent 4ft, the energy remains strong between 859 and 911, and the mornings have that magic glass. It’s looking really good, though as we get out over a week, it’s best to treat the details as promising but not set in stone.

The last few days of the window on the 22nd and 23rd hold onto that 4ft of swell, but the afternoons get blown out by stronger cross-onshore winds, especially on Wednesday the 23rd when it gets properly choppy. The mornings are still the go-to, but the midday and afternoon sessions will be a write-off.

All in all, this is a quality run for Rio Nexpa. It’s a very consistent period, and the pick of the bunch is Thursday the 10th and Wednesday the 16th – both mornings offer the best combination of size, energy, and clean conditions. It’s a river mouth, so that long-period swell can get a bit straight at times, but the sheer consistency and the warm water make this a great stretch to be in the water.
