Navegantes Surf Forecast and Surf Report

Alright, mate, Rusty here. Let’s break down this run for Navegantes. It’s not going to be a classic stretch, but there are a few windows where you might get some fun if you pick your moments. The opening days are weak, but there’s a pulse of more energetic swell around the 9th, and a couple of clean, glassy mornings that could be worth a paddle.

The first proper surfable window is Friday morning, the 7th. It’s small – only around 3ft from the ENE with a short 8-second period. The wind is light and cross-offshore, so it’s clean, but the energy is weak (94). It’s rideable but nothing to write home about. That afternoon, the wind swings onshore and it chops up, so forget it.

Saturday the 8th is more interesting. The swell drops a bit – around 2ft – but the period jumps to 15 seconds, proper long-period groundswell from the SE. The energy jumps into the moderate range (242-289). The morning has a light cross wind, but the afternoon cleans right up with a cross-off breeze. This is about as good as it gets in the first part of the week. Small, but clean, and that long period will give the waves some push down the beach.

Sunday the 9th sees the biggest swell of the early run – around 4ft from the SSE, with a 13-second period. The energy is strong, at 600. But the wind is a cross/cross-on and it’s raining, so it’s going to be messy. Not worth the hassle unless you’re desperate.

Monday and Tuesday, the 10th and 11th, are poor. Swell drops back under 3ft, and the wind is cross or cross-shore. Tuesday afternoon sees heavy rain. It’s a bit of a dead zone.

Then we get a couple of gems. Wednesday morning, the 12th, has 2-3ft of SE swell with a 13-second period and glassy conditions. The energy is moderate (245). It’s clean and small, perfect for a longboard. That afternoon stays glassy too. Thursday the 13th morning is similar – around 2ft, 12 seconds, glassy, and clean. These are your best bets for a proper surf in the first week, but they’re not big. You’ll be hunting for corners.

Friday the 14th goes a bit ordinary – light rain and cross winds, but the swell holds around 2-3ft with a 14-second period. The energy is still moderate (334). It’s surfable but not clean.

The weekend of the 15th and 16th is poor. The swell drops to around 2ft and the period shortens. Sunday the 16th sees stronger winds – up to 18 mph – and the swell gets a bit jumbled. Not your friend.

Now, the 17th of August, which is Monday, brings a bigger pulse – 6-7ft of ENE swell, but with a short 7-second period and strong cross-onshore winds. The energy is strong (711), but with that onshore wind and short period, it’s going to be a washing machine. Too big for beginners and messy for everyone else. That afternoon drops to around 5ft, but it’s still poor.

Then, two days later, we get the standout of the whole period. On Wednesday the 19th, the wind drops to zero – absolutely glassy – and there’s a clean 3-4ft of easterly swell with a 9-second period. The energy is moderate (224). This is your day. Clean, glassy, and fun-sized. The morning is your window, because the afternoon turns onshore.

After that, things taper off again. The 20th and 21st have small, clean surf – around 2ft from the SE with 11-second periods – but the energy is weak. The mornings are glassy and surfable, but you’ll be scratching for waves. The 22nd is the final day in the window, and it’s small with a short period, so not much to get excited about.

Overall, there are two real standouts: the glassy mornings on the 12th and the 13th for small, clean long-period surf, and the standout of the whole run is the glassy Wednesday morning on the 19th. That’s your pick of the litter. A few other mornings are surfable, but you’ll be working for it.

The water temp is around 67°, about 2° warmer than average for this time of year – nothing unusual, just a touch on the mild side.

Crowds at Navegantes are sometimes an issue, so when the small, clean windows hit, you might have some company. The good ones will be worth sharing.

Alright, that’s the picture. Keep an eye on that 19th.

Rusty.
