The Lowdown

Alright, let’s talk about Molhes de Mampituba (river/jetties). The next couple of weeks have some good windows, but plenty of days where you’re better off doing something else. Water temp is about 65°F, right where it should be for this time of year.

The real standout is Monday morning the 27th. Glassy, no wind, and a clean 2 ft swell from the south with a 12-second period – that’s proper groundswell. The combined energy is 225, which is a solid moderate pulse. It’s small, but for a river jetty, that long period will make it fun. Get in early before the wind screws it up.

After that, it’s quiet until Friday morning the 31st. That morning we get 6 ft from the east-northeast, but the period is only 6 seconds, so it’s short and punchy. The energy is 430, a solid push. The wind is cross-off from the north-northeast at 15 mph, keeping it fairly clean. That’s more for the intermediate crowd – beginners might find it tough.

Then Saturday morning the 1st of August is the biggest: 7 ft from the east-northeast, 8-second period, and a strong energy reading of 866. That’s a lot of water moving. The wind is cross-off again at 20 mph, so it’ll be clean. But 7 ft at a jetty with short period is for experts only. The afternoon gets messy.

There’s a glassy little session Sunday afternoon the 2nd – only 3 ft, but the wind drops to nothing and the swell is from the east-northeast at 8 seconds. Small, clean, easy.

Tuesday morning the 4th is another one: 3 ft from the south-southeast, 11-second period, energy at 340, and light cross-off winds. That long period and good direction will make the jetties work nicely.

Wednesday the 5th morning: 5 ft from the southeast, 7 seconds, energy 321, clean. A good morning wave, but the afternoon gets chopped. Thursday the 6th morning: 4 ft from the south-southeast, 9 seconds, clean. Energy is 313. Friday the 7th morning is glassy – 4 ft from the east-southeast, 8 seconds, energy 251. Small, clean, fun.

From the 8th through the 11th, the wind turns nasty – strong onshore and cross-shore, making a mess of things. The best of that stretch is Tuesday morning the 11th: 2 ft from the south at 11 seconds, glassy, energy 151. Small but clean, and that long period will give it some life.

Your best mornings are the 27th, the 31st, and the 1st of August for size, but only if you’re ready for it. For cleaner, smaller waves, hit the 4th, 5th, or 7th. Crowds are common here, so expect some company on the good days.
