Molhes de Mampituba Surf Forecast and Surf Report

Alright, Rusty here, checkin' in from the coast. We've only got one spot on the radar for this stretch, and that's Molhes de Mampituba, a river/jetty setup. Let's get into it.

The window kicks off Saturday the 11th with some proper promise. We're looking at a solid run of fun-sized swell and those critical clean conditions. The water is sittin' at 59°, which is a good five degrees colder than usual for this time of year – so if you're paddling out this weekend, that thicker wetsuit is non-negotiable. The wave energy is moderate to strong (559).

Saturday morning, the 11th, is where you want to be. We've got a clean 4ft of groundswell rolling in from the ESE with a nice 13-second period, and the wind? Pure glass – 3 mph from the north. It'll be smooth as butter. The water is glassy, the energy is there, and it's lining up for some proper fun. It's a fairly consistent spot, and with that wind, you'll be smiling. The afternoon stays clean, with glassy conditions and a drop to 3ft, still plenty rideable.

Sunday the 12th? Sit it out. The wind swings to the SW, picking up and turning cross, putting a chop on the surface. Both the morning and afternoon are messy.

Monday the 13th morning gives us another look. A light WSW breeze, cross-off, keeps it clean with 4ft of swell, but the period drops to 8 seconds, so it's more of a wind swell, less grunt behind it. Still worth a paddle for a couple of hours before the onshore kicks in.

Now, look ahead to Tuesday the 14th morning. This is another highlight. Clean, cross-off wind from the north, and the swell jumps up to 6ft with a 10-second period from the SE. The wave energy is strong (590). It's got size and shape, and with clean conditions, those jetty waves will be running nicely.

The pattern continues through Wednesday and Thursday mornings with clean, cross-off breezes and waist-to-chest high waves. Solid fun.

Friday the 18th morning is when the swell really starts to juice up. You’ve got a clean 6ft from the ENE with a 9-second period, and the energy pumps up to 835, which is strong. This is the standout of the first week – bigger, punchier, and clean. It’ll be a busy bank, and it’s a fairly consistent spot that can get crowded often, so get there early.

The following week holds some serious size. Monday the 20th and Tuesday the 21st both show clean mornings with chest-to-head high waves, around 6ft to 6ft from the ENE. The energy stays strong. For a confident intermediate, this is gold.

Then things get wild. By Thursday the 23rd and Friday the 24th, the swell pushes well overhead, hitting 7ft to 8ft. The period drops to just 8 seconds, so it’s a lot of powerful, dumpy close-out energy. The wave energy is very strong (up to 1650). This is expert-only territory – these jetty waves will be heavy and unruly. The wind is onshore or cross, making it a messy, dangerous lineup. Honestly, if you're not a pro, stay on the sand. That kind of setup looks more interesting for kite surfing than paddle surfing.

The final few days of the outlook fade into a poor, choppy mix. So the call is clear: your best bets are the glassy Saturday the 11th morning, and then the clean, building swells from Tuesday the 14th morning through the 21st. The Friday the 18th morning is the big standout of the whole period – clean, strong, and thumping. Get on it.

Rusty.
