Molhes de Mampituba Surf Forecast and Surf Report

Alright, let’s get into it. The long-range models are pointing at one clear window of proper surf, and it’s all about that Sunday the 17th through Tuesday the 25th. Before that, it’s pretty messy with poor wind and lumpy conditions, so don't get too excited about the first few days.

We start things off on Saturday the 15th with a bit of a dud. There’s swell at Molhes de Mampituba, around 6ft to 7ft, but it’s short-period windswell at 7 seconds and a cross-shore NE breeze is chopping it all up. The energy is weak, just 562 and 640. Not worth the paddle. Sunday the 16th looks a little better in the morning with a bit more size, 8ft, and a NNE cross-off wind, but the energy is still moderate at 1109. The afternoon goes downhill fast. Honestly, the whole weekend is a wash.

Now, here’s where it gets interesting. Monday the 17th is the first real standout. The swell pushes up to 8ft from the ENE with a period of 9 seconds. Morning winds are light cross-off from the NNE, and the energy jumps to 1403, which is a solid step up. It’ll be clean and powerful, a proper river-mouth wave. That morning session is the pick of the first week. The afternoon cleans right up to glassy with a smaller 5ft wave, but the energy drops too.

Tuesday the 18th is a real letdown. The swell fades and swings around to the ENE, but the wind goes onshore and everything just gets messy. The energy is back down to 203 and 187, and the wave quality is poor. The mid-week from the 19th and 20th is pretty flat and weak. There’s only knee-to-waist high dribble with energy in the low hundreds. It’s a real lull, you’d be better off waxing your board and waiting.

The next glimmer comes on Friday the 21st with a small, clean morning wave from the SW, but it doesn't have much behind it. A bigger pulse of south swell shows up on Sunday the 23rd, with a long-period 14-second swell and strong energy of 1504. It’s a big push to 6ft, but there’s a meaty 18 mph S wind in the afternoon that will just shred the surface. That morning is worth a look, but it's not perfect.

The real winner is the stretch from Monday the 24th through Tuesday the 25th. On Monday morning, we’ve got 5ft from the SSE with a 12-second period and a light WSW cross-off wind. The energy is a solid 796 and the wave comment says “very good.” Then Tuesday the 25th is the standout of the whole period. The morning is dead calm – glassy – with 6ft of SSE groundswell at 13 seconds. The energy is 1010, a solid moderate to strong pulse. It’s going to be clean, lined up, and absolutely firing on the jetties. The afternoon stays glassy at 5ft with good energy. These two morning windows are your best bets. The conditions are clean and the swell has some push, but the period is over 11 seconds, so it will be bigger and more powerful. This is one for the experienced surfers. The water temp is pretty average for this time of year, so nothing wild to report there.

After that, the surf slowly winds down into the second week. Wednesday and Thursday are smaller and the energy drops. There’s a little bump on Friday, but it’s short period and messy. The real long-range promise is for Sunday the 30th, which shows a 7ft E swell with a light cross-off wind and good energy of 873. That one is over a week away, so keep an eye on it, but it has the potential to be another clean day. For the rest of the time, it’s pretty average. This spot needs the winds to behave, and they don’t for the majority of the window. If it’s too windy and lumpy, you might see a few foil boards out there, but for paddle surfing, stick to those bluebird mornings.
