Molhes de Mampituba Surf Forecast and Surf Report

Alright, let’s talk about what’s in the water at Molhes de Mampituba. This is a river jetty setup, exposed to the swell, and it’s a real mixed bag, but there are a few windows of clean, fun surf if you pick your moments.

The water is sitting at 59°F, which is a solid 5°F colder than normal for this time of year – that’s a very unusual chill, so you’ll want a good thick wetsuit.

We start off with a real gem on Wednesday morning, the 8th of July. It’s glassy, with a light NW breeze, and a clean 3ft S swell rolling in at 11 seconds. The energy is moderate (230). It’s not huge, but it’ll be clean and lined up for the jetties. Perfect for a morning session. The afternoon turns cross-shore and the quality drops right off.

Thursday morning the 9th sees a smaller 2ft ESE swell with a cross-offshore NNE breeze, keeping things clean enough for a surf, but it’s nothing special. The real standout comes on Saturday the 11th of July. The morning has a 4ft ESE swell with a 13-second period, light cross-offshore wind, and strong wave energy (659). The afternoon turns glassy with the same 4-4ft swell and a huge energy reading (701). That Saturday is the clear winner of the first week – clean, a bit of push, and the jetties should be working nicely.

Sunday morning the 12th is also glassy with a 4ft SSE swell, but the afternoon gets wrecked by a strong SW wind. The rest of that week is mostly ordinary, with choppy, cross-shore conditions.

There’s a gap of a few days there with poor surf, but then Wednesday the 15th of July morning brings a tiny 2ft SE swell, glassy, and a very long 13-second period. It’s more of a longboarder’s wave, but it’ll be clean. Then the 16th Thursday morning has a bit more life with a 3ft SE swell, cross-offshore wind, and decent energy (231).

The following week, from the 18th, starts to build. Saturday the 18th morning has a 5ft ENE swell, clean with cross-offshore wind, and solid energy (421). That’s a fun size, but it’s a short period (8s), so it’ll be a bit lumpy. The real highlight of the second week, and possibly the best of the whole run, is Monday the 20th of July. The morning shows a 7ft ENE swell with cross-offshore NNE wind, and very strong energy (825). That’s a proper swell for intermediate to advanced surfers – it’s got push. The period is still short at 8 seconds, so it won’t be as clean as a groundswell, but at that size with clean wind, it’ll be a fun, punchy wave at the jetties.

The 21st Tuesday morning drops back to 5ft from the east, but it’s glassy. Then the 22nd Wednesday is all glassy, with a 4-4ft E swell – that’s a great session for anyone. The 23rd Thursday morning brings a return to a 4ft S swell with an 11-second period, cross-offshore wind, and solid energy (437), a nice way to finish the run.

The standout best is the morning of Monday the 20th of July for the size and power, and Saturday the 11th of July for the cleanest, glassiest conditions with a nice long-period swell. Crowds are often a factor here, especially on the good days, so expect company.
