Molhes de Mampituba Surf Forecast and Surf Report

Alright, let’s talk about Molhes de Mampituba. This is a river/jetties setup, so it’s a bit more fickle than a straight beach, but when it’s on, it can be a lot of fun. The water temp is about average for the time of year, so no need to reach for the thickest rubber just yet.

The forecast starts with a bit of a whimper on Monday, 3rd August. Morning brings a tiny 2ft swell from the ENE with a weak 8-second period, and a cross-off wind from the NNE at 9 mph. The combined energy is only 98, so it’s weak. It’s surfable, but it’s not going to get the heart racing. The afternoon goes flat with a 1ft SSE swell and a cross wind, making it pretty poor.

Tuesday, 4th August, is where we start to see a pulse. The morning is a real standout early option. The wind goes glassy, absolutely dead calm from the north, and the swell bumps up to 3ft from the SSE with a 12-second period. The combined energy hits 286 (moderate), and the conditions are glassy. That’s clean, lined-up little waves perfect for an intermediate. The afternoon gets messy with a cross-on wind and rain showers, so get out early.

Wednesday, 5th August, is another morning of glassy conditions from the WNW, but the swell is a touch smaller at 3ft and the period drops to 10 seconds. The energy is 150. It’s surfable, but ordinary. The rest of the week is a bit of a mixed bag of small swell and onshore winds, with Thursday and Friday offering only small, cleanish waves for the early birds.

The Big Call – Saturday, 8th August. This is the best on offer in the first week. The afternoon delivers a solid 4ft swell from the south with a very long 16-second period. The combined energy rockets to 912 (strong). The wind is a light cross-off from the north at 6 mph. The forecast says “expect very good surf conditions.” That long period groundswell will wrap nicely into the jetty, giving proper, powerful waves. It’s a standout. Just be aware, crowds are likely here, so get in position early.

Sunday, 9th August, is a write-off. A fresh breeze from the SSW at 19 mph with a cross wind and rain tears the surface apart. The swell is over 4ft, but the chop will be awful.

We get a big, solid pulse on Tuesday, 11th August. The morning swell is 8ft from the SSW, with a cross-off wind and a combined energy of 1817 (very strong). The forecast says it’s marginal, but it’s clean. The afternoon though, the swell hits 10ft from the south. That’s big. The energy is 2955 (very strong). For a river/jetty break, at this size, it’s going to be a washing machine. Only for experts, and even then, it’s on the edge of being too big and dangerous.

Wednesday, 12th August, is a much better proposition. The morning is glassy from the WNW, with a 6ft south swell at 11 seconds. The energy is 676 (moderate to strong). The forecast says “expect very good surf conditions.” This is a true standout for the second week. The wind is glass, the swell is solid but not crazy, and the period is good. This is a proper session.

Thursday, 13th August, is another good morning with a glassy north-northwest wind and a 4ft SSE swell at 11 seconds. Energy is 408. Good, clean, fun waves.

The run into the following week gets bigger again. Saturday, 15th August, has a messy onshore wind, but Sunday, 16th August, morning is a standout. The wind is a light cross-off from the NNW, and the swell is 6ft from the east at 8 seconds. The combined energy is 726 (moderate to strong). The forecast is “very good surf conditions.” It’s a shorter period, so it’ll be a bit crumbly, but clean.

Monday, 17th August, morning is also a solid call. The swell is 7ft from the east, with a cross-off wind and a combined energy of 843 (strong). It’s clean and powerful. The afternoon, however, the swell hits 10ft again, which is too big for this spot.

Tuesday, 18th August, the forecast shows an 12ft swell from the ENE. That’s enormous. The energy is 3116 (very strong). It’s clean, but it is strictly for experts only, and the guidance says it’s too big for the break. You’d need a death wish, not a surfboard.

So, the standouts are clear: Saturday, 8th August afternoon for the quality long-period south swell, and Wednesday, 12th August morning for the glassy, solid, and clean conditions. The Sunday, 16th August morning and Monday, 17th August morning are also very good, cleaner options.
