Molhes de Mampituba Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s paddle out and look at what’s coming for the next couple of weeks. We’ve got one spot to focus on, and it’s a bit of a mixed bag.

First off, the water is sitting at 63°F, which is about average for this time of year, so no surprises there.

The overall pattern starts with some small, clean windows but quickly gets knocked around by wind and lumpy conditions. The real standout is a morning session on the 21st of September, where the stars line up properly.

Here’s how it breaks down.

Tuesday 8th September has a decent start. The morning at Molhes de Mampituba is looking clean with a light cross-offshore breeze from the north. The swell is 4ft from the SSE at 9 seconds, and the combined energy is moderate (300). It’s a good, clean option for intermediates, but the afternoon gets messy as the wind swings onshore.

Wednesday 9th is a write-off. The swell drops to 3ft, and the wind is all over the place, cross-shore and cross-on. Not worth paddling out for.

Thursday 10th morning offers another clean window. The wind is light cross-off from the NNE, and the swell is small at 3ft, but here’s the kicker: the period jumps to 15 seconds, making it a long-period groundswell. The combined energy is strong at 415. This will produce some well-shaped, lined-up waves, but it’s small. It’s a river/jetty setup here, so that long-period energy will wrap in nicely, though the size is best for a longboard or a funboard.

Friday 11th is a mess. The morning is surfable but ordinary, and the afternoon turns into heavy rain and a fresh 19 mph cross-shore wind. Forget it.

Saturday 12th sees the swell jump to 7ft from the SSE, but the wind is strong and cross-shore or cross-on. At 7ft, it’s pushing into the expert zone, but with the lumpy chop, it’s more of a kite-surfing setup than a clean paddle session.

Sunday 13th afternoon pumps up the volume with a 8ft SSE swell and a combined energy of 1723, which is very strong. But the wind is onshore from the SSE, making it a messy, powerful beast. Only for the experienced, and even then, it’s a struggle.

Monday 14th is a total loss with moderate rain and onshore wind.

Tuesday 15th morning has a 8ft ENE swell, but again, the wind is cross-shore. The combined energy is strong at 1361, but it’s not clean.

Wednesday 16th is similar, with strong cross-shore winds and a messy 7ft swell.

Thursday 17th morning is a real highlight. The wind turns offshore from the NNW, light at 6 mph, and the swell is 5ft from the south at 9 seconds. The combined energy is moderate (386), and it’s clean. This is a solid session for an intermediate surfer.

Friday 18th morning is another good one. Light cross-offshore wind from the NNE, swell 4ft from the south, but the period is 11 seconds, giving it some extra punch. The combined energy is moderate (429). Clean, lined-up waves.

Saturday 19th morning is glassy. No wind, just a 3ft ENE swell. It’s small, but it’s perfect for a longboard. The combined energy is weak (204), so it’s not powerful, but it’s a fun, cruisy session.

Sunday 20th is just ordinary.

Monday 21st September – THE STANDOUT. This is the one to circle on the calendar. The morning has a clean, light cross-offshore breeze from the north, and the swell is a solid 6ft from the east at 9 seconds. The combined energy is strong (604). This is the best combination of size, clean conditions, and punchy waves in the whole forecast. It’s an excellent session for intermediate to advanced surfers. The river/jetty setup will handle the east swell well, and the crowds here are often present, so expect some company.

Tuesday 22nd morning is glassy again, but with a 5ft SE swell. It’s clean and fun, but not as powerful as the day before.

After that, the forecast fades out with small, poor conditions through to the 23rd.

So, overall, keep your eyes on that Monday 21st September morning session at Molhes de Mampituba. It’s the best on offer. The Thursday 17th morning is also a cracker, but the 21st has the size and the clean wind.

This is Rusty, signing off.
