Molhes de Mampituba Surf Forecast and Surf Report

G’day, I’m Rusty. Let’s have a look at what’s coming up at Molhes de Mampituba.

The first real surf we’ve got on the cards kicks off on Monday morning the 17th of August. It’s not a day for beginners though – we’re looking at a solid 7ft of ENE swell with an 8-second period, which is a bit short and dumpy. The energy’s pumping hard at 1070, so it’s a powerful, heavy wave. Wind’s coming out of the NNE at 9 mph, so it’s cross-offshore, keeping it reasonably clean, but this is one for the experienced crew only. Crowds are often around here, so expect company.

Tuesday morning the 18th is a good shout – glassy conditions with a touch of WNW breeze at just 3 mph, and the swell drops to 6ft from the NE with 8 seconds. Still a bit short, but the combined energy is 648, so there’s plenty of push. The glassy wind means it’ll be clean and fun for intermediates.

By Wednesday the 19th, the swell fades to 3ft from the ENE, period 8 seconds, with glassy conditions in the morning. It’s surfable but pretty ordinary with only 133 energy. Thursday the 20th sees a drop to 2ft ENE swell in the morning, but there’s a glassy window in the afternoon with a 4ft E swell and 7-second period. Still ordinary, but you could get a few.

Friday the 21st brings a bump in size – 5ft SSW swell with a 9-second period and moderate 12 mph WSW cross-offshore wind. Energy’s at 474, but the conditions are marginal. Saturday the 22nd is similar, 5ft from the S at 8 seconds, but the 16 mph SSW wind creates a cross-chop.

The standout window starts Sunday morning the 23rd of August. Glassy WSW wind at 3 mph, a clean 6ft S swell with a nice 11-second period, and 697 combined energy. This is the best-looking session of the whole run – clean, decent-sized, proper groundswell. The afternoon gets messy with 8ft S swell at 12 seconds, but the 12 mph SW wind chops it up and it’s only for experts.

Monday the 24th morning is another cracker – 7ft S swells with a 12-second period and 1461 energy, with a light 6 mph W cross-offshore breeze. Excellent conditions for experienced surfers again.

From Tuesday the 25th through to the end of the month, the size sits between 4ft and 6ft, mostly from the S or SSE, with periods ranging from 7 to 12 seconds. The problem is the wind – mostly cross-off or with some glassy windows, but the ratings drop off. There are a few bright spots: Tuesday morning the 25th has 5ft SSE swell at 11 seconds with a clean NNE breeze, and Wednesday the 26th morning has 4ft S swell at 10 seconds with gentle cross-offshore wind. But overall, it’s a mixed bag with plenty of poor afternoons.

The very best of the 16 days is undeniably Sunday morning the 23rd and Monday morning the 24th – clean conditions, decent-to-solid groundswell from the S, and that long 11 to 12-second period will make the waves hold up nicely, especially around the river mouth at Molhes de Mampituba. Crowds are often, so get there early.

Signing off – Rusty.
