Molhes de Mampituba Surf Forecast and Surf Report

G’day, Rusty here. Let’s have a honest look at what’s coming up for Molhes de Mampituba. This is a river/jetty set-up, exposed to the swell, and it’s been a bit of a slow burner lately. We’re in for a long patch of pretty ordinary conditions before something proper shows up in the second week.

Right now, from Wednesday the 29th of July onwards, there’s nothing worth paddling out for. That afternoon shows a tiny 2ft south swell with a 10-second period and cross-onshore winds. The water’s 64°, which is about normal for this time of year, no big anomaly to mention. Energy’s weak at 104, and it’s just poor surf. You’ll be battling chop and not much else.

Thursday the 30th is a mixed bag. The morning glass-off with a 2ft south swell and no wind is the best you’ll see for days – clean, but tiny. By afternoon, the wind swings and the quality drops.

Friday the 31st morning offers a bit more height at 4ft from the ENE, period a short 6 seconds, but the cross-off wind cleans it up. It’s only marginal though, and the afternoon gets blown out by a fresh 30 km/h cross-shore.

Saturday the 1st of August morning has a bigger 7ft NE swell, period 8 seconds, and clean cross-off winds. This is actually the one decent window in the first week. It’s intermediate-friendly but pushing the limits for beginners. Moderately strong energy at 866, but the afternoon falls apart with onshore wind. If you can get out Saturday morning, it’s your best bet this side of the forecast.

After that, it’s a flat spell. Sunday the 2nd through to Tuesday the 4th are all small, weak, and mostly messy. Swells under 3ft with cross or onshore wind. Wednesday the 5th morning goes glassy again with a 2ft south swell, but it’s tiny and just ordinary.

Now, here’s where things get interesting. Thursday the 6th of August morning – finally some hope. A 3ft SSE groundswell with an 11-second period, light cross-off wind from the north, and clean conditions. Energy’s moderate at 301. This is a standout for the period: good shape, clean, and not too big. Best for intermediate surfers, and the river jetty setup should handle that longer period nicely.

Friday the 7th morning is also clean with 2ft SE swell and a similar 11-second period, but smaller. Still worth a look.

Then we hit a big gap of no-good options from Saturday the 8th through Monday the 10th morning. Lots of onshore wind and messy small waves.

But hold on – Monday the 10th afternoon brings a sudden jump: 7ft SE swell with a 7-second period and cross-onshore wind. Not great quality, but energy jumps to 713. Then Tuesday the 11th morning goes 8ft from the east, 8-second period, light cross wind, and energy hitting 1497. That’s some proper grunt, but it’s marginal and the period is short – might be lumpy and hard to handle.

The real standout is Wednesday the 12th of August morning. Massive 12ft ESE swell with a 9-second period, glassy conditions thanks to light NW wind, and energy screaming at 4256. This is for experienced surfers only – 12ft is way too big for anyone else. The river/jetty might actually handle this size if the direction is right, but it’s serious. By afternoon, it backs off to 10ft but stays big.

Thursday the 13th of August morning is the pick of the big stuff: 8ft east swell, 9-second period, light cross-off wind from the NNE, clean, and energy at 2137. It’s still expert-only, but the conditions are excellent. This one’s a true standout for the whole stretch.

Overall, Saturday morning the 1st of August is your smart call for smaller, cleaner fun. For the big wave crew, Wednesday the 12th and Thursday the 13th mornings are the ones to circle – just be ready for size and power.

Rusty.
