Molhes de Mampituba Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get straight into it. We’ve got a mixed bag coming up at Molhes de Mampituba, a river/jetty setup that needs the right conditions to really fire. The near-term is pretty grim, but there’s some serious size and power building for the second week that could make it all worthwhile.

The first few days are a write-off. The swell is small and weak, and the wind is messy. Wednesday the 22nd morning is glassy with a tiny 4ft Easterly swell, but it’s just not enough to get excited about. The combined energy is weak at 197, and it’s a “surfable waves but very ordinary” kind of vibe. After that, the wind swings onshore and the whole thing just falls apart. We’re looking at a gap of poor conditions through Thursday and Friday. Thursday morning the 23rd does see a jump in size to 7ft from the SSE, but the cross-shore wind is making it a choppy mess, and the energy is moderate (878). It’s not worth paddling out for.

We get a small window of hope on Saturday morning the 25th with a glassy start and a 6ft ESE swell, but the wind is already fiddling with it. Sunday morning the 26th is glassy again with a 4ft swell, but it’s just not enough push. The real turning point is over a week away.

The standout is clearly the first weekend of August. From Saturday the 1st, things get serious. The morning is glassy, with a 8ft ENE swell and strong combined energy at 782. This is solid, clean surf. The afternoon stays glassy with a 8ft E swell and even more energy (817). This is the best on offer in the whole run – consistent, powerful, and clean. The swell direction is a touch east of the optimum SE, but the conditions are so good it won’t matter.

After that, the swell keeps building, but it gets big. Sunday the 2nd sees 10ft E swell, but the cross-shore wind is howling at 12 mph, and the energy is extreme (2018). This is too big and blown out for the jetty. Monday the 3rd is a better bet for experienced surfers: 8ft E swell with a clean cross-off wind and very high energy (1693). The period is 11 seconds, so real groundswell punch. Tuesday the 4th morning is similarly big and clean, but 10ft is expert-only territory.

The real cherry on top is Wednesday the 5th and Thursday the 6th. Wednesday morning is glassy, 7ft ESE swell with a 11-second period, and energy at 1121. This is excellent for experienced surfers. Thursday morning the 6th is the same: glassy, 7ft ESE swell, a very long 14-second period, and massive energy (1727). The long period will make it a bit walled-up at the beach, but for a river/jetty break like this, it’s going to line up beautifully. This is a serious session if you’ve got the skills.

So, to sum it up: the next week is mostly a washout. The best bet by a long shot is the glassy, powerful swells arriving from Saturday the 1st, with Wednesday the 5th and Thursday the 6th mornings being the absolute standouts for the experts. Don’t bother with the rest.
