The Lowdown
Alright, Rusty here, let’s talk about what’s cooking at Molhes de Mampituba over the next couple of weeks.
We’ve got a bit of a slow start, with the first real chance to get wet not showing much for the first few days, but things start to build.
Friday the 11th kicks off with some small, short-period swell, but the wind is messy. It’s not worth rushing in for. Saturday the 12th sees a pulse of 7ft swell from the south, but it’s cross-shore and a bit choppy. That’s more of a training session than a classic day.
By Monday the 14th afternoon, things start to look up. We get a clean, cross-off breeze with a 5ft swell from the east-northeast, and the combined energy is solid (720). That’s a good sign – the waves will have some push, and the wind is working with us. This is a good window for intermediate surfers. Tuesday morning the 15th, it goes glassy with a 4ft easterly swell. The water temp is about average for this time of year, nothing wild.
The standout is shaping up for Thursday the 17th morning. We’ve got a 6ft swell from the south-southeast, but the period jumps to a very long 13 seconds – that’s proper groundswell. The combined energy reads 1008, which is strong. The wind is cross-off and clean. This is a day for the river jetty to really line up. Just a heads up, the long period means it might wrap a bit straight at the beach, but at a jetty setup like this, it’s a dream. The crowds are often here, so you’ll have company, but the quality will be worth it.
Friday the 18th morning is another clean one, with 5ft from the east-northeast and light cross-off wind (553 energy). A solid, fun option.
Looking into the second week, Saturday the 19th morning goes glassy with 5ft easterly swell. Clean but not huge. Sunday the 20th is glassy all day with 4–5ft easterly swell, just easy cruising. Then we get another little run of glassy conditions on Wednesday the 23rd afternoon and into the 24th. The 25th has a 5ft south swell with a long 11-second period but strong wind, so it’s more of a tricky session.
Overall, the best on offer is Thursday the 17th morning. Long period, solid energy, clean wind. Monday the 14th afternoon and Friday the 18th morning are also very good. The rest is mostly small or messy.
Rusty.
