The Lowdown
Alright, Rusty here again, giving you the scoop for Molhes de Mampituba. It's a river and jetties spot, and the next couple of weeks are a real mixed bag.
Don't get too excited for the first few days. We've got rain, sloppy winds, and weak little waves to start. The energy is low, around 135 on Sunday, so it's not worth paddling out.
The first decent chance comes up on Tuesday, September 1st. There'll be some chest-high swell, around 7ft from the east, with a 9-second period. The wind will be light and cross from the SSW, and the energy bumps up to 635. It's a bit rough, but it's better than nothing.
The first real gem I see is Wednesday, September 3rd. The morning is gonna be clean, real clean. Light offshore winds from the NNE and a nice 4ft swell from the ESE with a 10-second period. The combined energy is a solid 328. That's a good window. The water temp is about normal for the year.
After that, things get messy again with onshore winds until the 7th of September. There's another clean window that Monday morning with 5ft of SE swell and light offshore winds, but it gets blown out later.
Heading into the second week, you get another clean morning on Friday, September 11th, with a 4ft SSE swell and light offshore breezes. A quiet option.
But the main event, the one you need to keep in mind, is Monday, September 14th. The forecast shows a glassy morning. Absolutely no wind. The swell is a solid 6ft from the ENE with a 9-second period, and the combined energy is pumping at 927. That's going to be a proper session. Clean, powerful, and fun. It'll be too big for beginners, but for everyone else, this is the day to be there.
The spot does get crowded, so be there early.
To sum it up, there are a few decent windows, but that 14th of September is your best bet by a long shot.
Rusty.
