The Lowdown
Alright, let’s talk about what’s cooking at Molhes de Mampituba.
It’s gonna be a bit of a mixed bag for a while, but there’s a couple of days late in the second week that are going to fire. The water temp is around 64°, which is pretty normal for the season.
We’ve got a little something on Wednesday the 12th. A 5 ft swell out of the SSE with a 12-second period, and a light offshore breeze from the NNE will keep it clean. The energy is moderate (768). It’s a decent little intro, but it’s not the main event.
From Thursday the 13th, the wind turns onshore and it gets messy. We’ve got a run of days with poor wind and short-period swell, with waves hitting 8 ft by Saturday the 15th, but with a 8-second period and junk wind. Not worth it.
The whole of the second week is pretty average until we hit the 23rd. On Sunday the 23rd of August, the morning session is the one. We’re looking at a clean 7 ft swell from the south, a long 12-second period, and a light cross-off breeze from the NNE. The energy is pumping (1384). This is for the experienced crew only—that 7 ft is no joke—but for those guys, it’s going to be epic.
And if that wasn’t enough, Monday the 24th morning is also a standout: 7 ft of swell from the SSE, a 13-second period, and again, a light cross-off from the north. Energy is strong at 1242. Two mornings of absolute gold for the guys who can handle it.
After that, it fades out into small, weak swell and onshore wind. So there you have it: a lot of average days, but two real gems on the 23rd and 24th to make it all worth it.
