The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Molhes de Mampituba over the next couple of weeks.
The first few days are pretty flat out ordinary. Wednesday and Thursday are small and messy, nothing to get excited about. The first real glimmer of something worthwhile doesn’t show up until Saturday the 8th.
That Saturday morning, the 8th, Molhes de Mampituba starts to wake up. Swell comes in at 6 ft from the SSE, with a nice long period of 12 seconds – that’s some proper groundswell energy. The combined energy hits 815 (moderate), and the wind is a clean cross-offshore from the NNE. By the afternoon, the wind goes completely glassy, and the energy bumps up to 926. That’s the standout session of the first week. The river mouth should be offering some tidy, lined-up waves. Just be aware that the crowds are often here, so expect company.
A couple of other decent windows pop up: Monday the 10th has glassy conditions in the morning with 4 ft swell from the S (11 seconds, energy 382), and Wednesday the 12th morning sees a solid 5 ft SSE swell at 12 seconds with a combined energy of 1225, clean cross-off wind. That’s a strong one for experienced surfers.
The real standout, though, is the morning of Tuesday the 18th. That’s next week Tuesday, note the date. The swell jumps to 8 ft from the S, with a period of 9 seconds. The combined energy is a massive 1804 – strong to very strong wave energy. Despite the shorter period, the wind is light and clean from the WNW, keeping it glassy. This is heavy, powerful surf. At 8 ft, it's for experts only. The afternoon turns a bit onshore, but that morning session is the one to circle on the calendar. It’s a long-range call, so keep an eye on the forecasts, but it looks promising.
The rest of the run is a mixed bag of cross-shore winds and dropping energy. There’s a patchy gap after the 12th until the 18th, with only fleeting moments of clean waves. Overall, the best bets are Saturday the 8th and Tuesday the 18th.
Stay safe out there.
Rusty.
