The Lowdown
Alright, Rusty here again. Let’s talk Molhes de Mampituba in feet and miles per hour. The water temp is just about normal for the time of year.
Right now, Tuesday and Wednesday are a total mess—onshore winds and chopped-up surf. Combined energy is moderate, but the wind is just not playing ball. Don’t bother.
Thursday morning, September 17th, is where it starts. Light NNE winds, clean as glass, with waves around 3ft from the S, 11 seconds period. That’s a long period groundswell that’ll wrap into the jetty nicely. Combined energy is 265. The standout is the clean conditions. Crowds can be an issue here often, so get in early.
Friday morning the 18th is more of the same—light winds, 3ft from the SSE, 9 seconds, clean. Good for a log. Afternoons get choppy again.
Saturday the 19th gets bigger but ugly. Sunday the 20th is the big one: 8ft from the ENE, 8 seconds, combined energy 1231. Light and clean winds. That’s big, powerful, and for experienced surfers only.
Monday the 21st is marginal, then Thursday the 24th morning gives you 4ft from the E with light winds—clean but nothing like that Sunday peak. Saturday the 26th morning is glassy—dead calm, 5ft from the ENE, 7 seconds. Perfect for a longboard.
Late September 28th sees 8ft from the S with onshore wind—big but messy. Experts only.
The best call is Sunday the 20th September for the biggest clean swell, and Thursday and Friday mornings for smaller, cleaner rides.
Rusty.
