The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ at Molhes de Mampituba over the next couple of weeks.
We’ve got a stretch of surf ahead, but it’s not all gonna be a classic. The water is sittin’ at 61°, which is a touch colder than we’re used to for this time of year – about 3° cooler than average, so you’ll wanna zip up that wetsuit a little tighter.
The real standout window opens up on Sunday, September 6th, and carries into Monday the 7th. That’s when we see a solid pulse of swell from the ENE pushing in around 7 ft to 7 ft. The combined energy is strong, hitting 923 on Sunday morning and 924 on Monday morning. That’s a lot of water moving. The wind is light and offshore, or cross-off, keepin’ things clean. This is the best of the forecast – proper waves for experienced surfers, with that jetty setup holdin’ the shape. Just be aware, with this size, it’s a bit much for the groms.
The first few days, from Wednesday the 26th through the end of August, are a mixed bag. Wednesday morning the 26th offers up a clean 7 ft swell from the SSE with a light cross-off breeze, but the period is a moderate 14 seconds. The energy is high at 1748, but the afternoon gets messy with a cross-shore wind. Thursday the 27th drops off in size, and Friday the 28th sees a shift to a short-period ENE swell at 8 seconds – that’s gonna be a bit lumpy and weak.
We’ve got a few days of poor conditions in between, with lumpy cross-shore winds and weak swell. The weekend of the 30th and 31st shows some promise, especially Sunday morning the 30th with glassy conditions on a 3 ft east swell, but it’s not the big stuff.
Looking further ahead, the second week chills out. Wednesday the 2nd of September has a glassy morning with 4 ft from the SSE, but it’s small. By the 4th and 5th, we’re down to knee-high dribble with poor winds. Stick to the first week of September for the real action.
So, your best bet is the Sunday 6th and Monday 7th – hit it early for the clean, punchy ENE swell. It’s a little on the bigger side, so save your beginner board for another day.
Rusty, signing off.
