The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s coming down the line for the next couple of weeks.
The main draw is the jetty at Molhes de Mampituba. We’ve got a fairly consistent run of southern hemi groundswell, but the wind is a bit of a character, switching around a lot. The water is sittin’ at 62°F, which is pretty much spot on average for this time of year, so nothing wild there.
The real standout look is Wednesday morning, the 26th of August. The swell is a solid 7ft from the SSE, with a long 14-second period pushing a massive amount of energy – we’re talking 1705 (moderate wave energy). But the beauty is the wind: a light cross-offshore breeze from the NNE. That’s going to have the waves looking clean and lined up. This is for the experienced crew, though; 7ft is getting up there.
Tuesday morning, the 25th, is a solid second option. Swell drops to 5ft from the SSE, but still a clean 12-second period. The wind is light and cross-off again, making for a clean session. It’s a bit smaller, so a good option if Wednesday feels a touch too big.
The rest of the week is a mixed bag. Thursday the 27th morning has a smaller 4ft swell with clean cross-off winds, but the energy drops off. Then Friday the 28th and Saturday the 29th are small and a bit messy with onshore wind changes.
We do have a couple of long-range looks worth keeping an eye on. Tuesday morning, the 1st of September, the swell jumps back up to 8ft from the S, but it’s a bit wind-affected with a cross-shore breeze, making it look marginal. Wednesday morning, the 2nd of September, is more promising: 6ft from the SE, with a clean cross-off wind from the NNE. That’s a solid, clean wave for the more experienced surfer.
After that, it tails off. The first week of September sees the swell drop and the wind turn nasty. The last real glimmer of hope is Sunday morning, the 6th of September, with a small 4ft swell from the S, but the wind is light and cross-off, so it’d be clean for a log or a funboard.
So, for the best of the best, it’s all about Wednesday the 26th of August and Wednesday the 2nd of September. Mark them in your calendar.
Stay safe, keep your wits about you, and I’ll see you in the water.
