The Lowdown
G'day, Rusty here. We've got a bit of a slow start on our hands at Molhes de Mampituba, but there are some proper windows of clean surf if you're patient. The water's sitting at 63°F with an anomaly of -0.4°F, so about average for this time of year.
The first real glimmer of hope comes Thursday morning, the 3rd of September. It's not massive, but a 5ft swell from the SE with an 11-second period and glassy conditions – that's a serious treat. The water will be dead flat, no wind ripples. The combined energy is moderate at 548. It's a river/jetty setup, so that longer period groundswell should wrap in nicely. Just a heads up, crowds are often here, so get in early.
Friday the 4th and Saturday the 5th are a write-off with poor conditions and onshore winds. Sunday the 6th looks messy too, with strong cross-shore winds and a lumpy sea state.
Then we get a nice run. Monday morning, the 7th of September, has a clean 4ft S swell with an 11-second period. The wind is light offshore from the WNW, so the faces will be clean. The energy is moderate at 403. Then Tuesday morning, the 8th of September, is a standout with a 4ft SSE swell and a clean offshore breeze from the NNE. The combined energy bumps up to 619, so there's a bit more push. And Wednesday morning, the 9th, keeps the run going with a 5ft swell from the ENE and light offshore winds. The energy is moderate at 534.
After a bit of a lull with onshore winds and smaller surf through the 10th to the 12th, the following week has some promise. Sunday morning, the 13th of September, brings clean 4ft ENE swell with a light offshore. Monday morning the 14th is similar but smaller at 3ft.
But the real standout in this entire 16-day window is Thursday morning, the 17th of September. This is the one for the experienced crew. We're looking at a solid 7ft swell from the S with a 10-second period. The combined energy is strong at 1181. And the best part – light offshore winds from the NNE keeping it clean. That's proper surf. At 7ft, it's a bit much for beginners, so this one's for the lads and lasses who know what they're doing.
The afternoon of the 17th drops off a bit with a cross-shore wind and marginal conditions. Wednesday morning the 16th has a clean 3ft S swell with an 11-second period and light offshore wind – a nice little finisher to the period if you missed the earlier windows.
Overall, there's a few sessions to get excited about, but Thursday the 17th is the one to circle on the calendar.
Rusty.
