The Lowdown
Alright, Rusty here again with the same outlook for Molhes de Mampituba, but in feet and knots for the old-school crew.
It's a river/jetty setup that's fairly consistent, exposed to the south and southeast, and it likes an offshore from the NW. We've got some proper windows coming up, but we gotta be smart about it.
We kick off on Sunday, August 23rd with some real size. The morning is excellent for experienced surfers: a clean 6ft swell from the S, period at 12 seconds, and a light cross-offshore breeze from the WSW at 6 knots. Water temp is about 64°, right where it should be. The combined swell energy is strong at 1011, so there's plenty of grunt. The afternoon goes to crap with the wind swinging SSW and picking up, so get your session in early.
Monday the 24th is a dud. The morning is clean enough with a 8ft SSE swell (14s) and light SW cross-off wind, but the forecast says it's marginal with questionable tide. Afternoon gets choppy with a cross-onshore breeze. Skip it.
Tuesday the 25th sees the swell drop to a cleaner 5ft from the SSE (12s). Morning has a light N cross-off breeze, and it's looking very good for a fun session. The wave energy is moderate at 680. Afternoon gets messy again with an ENE cross-breeze.
Now, Wednesday the 26th is a standout. Morning session is looking excellent for experienced surfers with a solid 7ft SSE groundswell (14s) and a light NNE cross-off breeze at 9 knots. That's a clean, lined-up wave with strong energy (1709). The longer period means better shaped waves. If you've got the skill, this is your window.
Thursday the 27th is another good morning call. Swell drops to 4ft from the SSE (13s) with a light NNE cross-off breeze. Very good, clean conditions with moderate energy (936). A great day for the intermediate crew.
Friday the 28th is interesting. The swell direction swings to the ENE at 6ft (9s), but the wind goes totally glassy in the morning. It's a shorter period windswell, but with zero wind, it'll be clean as a whistle. Wave energy is moderate (555). Afternoon holds clean with a light cross-off from the NNE.
Saturday the 29th and Sunday the 30th both have glassy mornings with 4ft and 4ft E swells. The energy is low (256 and 326), but clean conditions make it worth a paddle on a small board.
We hit a flat spot into September. Monday the 31st has some bumpy 6ft ENE swell with moderate cross-shore wind. Tuesday the 1st is a total write-off with poor conditions and a messy 3ft swell. Avoid it.
Then we get a big one on Wednesday, September 2nd. The morning has a clean 10ft S swell (11s) with a light SW cross-off breeze. The wave energy is very strong at 2881. However, that size is too big for this break. It's a "too big" warning. Only for the most experienced. The afternoon drops to 6ft but with an onshore wind.
Thursday the 3rd recovers nicely with a clean 5ft SSE swell (10s) and a light NNE cross-off breeze. Very good conditions for an intermediate session.
The final few days into the second week are a mix of smaller, shorter-period swells. Friday the 5th and Saturday the 6th have some clean morning windows with 6ft and 5ft ENE swells, but the period is short (7s), so expect weaker, lumpier waves. Sunday the 7th is looking marginal again.
Best Bets: Wednesday morning the 26th is the standout for the experienced crew: clean, strong, long-period 7ft SSE groundswell. For the intermediate surfer, Thursday morning the 27th is your pick: clean, 4ft SSE, light winds. The glassy mornings on the 28th, 29th, and 30th are also worth a look if you just want to get wet on clean, smaller waves.
Stay safe out there.
Rusty.
