The Lowdown

Alright, let’s get into it. This is Rusty.

First up, we’ve got a bit of a flat start here. The surf’s pretty average for the next few days at Molhes de Mampituba. It’s a river/jetty setup, exposed to the swell. Water temp is sitting at 62°, which is a bit colder than normal for this time of year—nothing too crazy, but you’ll want a decent wetsuit.

Sunday 13th September is a write-off. We’ve got a 4ft SSE swell with a short 7-second period, cross-on S wind at 16 mph, and it’s choppy as hell. Combined energy is moderate at 255. Not worth paddling out.

Monday 14th September morning shows a slight improvement with a 4ft S swell and 9-second period, but it’s still cross and marginal. The energy is moderate (282). The afternoon drops to 2ft and cross-on again. Still no good.

Tuesday 15th September is more of the same—4ft SE swell, 8-second period, cross-on wind, and choppy. Combined energy moderate at 283. Not your day.

Wednesday 16th September morning has a 5ft S swell, 8-second period, but it’s cross-shore with a moderate breeze and a cross-chop. Energy is strong at 552, but the quality’s not there. Afternoon is worse.

Now, Thursday 17th September morning is where things start to look up. Clean conditions with a light NNE cross-off breeze. Swell is 5ft from the SSE with an 11-second period—decent groundswell, though it’s a bit long for a beach break, so it might be better on the jetty or points if there were any. Energy is strong at 428. This is a solid session if you can get out.

Friday 18th September morning is clean again, light NNE cross-off, 3ft SSE swell with a 9-second period. Energy moderate at 295. Expect good surf conditions.

Saturday 19th September morning is a standout. Clean with a light NNE cross-off breeze. Swell bumps up to 6ft from the ENE, 7-second period—short period but decent energy at 542 (strong). This is one of the best on offer. The afternoon gets messy with fresh cross-shore winds, so get out early.

Sunday 20th September morning is clean again, light cross-off, 5ft E swell with a 9-second period. Energy strong at 402. Good conditions.

Monday 21st September morning is glassy. That’s a major positive. Swell is 4ft from the E, 9-second period. Energy moderate at 276. This is a great session for the intermediate surfer—clean and easy.

Tuesday 22nd September is back to marginal with moderate rain and onshore winds.

Wednesday 23rd September morning is another standout. Glassy conditions, 5ft ESE swell with a 9-second period. Energy is very strong at 672. This is the best on offer in the whole outlook. Get on it.

Thursday 24th September morning is clean with a light cross-off, 3ft E swell, 8-second period. Good for a quick session.

Friday 25th September morning is clean again, light cross-off, 4ft E swell with a 9-second period. Energy moderate at 420. Good conditions.

Saturday 26th September morning is a standout. Clean with light offshore WNW wind. Swell is 6ft from the E, 7-second period. Energy strong at 533. Another excellent session.

Sunday 27th September has good conditions in the morning with clean cross-off wind and 4ft E swell. The afternoon goes glassy—another good option.

Monday 28th September afternoon is glassy with a 4ft E swell, 8-second period. Good conditions.

Overall, the best windows are the mornings of 23rd September (glassy, 5ft ESE, very strong energy) and 19th September (clean, 6ft ENE, strong energy). The river/jetty setup works well with the longer period swells. Keep an eye on the long-range stuff—it’s promising.

Stay safe, Rusty.
