The Lowdown

Right, mate, Rusty here. Let’s talk about what’s cooking at Molhes de Mampituba.

We’ve got a solid run of surf ahead, but it’s not all perfect. The first window kicks off strong on Saturday, July 18th, with a clean 7 ft swell from the ENE, period of 9 seconds. The wind is a light cross-off, and the water is sitting at 60°, which is a bit colder than normal for this time of year – a good 3° cooler than average, so grab a thicker wetsuit. The combined energy is moderate (946). This is a standout session, nice and clean, and the river/jetties setup should be handling it well.

Sunday morning, July 19th, drops to a 6 ft NE swell, still a cross-off wind, but the score dips a little. The afternoon cleans up again with a 6 ft ENE swell and a glassy 3 mph cross-off, making for some very good surf. That’s worth a paddle.

Monday, July 20th, starts off okay with a 4 ft ENE swell and light cross-off winds, but the afternoon turns to junk – rain showers and a cross-on wind ruin the shape. From Tuesday, July 21st, through Friday, July 24th, the surf gets pretty average. Swell drops to 3 ft or less, and the wind is mostly cross or cross-on, creating messy conditions. The combined energy stays weak (under 300).

Things pick up again on Friday, July 24th, morning with a clean 4 ft SE swell and light cross-off wind. Saturday, July 25th, morning is also worth a look with a clean 3 ft ESE swell, but it’s small.

Now, here’s the real highlight. Sunday, July 26th, morning is a sneaky gem – glassy conditions with a 2 ft S swell, but a long period of 11 seconds. That’s a groundswell, and on a river/jetty setup, it’ll wrap in with some real push. The combined energy is moderate (214). It’s small, but it’ll be clean and fun.

Monday, July 27th, morning is the absolute standout of the entire 16-day window. The swell bumps up to 6 ft from the ENE, and the wind is dead calm – glassy. Combine that with the quality of the break, and you’ve got a session that’s hard to beat. The combined energy is moderate (516). This is the one to circle on the calendar. Crowds are often here, so you’ll have company, but for waves like that, it’s worth it.

Tuesday, July 28th, morning has another clean 6 ft ENE swell, but the wind is a bit stronger, still cross-off, so it’s good but not as epic as Monday.

The tail end of the period, from Wednesday, July 29th, through to August 2nd, has some decent moments. The morning of Wednesday, July 29th, has a clean 4 ft ENE swell with an offshore wind. Friday, July 31st, morning has a clean 4 ft E swell. And Saturday, August 1st, morning brings a 5 ft SSE swell with a gentle offshore – clean and punchy. The last day, Sunday, August 2nd, morning has a clean 3 ft SSE swell with a 10-second period, which will be a nice, clean finisher for the run.

Overall, the best of the best is Monday, July 27th, morning, with Sunday, July 26th, morning as a close second for that glassy groundswell. The first week is your best bet, with the second week offering smaller, cleaner windows but less power.

Rusty.
