The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ at Molhes de Mampituba for the next couple of weeks.
Honestly, the first real action doesn’t kick off until Monday the 20th, and even then it’s pretty tame. We’re looking at a bit of a slow start for a few days. Monday morning will see some small 4ft ENE swell, with a moderate wave energy of 203. The wind is a light cross-off from the NNE, keeping things clean, so you can get a few rides in, but it’s nothing to write home about. The water temp is sitting at 62°, which is pretty standard for this time of year.
Tuesday the 21st sees the swell drop a touch to 3ft, but the wind goes glassy in the morning. That’s a rare treat for clean conditions, even if the waves are small. The combined energy stays modest around 152. It’s surfable, but ordinary.
There’s a bit of a lull on Wednesday the 22nd and into Thursday the 23rd, with messy winds and a bump in swell that’s mostly wind-affected and choppy. Not worth the paddle, honestly. Friday the 24th morning looks more promising again with a clean 5ft SE swell and 479 combined energy – that’s a moderate pulse – and light cross-off winds from the north. That’s a decent window for an intermediate surfer.
Saturday the 25th morning is similar, with 5ft ESE swell and clean conditions. A good shout for a weekend session.
Then we get a standout window on Sunday the 26th. The morning swell jumps to 7ft from the SE with 984 combined energy – that’s strong wave energy. It’s big enough that beginners should sit this one out; this is for the experienced crew. The wind is cross-off from the WSW, so it’ll be clean. This is the best on offer so far. Watch out, it’s a big, powerful groundswell with a 10-second period, meaning solid, well-shaped waves but with long lulls between sets. The afternoon gets a bit choppy so hit it early.
Another good call is Monday the 27th morning. The swell backs off to 5ft from the ESE, but the wind goes dead glassy from the NNW – perfect. Combined energy is 418, so there’s still some punch. A great day for a long session.
The middle of the week from the 28th onward drops off pretty quickly. Swell sizes drop under 3ft, winds get stronger, and the combined energy fades into the 90s to 200s. It’s mostly poor or marginal conditions through the end of July. Not worth getting excited about.
Now, looking way ahead – over a week out – there’s a promising pulse around Saturday the 1st of August. Saturday morning shows a 6ft ENE swell with a combined energy of 750, and the wind is glassy from the southwest. That’s a big, clean swell, but it’s going to be a bit much for beginners – stronger, powerful. It could be the second big highlight of the run, but at this range, treat it as a promising maybe. Sunday the 2nd also has a nice morning with 6ft ENE swell, light cross-off winds, and 730 energy – again solid for experienced surfers. Things fizzle out again after that.
So overall, the standouts are Sunday the 26th morning for the biggest, most powerful swell (7ft SE, clean) and Monday the 27th morning for the glassy, clean conditions on a solid 5ft swell. For the long-range, keep an eye on Saturday the 1st of August morning for another strong, glassy pulse.
Since there’s only one break on offer here, and it’s a river/jetties setup that’s fairly consistent, the quiet days are just part of the deal. Crowds are possible here “often,” so on the better days, expect company. The optimum swell direction is SE, which lines up nicely with the bigger pulses on the 26th and 1st. Get in the water when you can.
Rusty.
