The Lowdown
Alright folks, Rusty here. Let’s talk about what’s cooking at Molhes de Mampituba over the next couple of weeks. It’s a bit of a slow start, and there are plenty of days where you’re better off doing something else, but there are a couple of windows where the stars might line up.
Right out of the gate, Monday morning we’ve got some waist-high swell sneaking in at around 4 ft from the south, but with a cross-onshore wind, it’s looking a bit lumpy and messy. Not worth paddling out for. That theme sticks with us for the next few days: small, choppy, and cross-shore winds. The combined energy stays moderate, but the wind just kills it.
Come Wednesday the 16th, the swell bumps up to 5 ft, and the energy jumps, but that’s with a moderate cross-shore blowing 12 mph from the SSW. It’s going to be a rough, bumpy mess. For a river/jetty setup like this, that kind of chop makes it look more interesting for the kite crew than us paddle surfers.
Now, Thursday the 17th morning is the first real glimmer of hope. The morning brings a clean, 4 ft SSE swell with a nice long 11-second period and a light cross-offshore breeze from the NNE at 9 mph. That’s a proper window for a few fun ones. The energy is moderate. The period is long enough to hold shape, and the winds will clean it right up. The water temp is feeling about average for this time of year, which is fine.
The standout of the whole outlook? That has to be Sunday the 20th morning. We get a 6 ft easterly swell with a 9-second period and, get this, almost no wind – just a slight air from the NNE. The combined energy is strong, and the conditions are described as clean. That’s the session to circle on your calendar. The easterly direction isn’t the absolute optimum for the break, but with the size and the glass, it’s going to be the best we get. Keep in mind, crowds are likely here, so get there early.
The morning of Monday the 21st still has some leftover 5 ft E swell, but the wind swings onshore from the south, bringing a light chop. It’s still surfable, but not as good as Sunday. Things get marginal for a few days after that, with heavy rain and onshore wind ruining the party midweek.
Then, on Thursday the 24th morning, it goes completely glassy with a 4 ft east swell. If you’re up for a clean but smaller day, that’s a good option. The rest of the second week looks smaller again, with energy dropping and winds staying messy. There’s a mention of clean conditions on Friday the 25th morning, but with only 3 ft of swell, it’s tiny. The Tuesday the 29th morning brings a punchy 5 ft east swell, but with a cross-shore wind, it won’t be clean.
So to sum it up: the first week is mostly a write-off, but Sunday the 20th morning is the one to aim for. Thursday the 24th morning is a sneaky glassy backup plan. The rest is pretty ordinary.
Rusty.
