The Lowdown
Alright, grab your wettie and listen up. This is Rusty, giving you the rundown for the home break at Molhes de Mampituba.
We’re in for a strange run. The next couple of days are a write-off, with messy cross-shore winds and lumpy, weak surf. Friday and Saturday are best spent doing literally anything else. It’s not until Sunday the 16th that things finally start to turn.
The first real window we’ve got is the Sunday morning session. We’ll see a jump in size to 7ft, but it’s a short-period easterly windswell. The saving grace is a light cross-offshore breeze that’s going to keep the faces reasonably clean. It’s not perfect, but it’s the first time the ocean will look like a surf spot. The energy is moderate at 1142, so there’s some push behind it. This is for the more experienced crew; 7ft of short-period swell on the jetties can be a handful.
Monday the 17th is the standout of the whole stretch. The swell is still up there, 8ft from the ENE, but the wind drops out completely. We’re talking clean, glassy conditions for the morning, and the afternoon turns truly glassy with the wind going dead calm. The surface is going to be as smooth as it gets. Combined energy is strong at 1351. If you can get out there, this is the day to do it. The water temp is sitting at 63°F, which is pretty much spot on for this time of year.
After that, the ocean just dies. The surf drops right off for the rest of the week. We’ll see a few tiny, weak pulses, but honestly, from Tuesday the 18th through to the 23rd, there’s almost nothing worth paddling out for. We’re talking small, weak, and mostly onshore junk. It’s a real flat spell, which is a bummer after that Monday session.
We get a glimmer of hope late in the run. Check out the 24th and 25th. The swell builds back up on the 24th, the wind goes glassy in the afternoon, and the 25th looks clean again with light offshore winds and head-high-plus surf around 6-6ft. The energy is moderate, but the quality looks decent. These are the ones to watch for in the second week.
So, the game plan is simple: hit it hard on Monday the 17th, then sit tight and wait for that pulse around the 24th and 25th. It’s going to be a quiet fortnight otherwise. The good news is this place is fairly consistent, so a flat spell rarely lasts too long, and the long-range forecast is showing signs of life.
Rusty, signing off.
