The Lowdown
Alright, folks, Rusty here. Let's have a look at what the next couple of weeks are serving up for Molhes de Mampituba. It’s a bit of a mixed bag, so let’s get into it.
The opening stretch is pretty grim. We're looking at a few days of small, weak, and junky surf. The water’s sitting at 62°, which is a bit colder than normal for this time of year, so you’ll want the extra rubber. Wednesday the 9th is a write-off, with tiny, onshore-wrecked waves. Thursday the 10th cleans up a little in the morning with a cross-off breeze and a touch more energy (410), but it's still small and the afternoon turns to junk. Friday is no better; a short-period, weak swell is there but the conditions are just ordinary. So basically, for the first few days, you might as well stay home and watch the cams.
Then we get a bit of a pulse. Saturday the 12th sees a bigger swell jump to 7ft, but it’s coming with a strong onshore wind, making it a messy, bumpy mess. The energy is there (662), but it's unsurfable in any pleasant way. Sunday morning the 13th, however, is where it’s at. The wind drops to glassy, and we have a clean 5ft of SE swell with moderate energy (477) – that’s your window for a proper session if you can get out early before the onshores kick in. That's the pick of the first week for sure.
After that, the middle of the week turns nasty again with strong winds and cross-chop making everything a battle. Monday and Tuesday are big writes-offs. It’s not until Wednesday the 16th that we see some serious size, with 6-6ft of swell and significant energy (850-1071), but the conditions are still questionable with onshore and cross winds. It’s big, but it won’t be pretty.
Now, for the standout. The forecast is pointing at Thursday morning the 17th and especially Friday morning the 18th as the real jewels. Thursday the 17th has that lovely cross-off wind, clean conditions, and a solid 5ft of SSE swell with a nice 11-second period (521). The energy is moderate, but it will have shape. But Friday the 18th is the one. The wind is completely calm and glassy with a clean 3ft of SSE swell (506). It's small but perfectly clean. For a river/jetties setup like this, that is going to be the most fun you’ll have all period. Mark your calendar for Friday morning.
After that, we fade out. The weekend of the 19th and 20th drops right back off, and we are back to long flat spells. There is a glimmer of hope on Monday the 21st with a clean 6ft of easterly swell, but it's likely to be a bit raw and the wind will be swinging around. The energy is low (314) and the period is short (7 seconds). It’s a promise, not a guarantee.
So, to wrap it up: go get some on Sunday morning the 13th, but the real winner is the clean, glassy surf on Friday morning the 18th. Don't get too excited about anything else.
Rusty out.
