The Lowdown
Alright, Rusty here, checkin' in from the local stretch. Let's talk about what's on the menu for the next couple of weeks down at Molhes de Mampituba.
We're lookin' at a mixed bag, with some real gems hiding in the second week if you're patient. The first few days are a bit of a write-off, honestly. Nothing much happening on the 30th of July, just a weak and messy 3ft swell from the SSE with a light cross-onshore making a mess of things. The combined energy is only 154, so it's flat and weak. The water temp is sittin' at 65°, which is just a touch warmer than normal for this time of year, nothin' to write home about.
Friday the 31st has a clean look in the morning with a cross-offshore breeze, but the swell is tiny at 2ft. The afternoon turns into a lumpy cross-shore disaster with 19 mph winds, so give that a miss. Saturday the 1st of August morning brings a bit more size, 7ft from the NE, but it's a short-period 8-second wind swell. The energy is gettin' up there at 745, but for a beach setup like this, that short period just doesn't stack up for a good wave. It's a clean look, but the quality ain't there for paddle surfing. Sunday the 2nd and Monday the 3rd are more of the same – small, weak, and ordinary.
Now, here's a glimpse of something good if you can wait. The standout of the whole run is Wednesday the 5th of August. We've got a 3ft SSE swell, but the key here is the wind is completely glassy in the morning. The energy is a solid 239, and for a river/jetty break, clean conditions are everything. This is the best bet for a beginner-friendly session, nice and small with no wind.
But the real thumper, the one for the experienced crew, lands on Friday the 7th of August. We're talkin' a 6ft swell from the S, with a period of 11 seconds, pumping a massive 1113 combined energy. That's a lot of water moving. And the kicker? Glassy conditions again in the morning. This is a proper groundswell, and that long period will make for some serious, powerful lines. It's a spot for those who know what they're doin', as that size is definitely for the experts only.
The following week keeps a few decent moments. Monday the 10th of August has a 5ft SSE swell with another glassy morning, energy at 700, a very good session for the more advanced. Then Wednesday the 12th of August gives us a clean 5ft ENE swell in the morning, with a solid energy of 624. That's a good look for a mid-week paddle.
Overall, don't get too excited about the first week. It's mostly small, messy, or wind-affected. The real action is in the first week of August. The 5th is your classic small-wave, glassy fun day, while the 7th is the big one – a powerful, clean groundswell that'll get the heart pumpin'. Keep your eyes on the forecast for that one, as it's still a ways out.
Stay salty,
Rusty
