The Lowdown
Right, gather round. Rusty here, lookin' at the breaks for the next couple of weeks. It's a bit of a slow start for us, but there's a proper pulse of energy building for the second week that's got my attention.
The first decent window doesn't appear until late on the 28th of July. We've got a little bit of activity from the 28th through the 30th, but it's small and pretty ordinary. After that, there's a real dry spell from the 2nd of August right through to the 4th, where the surf is just too weak to get excited about. Things finally start to look up around the 10th and 11th, and that's where the real quality is hiding.
For the standout, I'm looking at Molhes de Mampituba. It's a river/jetty setup, fairly consistent, and it's exposed to the SE swell. The real magic is on Monday the 10th of August. The morning brings a clean, 4ft swell from the south with a very long period of 15 seconds. That's proper groundswell, packing a solid punch of energy (625). The wind is light and offshore, which will have the lines looking glassy. This is a point-break style setup, so that long-period energy will wrap in beautifully. The water is currently 64°, which is about normal for this time of year. It's a solid choice for intermediate surfers.
Then, the absolute highlight of the whole forecast lands on Tuesday the 11th of August. The morning session at Molhes de Mampituba is looking like a dream. We've got a 4ft groundswell from the SSE, with a period of 14 seconds, and the energy is ramping up (876). The wind is glassy, absolutely dead calm. This will be as clean as it gets. The sets will be lined up and powerful. Given the swell direction is right on the money for the optimum (SE), this is the best on offer, no question. The crowd is listed as "often", so expect some company for this one. The following day, the 12th, gets even bigger, pushing 8ft from the ESE, but the period drops to 7 seconds, and the wind turns cross-shore, making it a bit of a messy, powerful wall for experts only.
So, to wrap it up: the first week is a write-off unless you're desperate for a splash. Wait for the 10th, and definitely be on the water on the morning of the 11th for the best of it.
Rusty.
