The Lowdown
Second text (Imperial)
Alright, let’s look at this in feet and miles per hour. It’s been a slow start, but don’t walk away – the goods are coming.
The first few days are flat. Not worth the wax. But we get a taste on Friday the 7th of August. A clean 2ft wave from the ENE with a cross-off breeze at Molhes de Mampituba. The water is 66°F, a touch warmer than usual for this time of year.
The real standout is Saturday the 8th. Molhes de Mampituba is the spot. Saturday morning we’ve got a solid 6ft SSE swell (12-second period) with a clean cross-off wind. The wave energy is moderate at 1119. Saturday afternoon cleans up even more with a 5ft SSE swell and light cross-off winds. It’s gonna be very good.
Sunday the 9th holds similar size, 6ft from the S, but the wind turns a bit cross. It’s still fun, but Saturday is the one to chase.
Into the second week, Thursday the 13th brings a 6ft SSE swell with a long 14-second period. That’s a proper groundswell, and it’ll work well at the river/jetties. It’s a bit onshore, but the energy is strong (1610). For the experienced crew, the big one is Saturday the 15th. Molhes de Mampituba sees a 8ft ENE swell (8-second period) with a clean cross-off wind and excellent conditions. That’s big – over 8ft is only for experts, so 8ft is still expert territory. It’s short period, so it’ll be a bit sectiony, but the power is serious (1146 combined energy). Sunday the 16th morning is still good with a 7ft ENE swell and clean cross-off.
After that, there’s a gap of poor conditions from the 16th afternoon through the 17th. But Tuesday the 18th morning brings another clean 7ft S swell with cross-off winds. That’s a solid one for the experienced. Wednesday the 19th morning is also excellent, with a 6ft SSE swell and clean conditions.
The standout is Saturday the 8th for the cleanest, most user-friendly surf. For the big wave hunters, Saturday the 15th is the one to circle. The river/jetties setup handles the long period swells well, but the short-period stuff can be a bit sectiony. Watch the wind, and you’ll score.
