The Lowdown
Alright, surfers, Rusty here. Let’s talk about what’s cooking at Molhes de Mampituba. The water is sitting at 65°, which is a touch warmer than usual for this time of year.
We’ve got a bit of a slow start, but the first real standout window is shaping up for Saturday, August 15th. That morning, light rain is giving way to a clean 7ft swell from the east with a short, punchy 8-second period. The wind is light and cross-offshore, so the faces should be pretty clean. That energy is sitting at 1183, which is moderate to strong, and it’s got *excellent* conditions written all over it for the experienced crew. Sunday, August 16th morning is also a good follow-up: another clean 7ft wave from the ENE with that same short period, and cross-offshore winds. This is a solid little run for the intermediate to advanced surfer.
Now, later in the week, Monday, August 17th has a bigger pulse – 8ft from the ENE with an 8-second period, and the energy jumps to 1601. That’s a strong push of water, but the wind is light and cross-shore. This one is definitely for experienced surfers only, as it’s in the bigger range.
Looking further ahead, Monday, August 24th is worth keeping an eye on. The morning shows a clean 5ft swell from the SSE with a nice 14-second period. That’s a long-period groundswell, which means good shape and power, and the wind is light and cross-offshore. The energy is moderate at 814. It’s a promising call for the second week, but still a bit of a wait.
Overall, the pick of the entire forecast is Saturday morning, August 15th. Clean conditions, solid size, and good energy. The river/jetty setup here can get a bit tricky with the crowds though – this spot can be often busy, so get there early. The water’s a touch warm, so you won’t need the thickest rubber. Get amongst it.
