Molhes de Mampituba Surf Forecast and Surf Report

G’day, Rusty here, and I’ve been staring at the charts for Molhes de Mampituba. We’ve got a solid 16-day window, but the first couple of days are a bit of a write-off. Saturday the 22nd is a no-go—cross winds and a cross-chop messing up a 7ft south swell. That’s the kind of day you’d rather be on the beach with a cold one.

The real action kicks off on Sunday morning the 23rd. The swell drops back to 6ft from the south, but what makes it special is that light offshore wind from the WSW, cleaning it right up. The period is 12 seconds, so it’s got some proper groundswell energy, and the combined energy is 995 (moderate). It’s a solid pick for intermediates. The water temp is 64°, about average for this time of year, so nothing weird there.

Come Monday the 24th, the swell picks up to 8ft from the SSE, with a 14-second period—that’s a long period groundswell. The energy jumps to 2144 (strong), but the wind is a light cross-shore, which keeps it from being perfect. Still, it’s clean enough for a decent session, especially for experienced surfers who can handle the bigger sets.

The standout of the whole outlook is Wednesday the 26th, morning session. You’ve got a 7ft SSE swell, but the period is a whopping 15 seconds—very long period groundswell. The combined energy is 1663 (strong), and the wind is a light offshore from the NNE. That’s clean, glassy conditions on a river/jetty setup, which is perfect for that kind of long-period energy. This is definitely for experienced surfers only, as the size and power will be demanding. Crowds are often an issue here, so you’ll want to be early.

Thursday the 27th morning is still good, with 4ft SSE swell and 13-second period, and light offshore winds again. The energy drops to 990 (moderate), but it’s clean and fun for a smaller day.

After that, the forecast goes quiet. From Friday the 28th through to the end of the first week, the swell drops way down to around 4ft, and the period is short, 8-9 seconds. The wind shifts around, but it’s mostly cross or onshore. There’s a window on Saturday the 29th afternoon with glassy conditions and a 4ft east swell, 9-second period, but it’s small and weak (225 energy). It’s surfable, but nothing to get excited about.

The second week sees a bit of a pulse come back around Tuesday the 1st of September. The morning has 5ft east-northeast swell with a short 7-second period, but the wind is cross-off and clean. Energy is 410 (moderate). The afternoon improves to 5ft and 8-second period, with a light offshore, and the energy bumps to 540. That’s the best of that week.

Wednesday the 2nd of September morning looks promising—7ft south swell, 8-second period, light offshore winds, and energy of 970 (moderate). It’s a bit short-period, but the clean conditions make it workable. After that, it drops off again into small, weak surf with poor conditions for the rest of the window.

Overall, the best session is Wednesday the 26th of August morning. That’s the one to circle. The Sunday the 23rd morning is a close second. For the rest, it’s a waiting game.

Rusty.
