The Lowdown
G’day, Rusty here. Let’s break down what’s coming for Molhes de Mampituba over the next sixteen days.
Right off the bat, the first few days are pretty grim. Sunday the 2nd is flat and choppy – no reason to paddle out. Monday the 3rd cleans up a little in the morning with a light cross-off breeze and 3ft swell from the ENE at 8 seconds, but it’s small and nothing special. Tuesday the 4th afternoon turns glassy with a 3ft SSE swell at 11 seconds and no wind – that’s your first half-decent window. Wednesday the 5th through to Saturday the 8th is mostly small and short-period with wind issues. The energy is weak through this stretch (around 100 to 200 units).
Now pay attention to Sunday the 9th morning. Glassy conditions, 5ft S swell at 10 seconds, and combined energy jumps to 539. That’s clean and solid for this river/jetty spot. Crowds are often here, so get there early.
The biggest standout is Monday the 10th morning. Glassy, 7ft S swell at 12 seconds, combined energy at 1209 – strong, long-period groundswell. This is expert territory only. The long period will make the waves powerful and well-shaped at this jetty. The wind is out of the W, offshore for this break. Don’t waste the afternoon; it goes cross-onshore and messy.
Tuesday the 11th morning stays clean with 5ft S swell at 12 seconds and a cross-off breeze. Wednesday the 12th morning is glassy again with 5ft SSE swell at 12 seconds – still really good. Then a few poor days from the 13th to the 14th with onshore wind.
Saturday the 15th morning returns with a clean 6ft ESE swell at 8 seconds and cross-off wind (energy 517). Short period so peaky but rideable. Sunday the 16th morning is the last big moment: glassy, 8ft ENE swell at 8 seconds, energy at 1350 – huge and dangerous for experts only. Afternoons get torn up by strong wind.
Water temps are standard for this time of year.
Your best bets are the mornings of the 10th and the 16th. Go get it.
