Molhes de Mampituba Surf Forecast and Surf Report

G’day, Rusty here. Let’s check out what’s on the cards for our local break at Molhes de Mampituba.

We’re starting off slow on Friday the 10th—pretty flat and messy. Cross-on wind and weak energy (235) mean you’re better off waiting. The water temp is 15°, which is 3° colder than usual for this time of year, so you’ll need a good thick wetsuit.

The first real window opens Saturday morning the 11th. Clean, cross-off breeze from the NNE at 10 mph, and we’ve got a 4ft ESE swell with a 13-second period (groundswell) and moderate energy (554). That’s going to line up nicely at the river mouth—the optimum direction is SE, so the ESE is close enough to push in some decent shape. Saturday morning is the standout early in the period. The waves are on the smaller side, so it’s good for most ability levels, but not cranking.

Sunday the 12th morning gets a bit punchier with a 6ft S swell, but the period drops to 10 seconds and the wind swings cross-shore from the SW at 12 mph, blowing a cross-chop across the break. Combined energy spikes to 1251, but the quality is pretty average—better suited to a kite session than a clean paddle.

Monday the 13th morning is clean again with a light WSW cross-off breeze, and a 6ft S swell, though the period is short at 7 seconds. That’s a windswell, but it’s clean and rideable for intermediates. The energy is moderate (596), so there’s some push but not a lot of grunt.

Tuesday the 14th morning is another good clean window—cross-off NNE breeze at 9 mph, 6ft SE swell with a 10-second period, moderate energy (582). That’s about as good as it gets for the first week: consistent waist-to-chest high waves with clean faces.

Midweek on Wednesday the 15th morning sees a similar setup: 5ft ESE swell, 11-second period, light N breeze at 3 mph making it clean. Nice, but not a standout.

Now, the real standout of the whole outlook comes on Saturday the 18th morning. We’ve got a 6ft NE swell, 8-second period, and a light cross-off NNE breeze at 6 mph. The combined energy is 825—moderate to strong—and the swell direction is ENE, which is a bit off the optimum SE, but the clean conditions and solid size make it the best run of the window. Waist-to-shoulder high, clean, and with that river/jetty setup, it’ll hold shape. There’s a chance of crowds here—it’s listed as “often” busy, so get in early.

Sunday the 19th morning is also solid: 6ft ENE swell, 8-second period, clean again with a light N breeze at 6 mph. Energy is 658—still decent. The morning sessions from Saturday through Monday the 20th are your best bet.

Late in the run, Monday the 21st morning turns glassy with a WSW breeze at 3 mph, and a 5ft S swell with 7-second period. It’s clean but short-period, so not as punchy.

After that, conditions go downhill from Tuesday the 22nd through to the end of the forecast—onshore winds, short-period windswell, and generally choppy or poor surf. The energy drops right off, and the last few days are small and messy.

So, to wrap it up: the best on offer is Saturday the 18th morning—clean, solid 6ft swell, light winds, and the river mouth handling it well. Saturday morning the 11th is a close second for cleaner conditions with smaller waves. The gaps between good sessions are there, but there’s enough to keep you wet if you’re keen.

Rusty.
