Molhes de Mampituba Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s talk about what’s on the cards for Molhes de Mampituba. This is a river/jetty setup that’s exposed to the SE, and it’s a fairly consistent spot that can handle a bit of size. The water temp is about average for the time of year, so nothing wild there.

The forecast kicks off with a real punch. Wednesday morning, August 26th, we’ve got a solid 7ft swell from the SSE, with a long 14 second period. That’s a proper groundswell pushing a heap of energy (1758). The wind is a light NNE breeze, keeping it cross-off and clean. This is excellent surf, but at 7ft it’s starting to get serious – this is one for the experienced crew only. The combo of size, long period, and offshore wind makes this the standout of the whole window. The jetty should line this up nicely.

The afternoon on Wednesday gets messy. The wind swings ENE and picks up to 12 mph, putting a cross-chop on that same 7ft swell. The energy is still massive (1928), but the conditions are poor.

Thursday morning, August 27th, drops to 5ft from the SSE with a 13 second period and a moderate NNE wind. It’s clean, but the energy is moderate (1040) and the quality is only marginal. Skip the afternoon – 16 mph NE wind kills it.

Friday morning, August 28th, is another good one. The swell jumps to 8ft from the ENE, but the period is a short 8 seconds. It’s still packing strong energy (1263). The wind is a gentle NNE cross-off, keeping it clean. Again, this is for experienced surfers. The short period means it might be a bit lumpy, but the jetty should help.

Saturday and Sunday, August 29th and 30th, are small but glassy. Mornings have 4ft and 3ft swells from the E with zero wind. The energy is weak (around 200), but the glassy conditions mean you’ll get some fun, clean little waves if you’re patient.

Monday, August 31st, starts with a glassy 4ft SE swell, but it’s short period (7 seconds). It’s surfable, but nothing to write home about.

Tuesday, September 1st, the morning is clean at 5ft from the S, but the afternoon gets ugly. The wind swings to SSW at 16 mph and the swell jumps to 8ft. That’s big, but the cross-chop and wind will make it a mess.

Wednesday, September 2nd, the morning is the next real highlight. A clean 6ft swell from the SSE with a 10 second period, and a gentle WSW cross-off wind. The energy is moderate (568), and the conditions are very good. It’s a great size for intermediates looking for a solid session.

There’s a gap after that until a week later. Thursday, September 10th, closes out the window with a bang. The morning has a 6ft swell from the SSE with a very long 12 second period, pushing strong energy (1192). The wind is a light WSW cross-off, keeping it clean. This is another excellent session for experienced surfers.

In summary, the standout is Wednesday morning, August 26th for the big, clean, long-period groundswell. The next best is Wednesday morning, September 2nd, and then Thursday, September 10th for a late run of quality. Crowds are likely at this spot, so get in early for the standouts.

Rusty.
