Molhes de Mampituba Surf Forecast and Surf Report

Alright, Rusty here. Let's look at what's on the table for the local stretch.

We're looking at a solid 16-day window starting now, but there's no surf worth paddling for right at the start. The first real chance we get is on the 27th of August, but honestly, it's a bit of a tease. We are focusing on Molhes de Mampituba, a river/jetty setup that's exposed to the swell.

The water's sitting at 60° which feels a bit colder than normal for this time of year, so you'll want that extra mil.

Thursday the 27th is a light day. In the morning it's a no-go. We get a little push in the afternoon with 4ft from the SSE (13 seconds) but the wind is a cross-shore from the NE at 12 mph, kicking up a bit of a cross-chop. The energy is moderate (596). It's not the best, but you might find a sneaky one.

Friday the 28th has a morning session with 6ft from the ENE. The period is short, only 8 seconds, and a light cross-shore NE wind. The energy is moderate (766). It’s surfable but messy. The afternoon turns ugly with a cross-onshore wind, so forget it.

Now, Saturday the 29th is where it starts to get interesting. Saturday morning is looking glassy. The wind is a whisper from the NNE at 3 mph, making the surface clean. Swell is 4ft from the ENE (8 seconds) with moderate energy (205). It's not big, but those clean conditions will make it fun. The afternoon goes downhill.

Sunday the 30th morning is another glassy session with weak 3ft waves (163 energy). It's surfable but ordinary. The afternoon gets heavy rain and a cross-on wind, so don't bother.

The next few days are a mixed bag of onshore winds and marginal conditions. Then we hit a standout.

Monday the 31st afternoon is something special. The wind drops to glassy conditions, and we get a push of 7ft from the ENE at 8 seconds. The energy is strong (931). This is the pick of the first week. It's a bit big for beginners, but for the intermediates, that's some serious fun on offer at the jetties.

Tuesday is a mess with strong winds, but then Wednesday the 2nd of September morning comes in clean. Glassy offshore wind from the WSW, 6ft from the SSE with a 10-second period, and good energy (684). That's a proper morning session.

The following days shrink down to small waves (2ft - 4ft) with clean winds early on the 4th, 5th, and 6th of September. These are small-wave days, good for a longboard or a log.

The pattern gets messy again for a week, but then Thursday the 10th of September afternoon offers up a real chance. We have a clean, cross-offshore wind from the west, bringing in 5ft from the SE (9 seconds) with strong energy (749). That looks like the best call for the second week.

On the 11th, the swell stays up around 6ft to 7ft, but the wind is either cross or onshore, making it a bit lumpy. The energy is still strong (864 and 755), but the conditions won't be as clean as the 10th.

The standout of the whole run is Monday the 31st of August afternoon for the clean, glassy 7ft swell, and Thursday the 10th of September afternoon for the clean, surfable 5ft. For small-wave fun, the mornings of the 29th and 30th of August are your glassy windows. The jetty will handle the size, but keep an eye on the tide.

Rusty, signing off.
