Molhes de Mampituba Surf Forecast and Surf Report

Alright crew, Rusty here breaking down the waves at Molhes de Mampituba for the next couple of weeks.

The best of the lot is right on the doorstep. Thursday morning, September 3rd, is the one to circle. The water temp is 63°, which is about normal for the time of year. We’ve got a clean 5ft swell from the southeast with an 11-second period, and the wind is glassy out of the northwest. That’s about as clean as it gets. The combined energy is a moderate 530, and the forecast is calling for very good surf. The river/jetties break will be working nicely.

Thursday afternoon, the wind shifts to the northeast and goes cross, dropping the swell to 4ft. It’s still surfable, but the window of perfection closes.

Friday the 4th through Sunday the 6th is a dead zone. Onshore wind, small waist-high chop, and short 8-second swell. Not worth the wax.

Sunday the 6th afternoon brings a bigger bump – 7ft from the southwest with a 9-second period and combined energy of 1133 – but it’s cross-shore with a moderate breeze. That’s more of a kite-surfing day than a clean surf session. Monday the 7th morning is glassy with 6ft from the south-southeast, but the short period keeps it from being a standout.

The sleeper pick is Wednesday morning, September 9th. A 6ft swell from the east-northeast, short 7-second period, but the wind is a clean cross-offshore from the north-northeast, and the combined energy is a strong 658. The forecast says “very good surf conditions,” and with that light breeze, it’s going to be a fun morning for the early birds.

After the 9th, the swell sticks around but the wind gets messy. Thursday the 10th afternoon cleans up with a 5ft easterly and offshore wind from the north-northwest – that’s a solid late session. Friday the 11th morning is also clean with a 5ft easterly and light cross-offshore wind.

From the 12th to the 14th, it’s mostly bumpy cross-shore wind and dropping swell. The 14th Monday afternoon shows a spike to 6ft from the east-northeast, but it’s cross-onshore and choppy.

The end of the run, around the 16th and 17th of September, has a couple of glassy mornings. Wednesday the 16th morning has a clean 4ft easterly with cross-offshore wind, and Thursday the 17th morning is glassy with a 3ft SSE swell. Small, clean, and fun on a longboard.

The best session is without a doubt Thursday morning the 3rd of September. Get in the water early. The runner-up is Wednesday morning the 9th of September – bigger swell and clean wind, but short period so don’t expect much grunt. Crowds are often at this spot, so keep your wits about you.

Rusty out.
