Molhes de Mampituba Surf Forecast and Surf Report

G'day, it's Rusty here. We've got a solid 16-day window on the cards at Molhes de Mampituba, a river/jetty setup that's fairly consistent. It's mostly gonna be a story of waiting for the right windows, but when it lines up, it's a treat. The water temp is sitting at 63°, which is about average for this time of year, nothing to write home about there.

The action kicks off on Thursday, the 3rd of September. The morning is the standout early call. We've got a clean 5ft swell from the SE, with a long 11-second period, meaning groundswell energy is in the water. The wind is a glassy 3 mph from the NW, making it absolutely perfect conditions. The combined energy of all swells directed here is a moderate 474, and the waves are set to be good. This is your best early bet. The afternoon, however, gets messy with a cross-shore breeze and smaller swell, so stick to the morning.

Friday the 4th through Sunday the 6th is a write-off. The wind turns onshore, the swell drops, and conditions are poor. It's a bit of a bleak stretch, so give it a miss.

Now, Monday the 7th is a beauty. The morning brings a clean 6ft swell from the SSE, with a moderate period of 9 seconds. The wind is glassy again from the ENE, at only 3 mph. The combined energy is a moderate 535, and the forecast is for very good surf. This is another top-shelf session. The afternoon holds up okay too, with clean waves from a cross-offshore breeze, but the morning is where it's at.

Tuesday the 8th starts clean with a 3ft swell from the SSE, but the wind picks up strong in the afternoon, ruining the session. Wednesday the 9th, the morning is a ripper. We see a 6ft swell from the ENE, with a clean cross-offshore breeze. The combined energy is a moderate 697, and the call is for very good surf. That's a solid morning session.

From Thursday the 10th to Saturday the 12th, it's a mixed bag of mediocre conditions. The swell is around, but the wind is messy or onshore, leaving the waves ordinary at best. Nothing to get excited about.

Sunday the 13th gets interesting. The morning brings a 8ft swell from the S, with a combined energy of 1658, which is strong. The wind is light and cross-shore, but the period is only 9 seconds. This is getting big for beginners, and with the cross-shore wind, it'll be a bit lumpy. It's a marginal call, but the energy is there. Monday the 14th morning is the absolute standout of the whole forecast. We have a 6ft swell from the SSW, with a clean cross-offshore breeze from the N. The combined energy is a strong 1107, and the call is for excellent surf conditions for experienced surfers. This is the one to circle on your calendar. The afternoon goes to shit with a strong cross-shore, but that morning is gold.

The week of the 15th to the 18th has waves on offer, but the conditions are a bit more fickle. Tuesday the 15th morning is clean and glassy with a 4ft swell, a good session. Wednesday the 16th morning is also clean with a 3ft swell. The long-range stuff from the 17th and 18th is promising but less certain. The 17th and 18th see some big, long-period groundswell from the SSE (15-17 seconds), but the wind is mostly onshore or strong, making it lumpy. The 18th of September has a 6ft swell from the SSE with a very long 15-second period, but a cross-shore wind will have it chopped up. That's one for the experts to watch, but don't get your hopes up too high.

Overall, the best on offer is the morning of the 14th of September for experienced surfers, and the mornings of the 7th and 9th of September for cleaner, more manageable waves. The crowds here are often, so expect some company on the good days.

Rusty.
