Molhes de Mampituba Surf Forecast and Surf Report

Alright folks, Rusty here. Let's look at whats on the menu for Molhes de Mampituba over the next couple of weeks. Theres a bit of a slow start to get through, but theres some promising windows coming our way for this river/jetty setup.

The Overview

Alright, theres no surf on offer right this second but come Wednesday morning, September 2, theres a little pulse showing up. So a short wait. Overall, the river mouth itself is *fairly consistent* for the area, looking at that SE swell direction that she loves. The first week is a mixed bag of good and forgettable, but the second half of the forecast has some real potential, even if its a bit further out.

Wednesday, September 2 – A Clean Window

The standout for the start of the period is Wednesday the 2nd. Early, the wind's glassy out of the W at 3 mph, making it feel like a morning session you dream about. We've got a solid 5.9ft of SE swell, with a period of 10 seconds producing moderate wave energy (573). The water temp is 63.1°, which feels about average for this time of year, nothing weird going on there. This is the call for the early birds – expect very good surf.

Later that day the wind swings E and goes cross-on at 6 mph. Conditions will get a little bumpy, so the clean morning is the window. This swell means its fine for intermediate skill levels.

Thursday, September 3 – A Smaller Clean Repeat

Thursday the 3rd also has a glassy morning with NW winds at 3 mph, bringing a little smaller 4.6ft of swell from the SE. The period stretches to 11 seconds, a little longer and more lined up. The energy is moderate (472). Conditions will be clean and fun again, but the swell is down a notch. Afternoon goes side-on again with light ENE, so its back to the morning for the best of it.

Friday, September 4 to Sunday, September 6 – A Poor Run

Theres a blanket of poor conditions from Friday. Swell drops right off to under 3 feet, and the wind is cross-on or cross-shore from the S and SW, blowing 9 to 15 mph through the weekend. Energy figures get low (105 to 343). Nothing surfable worth paddling for here guys.

Monday, September 7 – Still Uninspiring

Monday sees the swell pick back up to 5.2ft from the SSE with 9 seconds and moderate energy (382 to 463), but the wind is still messy from the S and SW. The morning has a cross-shore chop and the afternoon is cross-on. Marginal at best.

Tuesday, September 8 – A Clean-ish Return

Tuesday the 8th shows some relief. On the morning, we get a light cross-offshore breeze from the NNE at 6 mph. The swell is a smaller 3.9ft from the SSE at 10 seconds with moderate energy (336). It's clean, but not pumping. A solid little session if you are keen for a paddle.

Wednesday, September 9 – A Solid Pulse

Now this is where it gets interesting. On Wednesday morning the 9th, theres a jump in swell size to 6.9ft from the NE, with a short period of 8 seconds. The wind is cross-offshore out of the NNE at 9 mph. The energy is moderate to strong (798) and the report is expecting very good surf. This size is pushing into bigger territory, maybe a bit much for beginners, but for the intermediates and up, with clean conditions, this is a ripper morning. The afternoon blows up with 18 mph cross-shore winds, so the window is tight on the morning.

Thursday, September 10 – Another Glassy Window

After a choppy and rainy morning Thursday, the afternoon of the 10th glass's off again with NW winds at 3 mph. We got a 5.2ft swell from the E at 9 seconds and moderate energy (460). Good surf expected in the glass, but again the morning is a write-off.

Friday, September 11 to Sunday, September 13 – Mixed Bag

The middle of the week looks inconsistent. Some marginal conditions on Friday with light cross-onshore winds. A clean and glassy morning on Saturday the 12th with a 3.6ft E swell, but its short. Sunday gets blown out again.

Monday, September 14 – Another Star in the Forecast

Now this is the long-range standout. Monday the 14th is shaping up to be a beauty. Early on, we have glassy conditions with a light SW wind at 3 mph. The swell picks up to 5.2ft from the ENE with a short period of 8 seconds. The combined energy is strong (790). This is a classic river/jetty setup with a clean face. This is the one to circle on the calendar, but keep in mind its over a week away.
