Molhes de Mampituba Surf Forecast and Surf Report

Alright folks, Rusty here. Let's get into it. We've got a decent little run shaping up at Molhes de Mampituba over the next couple of weeks, but you gotta pick your moments. The water's sitting at a nippy 59°, which is about 5° colder than it should be for this time of year – that's a proper cold snap, so you’ll want the thickest winter rubber you've got.

The forecast kicks off today, Tuesday the 7th, with a clean morning. We’re looking at a 4ft SSW swell with a short 7-second period, but the wind is light and cross-off from the west, so it'll be workable. The real gem of the morning is the glass-off in the afternoon – a 4ft swell from the SSW with absolutely no wind. That’s clean, that’s smooth, that’s your session. The combined swell energy is moderate at 274.

Wednesday the 8th morning keeps it tidy, with a lighter 3ft S swell that has a nice 11-second groundswell period. Offshore winds from the NNW will have those waves standing up well on the river jetties. It's a clean, fun-sized option before the wind swings onshore in the arvo.

We hit a bit of a lull through Thursday and Friday the 9th and 10th – small, short-period stuff and tricky winds. Not worth paddling out for unless you're desperate for a float.

Now, here’s the standout. Saturday the 11th morning is the one to circle. We get a 4ft ESE swell with a pumping 13-second period, delivering a very strong combined swell energy of 524. The wind is light and cross-off from the NNE, which should groom those jetties perfectly. These are the kind of conditions that make you call in sick. Expect very good surf.

Sunday the 12th morning keeps the fun going with a bigger 6ft SSE swell and an 11-second period. That’s getting up there size-wise, maybe a bit too much for the beginners, but for the experienced crew it’s game on. The wind is almost nothing from the north, so it'll be clean with some serious push. Energy is strong at 937.

After that, the wheels come off a bit. Monday the 13th gets smashed by strong SW winds at 19 mph, making a mess of the 3ft swell. That’s kite-surfing weather, not paddle surfing. The following week is a mixed bag of small, short-period ENE swells with mostly cross or onshore winds. Morning windows on the 16th and 17th show some clean, cross-off conditions on small 3ft to 4ft waves, but the period is a short 7 seconds so it’ll be a bit weak and crumbly. A couple of arvo sessions later in the week are blown out by 16 mph winds.

So, to sum it up: your best bets are this afternoon (Tuesday 7th) for the glassy perfection, and Saturday the 11th morning for the best quality swell of the entire 16-day window.

Rusty.
