The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming down the line.

First up, the water at Molhes de Mampituba is sitting at 61°, which is a bit colder than what you’d usually expect for this time of year – about 3° off the mark. Not freezing, but you’ll feel it.

The next week and a bit is pretty patchy. There are waves around, but the conditions are often messy. Friday morning (11th) offers a tiny 2ft from the east with a short 8-second period and light cross-off wind – surfable but very ordinary. The energy is weak at 100. That afternoon gets ruined by heavy rain and a strong cross-off. Saturday (12th) sees a bump in size to 6ft from the south, but the period is still short at 7-8 seconds, the wind is cross to cross-on, and the energy is moderate (520-602). It’s choppy and messy – not worth getting wet. Sunday (13th) is smaller at 4ft and still poor.

Monday (14th) hangs around 5ft from the east-southeast with a short period, cross wind, and moderate energy (661). It’s marginal at best. Tuesday morning (15th) is the first real standout. The swell drops to 4ft from the east with an 8-second period, but the wind goes glassy – dead calm. The energy is moderate at 305. That’s clean, small, and fun for a longboard or a fish. Expect good surf conditions. The afternoon turns onshore and messy.

Wednesday (16th) and Thursday morning (17th) are mostly poor, but Thursday morning (17th) is the best of the whole run. Swell hits 5ft from the south-southeast with a long 11-second period and light cross-off wind. The energy is strong at 759. That’s clean, well-shaped, and proper – a true standout for intermediate surfers. The afternoon gets blown out with a 16 mph cross breeze and the swell jumps to 6ft with a very long 13-second period (energy 1301), but the wind spoils it. That’s a setup that might be more interesting for kite surfing than paddling.

Friday morning (18th) still has clean conditions with a 3ft south-southeast swell and 11-second period – very good surf conditions, just smaller. The afternoon and weekend fade back into marginal or poor. Tuesday morning (22nd) offers another glassy window with 5ft from the south-southwest, but a short 7-second period and moderate energy (385). Expect good surf conditions again, but it’s not as special as that Thursday.

Later in the second week, the 25th and 26th have some tiny glassy mornings, but nothing to write home about.

So, the standout here is Thursday, 17th September – morning session at Molhes de Mampituba. That’s the one to circle. Clean, solid groundswell, good energy. Tuesday morning 15th is your backup for a small, glassy session.

Rusty.
