The Lowdown

G'day, Rusty here, lookin' over the next few weeks for the surf around here. The first few days are pretty quiet, but there’s a big pulse of energy coming that'll get the heart pumping. We've got a bit of a slow start, but once it kicks, it'll be on.

Alright, let's start with the first real sniff of a wave. Monday morning, September 8th, at Molhes de Mampituba, the wind is light and cross-offshore from the NNE, so the surface will be clean. We've got a small 4ft swell rolling in from the SSE, with a period of 9 seconds. The combined energy is moderate at 286, so it's not a powerhouse, but it’s a clean, fun little wave for an intermediate. The water temp is sitting at 62°, which is just about average for this time of year, nothing unusual there.

The next real standout comes on Thursday morning, September 10th. Another clean morning at Molhes with a light cross-off breeze from the NNE. The swell drops a bit to 3ft, but the period jumps to a very long 15 seconds. That’s pure groundswell energy, giving you long, waiting sets and proper shape. The combined energy is still moderate at 389, but the quality of the wave will be there. This spot is a river/jetty setup, so those long-period lines will wrap in nicely, better than they would at a straight beach.

Then, hold onto your board. Saturday afternoon, September 12th, is a massive spike. The wind is a moderate cross-shore from the SSW, but the swell jumps to a solid 10ft from the S, with a 10-second period. The combined energy is a huge 4536, which is strong to very strong. This is a big, powerful swell, and it’s forecast to be too big for this break. This is only for experts—if you're a beginner, stay well clear. This is a serious, heavy day.

Sunday morning, September 13th, the swell is still big at 8ft from the SSE, with a 12-second period and a light cross-shore wind from the SW. The energy is still very strong at 1659. This is still a big, expert-only wave. Monday morning, September 14th, the swell is still 7ft from the SE, but the wind is a fresh cross-shore from the NE, making it lumpy. The energy is 1316, still strong, but the conditions are messy.

Looking further out, Wednesday morning, September 16th is a nice little glass-off. The wind is dead calm, zero from the ENE, and the swell is a clean 3ft from the SE with a 12-second period. Combined energy is 374. It’s small, but glassy and perfect for a longboard session.

Friday morning, September 18th is another glassy morning, with a light wind from the NNW. The swell is 3ft from the S with a 12-second period. Energy is 407. That’s a beautiful, clean start to the day.

And finally, Sunday morning, September 20th, we get one more pulse. The swell is back up to 8ft from the ENE, with a 9-second period, and a clean cross-off wind from the NNE. The energy is very strong at 1666, but it's a shorter period swell, so it'll be a bit more lumpy and powerful. Again, for experienced surfers only.

The best of the lot? For quality and cleanliness, I’d pick Thursday morning, September 10th for that long-period groundswell and clean conditions, even if it's small. For the pure adrenaline hit, Saturday afternoon, September 12th is the biggest, but it's a beast. If you’re not an expert, that one is a no-go. The glassy mornings on the 16th and 18th are the real hidden gems for a fun, uncrowded session.

Rusty, signing off.
