The Lowdown
Alright, Rusty here. Let’s break down what Canto do Leblon has cooking for the next couple of weeks.
Right now, it’s pretty quiet. The first few days are flat and forgettable. Saturday the 12th offers a tiny 2ft S swell with 12 seconds, but the cross-off wind makes it rideable though nothing special. The water temp is 73°F – about 2°F warmer than usual, so a touch on the warm side. Sunday the 13th and Monday the 14th are similarly ordinary, though Monday morning does go glassy with a light NNE breeze and a bit of waist-high E swell – surfable but still pretty average.
The real action starts Thursday the 17th. That morning looks great: 5ft of S swell at 8 seconds, glassy conditions, and good energy. The wind stays light and cross-off for the afternoon, keeping it clean. Friday the 18th morning stays solid with 4ft S swell (11-second period) and a clean cross-off NE breeze, but the afternoon gets messy with a strong cross-on ESE wind.
That Thursday-Friday window is the best of the first week – consistent, clean, chest-high waves with good punch.
Then a massive swell hits the end of the forecast. Thursday the 24th sees a jump to 8ft S groundswell with a 14-second period, building to 12ft at 17 seconds in the afternoon. The energy is incredibly strong, but the wind is cross to cross-on and moderate, making it choppy – for experts only. The real standout is Friday the 25th: 10ft S swell with a 16-second period, glassy with a light NE cross-off in the morning, and clean. The energy is insane. This is a bomb for experienced surfers only – not for beginners. The long period will make it hold up well on the point, but could be too straight for the beach.
Saturday the 26th morning is still good at 6ft S swell with 14 seconds and a clean offshore N breeze. After that, it fades back to smaller, cleaner waves for the 27th.
So, the highlights: Thursday the 17th and Friday the 18th for the first week, and the absolute big one is Friday the 25th – a massive, clean, powerful groundswell day. Get ready for that one.
Rusty.
