The Lowdown
Alright, Rusty here. Let’s take a look at what’s coming for Canto do Leblon over the next couple of weeks. It’s a slow burner, but there are a couple of days that’ll make you glad you didn’t leave your board in the car.
Right off the bat, Monday and Tuesday are pretty much dead. Tiny, weak swells with messy wind. We’re talking waves around 1ft to 2ft, but the energy is next to nothing – combined swell energy is between 34 and 105 (weak). Not worth getting wet.
Wednesday stays poor, with a bit more size from a short-period SSW swell, but it’s choppy and rainy. Energy climbs to 145 (moderate), but it’s still a no-go.
Now, Thursday morning, August 31st, is your first real chance. Clean 4ft groundswell from the SSE with an 11-second period and light cross-offshore winds from the NNE. The water temp is about average for the time of year. Combined swell energy is 407 (moderate), and it’s glassy. That’s the morning to be out there. The afternoon gets onshore and choppy, so make it an early one.
Friday morning, September 1st, is also decent. Swell drops to 3ft from the same SSE direction, still with that nice 11-second period and clean conditions from a light northerly. Energy is 200 (moderate). It’s a smaller version of Thursday, but still clean and fun.
After that, things go flat and messy again through the weekend and into early next week. Rain, onshore winds, and tiny swell. A proper lull.
The next big standout is Tuesday morning, September 8th. This is a bigger, longer-period south swell – 6ft at 12 seconds. Combined energy is 992 (strong). The winds are light and cross-offshore from the NE, keeping it clean. This one has some serious power. For intermediate surfers, it’ll be a ripper. For beginners, 6ft might be a bit much. This is easily the best wave of the whole outlook.
Wednesday morning, September 9th, still has a solid 5ft SSE swell with 11-second period and light cross-shore winds. Energy is 761 (strong). It’s a little bumpy, but still very surfable.
Thursday and Friday, September 10th and 11th, see the swell drop back to the 3ft to 3ft range. Thursday morning has clean conditions with a cross-offshore breeze. Nothing special, but rideable.
The final stretch from September 12th to 15th is mostly small and weak again. Saturday morning, September 12th, has 3ft SE swell with glassy conditions, but the energy is only 248 (moderate) and there’s light rain. Tuesday morning, September 15th, finishes the run with tiny 2ft SE swell and glassy conditions. Just for the longboard or a lazy paddle.
Bottom line: your two best bets are Thursday morning, August 31st for clean, quality groundswell, and Tuesday morning, September 8th for the bigger, more powerful south swell. The rest is mostly small and messy.
