The Lowdown
Alright, listen up. Rusty here, talking about Canto do Leblon. The first week is mostly a washout – small, weak, and all chopped up. You're gonna wait almost a week for anything that actually looks like a wave.
Sunday, August 30th? Forget it. Tiny 0.7m to 0.5m from the ESE with a short 8-second period and a cross-shore breeze messing it up. The energy is weak. Monday, August 31st is glassy but flat – 0.4m is just a ripple. Tuesday, September 1st has a glassy afternoon, but the wave is still only 0.6m. Not worth paddling out.
Wednesday, September 2nd gets some size – 1.8m from the SW – but it’s got a terrible 6-second period and a strong cross-onshore wind. That’s a blown-out mess, with 374 energy. Hard pass. Thursday, September 3rd brings the first clean moment: 1.2m from the SSE, 8-second period, clean cross-off wind in the morning. Energy is moderate (317), and it says “expect good surf conditions.” That’s a go. Friday, September 4th is the same story in the morning – 1.2m, 10-second period, clean.
The real standout, the one you circle on your calendar, is Monday, September 8th. The morning is an absolute bomb: 3.0m of south groundswell with a 16-second period – that’s a very long period, deep water energy. The combined energy is massive (4536), and you’ve got a light cross-off breeze. It says “excellent surf conditions for experienced surfers.” That is a lot of water moving. Over 2.5m, so experts only. The point break setup should handle that long period well, but the sets will be wide and powerful. Tuesday, September 9th is still strong – 1.6m, 13 seconds, glassy in the morning. Moderate energy (984), but super clean.
The second week stays fun. Thursday, September 11th has a clean 1.0m with a gentle offshore. Saturday, September 13th brings a glassy 2.3m from the SE, and Monday, September 14th closes with a glassy 1.8m. The water temp is about average for the area, nothing strange. So, bottom line: if you want the trip of the forecast, you wait for that Monday, September 8th sunrise. Everything else is a warm-up.
Rusty.
