The Lowdown
Alright, let’s talk about Canto do Leblon. The water is at 74°, which is a touch warmer than what we usually see this time of year – nothing crazy, but nice to know.
The next couple of days are a bit of a write-off with onshore winds and messy conditions. Tuesday 11th sees a 7ft southerly swell, but there’s light rain and an onshore wind, so it’s not going to be clean. The swell energy is pumping hard, but you’ll be battling the wind.
Wednesday 12th is still not great. The morning has a 6ft south swell with cross-shore wind, leaving some ripples on the face. The afternoon gets worse with a stronger cross-onshore breeze and the swell dropping slightly.
Thursday 13th morning is where we first see a real window. A clean 6ft south swell, cross-offshore wind from the north, and moderate wave energy. The south swell with a 13-second period will have some push, and the clean conditions are promising. The afternoon turns onshore again, so morning is the move.
Now, Friday 14th morning is a standout. The wind goes dead calm – glassy conditions – with a 5ft south swell at 13 seconds. The energy is still solid. This is the kind of morning you clear your schedule for. The wind is offshore from the NNW, so expect clean, lined-up waves. The water is still that touch warmer than average, and the consistency is reliable here. The optimum swell direction is from the SE, and we’re getting a pure south swell, so it’s angled well for Canto do Leblon. Crowds are sometimes an issue, but on a Friday morning with a glassy top, it’ll be worth sharing the lineup.
Saturday 15th has a 6ft south swell, but the wind is cross-shore in the morning and gets choppy and strong in the afternoon. Saturday afternoon is a definite no-go.
Sunday 16th drops off to a 3ft south swell. The morning is clean with a cross-offshore breeze, but it’s small. The afternoon gets choppy again.
Monday 17th morning has a small 4ft swell from the ESE with a short 8-second period, but clean conditions. The wind is cross-offshore from the NNE. Not a classic, but if you’re desperate, it’s surfable.
From Tuesday 18th onwards, the surf fades significantly. The swell drops to 3ft or less, and the period stays short. There are a few mornings with glassy conditions, like Saturday 22nd and Tuesday 25th, but the waves are tiny. The combined energy drops way down, so it’s pretty weak.
The best bet by far is Friday 14th morning: glassy, 5ft south swell, solid energy, and clean. Thursday 13th morning is also good. After that, it’s a long stretch of small, weak surf until the end of the forecast period.
