The Lowdown
Alright folks, let’s talk waves for Canto do Leblon. I’ve been digging through the data and it’s a bit of a patchy period, but there are definitely a couple of days you won’t want to miss.
The water is running about 73° right now, which is a touch warmer than usual for this time of year, so that’s a little treat. Right now, we’ve got some moderate energy in the water – around 223 – but the surf itself is pretty underwhelming. We’re looking at about 3ft of south swell, but it’s just not doing much.
Wednesday is pretty flat and uninspiring. The morning has a glassy surface, but there’s barely a wave to get excited about. The afternoon brings rain and an onshore breeze, making for poor conditions.
Thursday looks a little better. The morning brings a light cross-off wind, and the energy picks up to 290. The swell is still around 3ft, but the period stretches out to 12 seconds. It’s clean and has a bit more push. The afternoon keeps that quality – 3ft waves, period up to 13 seconds, and energy climbs to 305. It’s not big, but it’s clean and fun. A decent way to get the stoke back.
But Friday morning, that’s the one. The wind is dead calm – absolutely glass. The swell builds to 4ft and the period just jumps to 14 seconds. This is proper groundswell, with some real energy behind it – the meter reads 525. That’s the biggest jump we’ve seen. These waves are going to be well-shaped with some punch. The point should be handling it perfectly. Cancel your plans. This is the session. Friday afternoon, the easterly wind picks up and turns it into a chop-fest, so it’s strictly a morning surf.
Saturday is a bit of a letdown. The swell drops, the energy plummets to 121, and we’re back to ordinary conditions. Sunday brings some size for sure – we’re talking 4ft in the morning building to 6ft in the afternoon with energy climbing to 727 – but the wind is all wrong. It’s cross-onshore and bumpy. That’s not surf for us; that’s a kiteboarding kind of day.
So we have a couple of dud days, but Monday the 14th, that’s the next big one. The wind swings to a nice cross-off. The morning serves up 6ft of southeasterly groundswell with a solid 10-second period. Energy is pumping at 774. The notes say it all – “very good surf conditions.” The afternoon, it gets even better. We’re looking at a solid 6ft, energy jumps to a massive 846, with an 8-second period. It’s powerful, it’s got size. It’s pushing toward that expert territory, so have your wits about you, but for those who can handle it, this is a day to remember.
Tuesday morning, the 15th, gives you a break – 5ft of cleaner, cross-off swell with energy at 425. Still decent. But the afternoon turns poor again with a cross-onshore breeze chopping it all up.
Looking further out, things get a bit unpredictable. The 16th and 17th show some swell – one reading has 5ft with a 13-second period – but the winds are all over the place, making for iffy conditions.
So there you have it. The two days to really clear your schedule for are Friday morning the 11th and Monday the 14th. They are the pick of the bunch by a long way. The rest is a waiting game.
