Canto do Leblon Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Canto do Leblon over the next couple of weeks. It’s a bit of a mixed bag, but there are a couple of sessions that will get the heart racing if you time it right.

The water here is sitting at a balmy 73°, which is a touch warmer than normal for this time of year – nice for a long session without needing a thick wetsuit.

The forecast starts off pretty tame. Thursday the 20th is a write-off with tiny, weak swell and a cross-onshore breeze. Friday the 21st morning shows a slight improvement with clean conditions and a light offshore wind from the NNW, but the swell is still small at 2ft. Friday afternoon goes downhill fast with a strong cross-shore wind messing things up. Saturday the 22nd and Sunday the 23rd see a bit more size, but the wind is never your friend, so the surf is poor to marginal. Monday the 24th brings some serious size – 6ft to 8ft – but with light rain and a persistent cross-onshore wind, it’s choppy and messy.

Now, here’s where it gets interesting. Tuesday morning, the 25th of August, is a standout. We’ve got a solid 7ft of south swell, with a long period of 14 seconds – that’s proper groundswell. The wind is light and cross-offshore from the NE, keeping the waves clean. The combined energy is pumping at 2029 (moderate-strong energy), and it’s marked as excellent conditions for experienced surfers. This is not for beginners; at over 8ft, it’s expert territory. Canto do Leblon is a beach and point setup, and a long-period south swell like this will favor the point section for better-shaped, longer rides.

Wednesday morning, the 26th, is another gem. The swell drops slightly to 6ft, but the wind goes completely glassy from the NNE – dead calm. The energy is still strong at 1307, and the 14-second period means quality waves. This is a fantastic window for a clean session, still very good for experienced surfers but a touch more manageable.

Things taper off after that. Thursday the 27th morning still has good, clean 5ft surf, but by the afternoon the wind swings onshore and chops it up. Friday the 28th morning offers a clean 3ft, but it’s small. The rest of the month and into September looks small and mostly messy, with only brief clean moments. There’s a gap of several days with no real recommendations after the 28th morning.

Then, looking way ahead to Thursday morning, the 3rd of September, the models hint at another big pulse. A whopping 7ft of south swell with an incredibly long 17-second period and light cross-offshore winds. The combined energy is massive at 2424, pointing to strong wave energy. This is a promising long-range prospect, but it’s two weeks out, so keep an eye on it. Again, this is expert-only size and power, and with that period, the point at Leblon will be the spot to handle it.

So, the two true standouts are Tuesday morning the 25th and Wednesday morning the 26th. For the rest, it’s mostly about waiting for a clean window on a smaller day, like Friday morning the 28th if you’re desperate for a paddle.

Stay stoked,
Rusty
