Leblon - surf spot statistics

Leblon, Brazil, offers surfable conditions year-round, but the best months for surfers are typically from February to August when ground swell dominates and wind conditions are more favorable. February stands out with a balanced mix of 39% ground swell and 59% wind swell, coupled with 53% good wind days and a mean swell size of 1.0m. March and April see an increase in ground swell contribution (45% and 52%, respectively), with April offering the best swell consistency (no days without swell) and a slightly larger mean size of 1.2m. May through August maintains strong ground swell influence (51-59%), particularly in May and June, where swell size remains around 1.2-1.3m. Wind conditions are most reliable in February and June, with over 50% favorable winds, though August starts to see a decline. September onwards brings a drop in ground swell and a sharp increase in bad wind conditions, making the earlier months preferable. For consistent, clean waves with decent size, target February to June, with April and May being peak months when ground swell peaks and wind interference is manageable. Winter months (June-August) can still deliver good sessions, but autumn (March-May) provides the most balanced combo of swell quality and wind reliability. Avoid September to November, when onshore winds dominate and swell consistency drops.

In October, Leblon offers fairly consistent surf conditions with an average swell height of 1.2m and a decent period of 9.9s, providing surfable and somewhat punchy waves. The swell predominantly comes from the S, SSE, and SE directions, with the most frequent waves in the 1-1.5m range and occasional larger sets up to 2.5m. The wind is onshore (E to SE) 35% of the time, making it ideal for surfing, though it can also blow from other directions at higher speeds, potentially creating choppier conditions. The spot works best when winds are light to moderate (under 20kph) from the E or SE, which helps shape the waves. Expect a mix of smaller, crumbly waves and occasional cleaner peaks, depending on wind and swell direction. Overall, it's a solid month for intermediate surfers, but advanced riders may find it lacking in bigger, more powerful swells.
