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 August, Leblon offers surfable conditions with an average swell height of 1.3m and a solid period of 10.7s, indicating well-formed, consistent waves. The swell direction is predominantly from the south (S to SSE), contributing to the majority of rideable waves, with the best energy coming in the 1-2.5m range. Smaller waves (0.5-1.5m) are frequent but less powerful, while larger sets (over 2.5m) are rare. Wind conditions are favorable for surfing 46% of the time, typically light to moderate (10-20kph) and often blowing from the NE to E, which can be offshore or cross-shore depending on the exact angle. However, stronger winds (20-30kph+) from the E to SE occur occasionally and may create choppier conditions. Overall, August provides decent surf opportunities with a mix of manageable waves and workable winds, though consistency depends on picking the right sessions when wind and swell align.
