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 May, Leblon offers decent surf conditions with an average swell height of 1.3m and a solid period of 11.0s, ensuring well-formed, consistent waves. The swell distribution shows that the majority of waves come from the southern quadrant, with the highest frequency in the S and SSE directions—ideal for this beach. Waves in the 1-2m range are common, providing good surf for intermediate to advanced surfers, while larger sets (2-2.5m) occur around 5% of the time, adding occasional power for those seeking more challenge. Wind conditions are favorable 50% of the time, predominantly light to moderate from the NE to E, which is offshore or sideshore, enhancing wave shape. However, ENE-E winds can occasionally get stronger, potentially creating choppiness. Overall, May delivers reliable surf with clean conditions half the time, making it a worthwhile month for surfers who time their sessions with the right wind.
