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.

March at Leblon offers decent surfing conditions with a mix of manageable swells and generally favorable winds. The average swell height is around 1.1m, with a solid period of 10.4s, indicating well-spaced, organized waves. The swell is primarily from the south (S, SSE, and SE directions), contributing to the majority of rideable waves, particularly in the 0.5-1.5m range. Larger swells (1.5-2.5m) are less frequent but provide occasional punchier sets. Wind conditions are favorable 50% of the time, with lighter breezes (0-20kph) from the ENE through ESE directions, minimizing chop and keeping the surface clean. Stronger winds (20-30kph) from the ESE can occasionally interfere, but overall, March delivers consistent, surfable conditions with a mix of smaller, user-friendly waves and occasional bigger, more powerful sets for those seeking a challenge.
