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.

June at Leblon offers moderately consistent surf conditions, with an average swell height of 1.2m and a solid period of 11.1s, indicating well-formed and manageable waves. The swell is predominantly southerly (S, SSE, SE), with the highest frequency in the 1-1.5m range (21.3% from S) and occasional bigger sets up to 2.5m+. This creates a mix of playful waist-to-head-high waves, with rare larger days providing more powerful rides. Wind conditions are favorable 53% of the time, typically light to moderate (under 20kph) from N to ENE, which keeps the surface clean. However, stronger ESE or SE winds (occasionally gusting 20-30kph) can bring chop, especially late in the day. Expect the best sessions in the morning before onshore tendencies pick up, with S/SSE swells offering the cleanest shape. While not a big-wave month, June delivers reliable, fun-sized surf for intermediates and above, with occasional punchier days when the S swell peaks.
