Morro dos Conventos - surf spot statistics

Morro dos Conventos in Brazil is a spot predominantly influenced by wind swells, with ground swells playing a secondary role. The best months for surfing here are typically from May to September, when ground swell contribution increases, averaging around 30-40%. During this period, mean swell size peaks at 1.5-1.8 meters, with September offering the largest waves (1.8m). However, wind conditions remain challenging year-round, with good wind days being relatively rare (14-28% probability). The worst wind conditions occur from September to December, when bad wind days exceed 80%. From January to April, swell size is consistent (1.4-1.5m), but wind swells dominate (67-85%), making conditions less ideal for advanced surfers. August and September provide bigger swells but suffer from poor wind alignment, while May and June offer a slightly better balance between swell size and wind conditions (28% good wind days). Overall, intermediate surfers may find manageable waves throughout the year, but the most consistent and powerful conditions occur mid-year despite the frequent onshore winds. For optimal sessions, target May-June when ground swells are stronger and wind odds are marginally better.

March at Morro dos Conventos offers surfable conditions, though with some variability. The average swell height is 1.4m with a solid 9.2s period, indicating consistent, well-formed waves. The dominant swell directions are from the southeast to south (SE to S), contributing the largest share of rideable waves, particularly in the 1-2.5m range. These swells produce clean, organized waves suited for intermediate to advanced surfers. However, wind conditions are a mixed bag—only 26% of the time are winds ideal (likely light offshore or sideshore), while moderate onshore winds from the northeast to east (NNE to E) can occasionally disrupt wave quality. The spot handles larger swells (2m+) well, but consistency drops off in those ranges. For best sessions, target days with SE-S swell and favorable winds, as peak conditions rely on this combo. Overall, March delivers decent surf, though patience and timing are key.
