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.

In May, Morro dos Conventos offers decent surf conditions with an average swell height of 1.6m and a solid 10-second period, indicating well-spaced, powerful waves. The dominant swell directions are from the south (SSE, S, and SE), accounting for most of the rideable waves, with heights frequently in the 1-2.5m range. This setup suggests consistent, clean lines with good energy, ideal for intermediate to advanced surfers. However, wind conditions are less favorable, with ideal offshore or light cross-shore winds occurring only 28% of the time. The predominant winds come from the N, NNE, and NE, often blowing at 10-20kph, which can create choppy or onshore conditions. While there are plenty of surfable days, the best sessions will depend on wind alignment—early mornings or specific wind shifts may provide cleaner waves. Overall, May delivers reliable swell but requires patience for optimal wind conditions.
