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.

June at Morro dos Conventos offers consistent surf with an average swell height of 1.5m and a solid 10s period, providing decent power and shape. The dominant swell directions are S, SSE, and SE, with the highest frequency of waves in the 1-2.5m range—ideal for intermediate to advanced surfers. The best conditions come from southerly swells (S to SE), which produce the most rideable waves, especially in the 1.5-2.5m range. Wind conditions are somewhat mixed, with only 28% of days offering ideal offshore (NW to NE) or light cross-shore winds. The main challenge is onshore winds from the N to SSW, which are frequent and can degrade wave quality, particularly when stronger than 20kph. Overall, June delivers reliable surf, but wind management is key—aim for early sessions or days with lighter NNE to ENE winds for cleaner conditions.
