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.

October at Morro dos Conventos offers decent surf conditions with a mix of rideable waves, though wind interference can be a limiting factor. The average swell height is 1.6m with an 8.9s period, providing consistent, moderately powerful waves. The majority of swell comes from the E/ENE/SE quadrants, with the cleanest waves typically arriving from the ENE to SSE range, where 1.5–2.5m waves are most frequent (peaking around 8–12% distribution per direction). While smaller waves (0.5–1.5m) are common, overhead+ conditions (over 2.5m) are rare, occurring less than 1% of the time. Wind is the main challenge—only 14% of the time is it ideal (likely light/variable or offshore). The most problematic winds are NNE to NE (10–30+ kph), which are onshore and occur over 15% of the time, potentially creating chop. SSW winds can also be disruptive. Surfers should target early mornings or days with wind shifts to ESE/SE for cleaner conditions. Overall, October delivers workable waves, but patience and timing are key to scoring the best sessions.
