Praia da Rocha - surf spot statistics

Praia da Rocha offers consistent surfing conditions year-round, with the best months for quality waves falling between October and March. During this period, ground swells dominate, averaging 62-88% of the swell activity, providing more powerful and organized waves compared to wind swells. The mean swell size peaks at 1.9m in January, February, and December, making these months particularly favorable for intermediate to advanced surfers seeking larger, cleaner waves. Wind conditions are less ideal, with only 29-35% of days offering favorable offshore or light cross-shore winds—most frequently in September and October. The winter months (November-February) see the highest ground swell consistency, though stronger onshore winds (66-74% bad wind conditions) can occasionally disrupt wave quality. From April to September, swell energy shifts toward wind swells (37-81%), resulting in smaller, less consistent waves (1.0-1.5m). Summer months (June-August) are the least reliable, with weaker swells and frequent onshore winds, though August and September bring slight improvements in wind conditions. For the best balance of swell size, consistency, and manageable winds, target late autumn to early winter (October-December) when ground swells return without reaching their peak winter intensity, and wind conditions marginally improve compared to mid-winter. Advanced surfers may prefer January-February for bigger waves, accepting the higher wind variability.

September at Praia da Rocha offers decent surf conditions with an average swell height of 1.1m and a solid period of 10.5s, providing good energy for clean, rideable waves. The dominant swell directions are NW and WNW, accounting for the majority of waves in the 0.5–2.5m range, ensuring consistent and well-shaped sets. Smaller swells from WSW and SW also contribute, adding variety to the lineup. Wind conditions are favorable 37% of the time, with lighter winds (below 20kph) coming primarily from the NW and WNW, though stronger winds from the N and NNW can occasionally disrupt conditions. While larger swell days (over 2.5m) are rare, the spot handles mid-sized waves well, particularly when the wind cooperates. Expect a mix of playful, rippable shoulders and more powerful peaks, depending on the swell direction. Overall, September is a reliable month for surfers who can adapt to varying wind and swell interactions.
