Prainha - surf spot statistics

Prainha, Brazil, offers consistent surf year-round, though the best conditions typically occur between May and August. During these months, ground swell makes up a larger portion of the swell mix (38% in May and June, decreasing slightly towards August), leading to cleaner, more organized waves. The mean swell size hovers around 1.5–1.6m, providing solid, rideable waves without being overly heavy. Wind conditions are also more favorable in these months, with May, June, and July seeing the highest percentage of good winds (28%, 28%, and 25%, respectively), reducing the chances of onshore chop. The rest of the year is dominated by wind swell (peaking at 87% in December and January), which can create less predictable and sometimes messier waves. September through December sees a steep drop in favorable wind conditions, with bad winds peaking at 86% in September and October, making these months less reliable. Swell size remains decent in the shoulder seasons, but the increased wind interference lowers overall quality. For surfers seeking the most consistent and clean conditions, the May-to-August window is ideal, offering a balance of ground swell and manageable winds.

June at Prainha offers decent surf conditions with an average swell height of 1.5m and a solid period of 9.8s, indicating consistent and well-formed waves. The swell is predominantly from the southeast to south, with the best wave energy in the 1-2.5m range, peaking in the 1.5-2m category, which is ideal for intermediate to advanced surfers. Wind conditions are favorable for surfing only 28% of the time, with lighter winds from the east to northeast being preferable. However, stronger winds from the north to northwest can create choppy conditions, especially when speeds exceed 20kph. Overall, June provides good surf opportunities, particularly when winds align with the swell direction, though sessions may be limited by less-than-ideal wind patterns.
