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.

February at Prainha offers surfable conditions, though not consistently ideal. The average swell height is 1.3m with a decent period of 8.5s, producing somewhat organized waves. The majority of swells arrive from the east-southeast (ESE to SSE), with the most common wave heights ranging between 1-1.5m (peaking at 10.21% from the east). Larger waves (1.5-2.5m) are less frequent but present, mainly from ESE and SSE directions. Wind conditions are a mixed bag—only 24% of the time do they align favorably for surfing. The dominant winds are northeasterly to easterly, often blowing between 10-30kph, which can create choppy or cross-shore conditions. Stronger winds (20-30kph) from NNE and NE are common, potentially disrupting wave quality. Surfers can expect rideable waves, especially when the swell holds in the 1-1.5m range and lighter winds prevail, but consistency and cleanliness vary. It's not a premium month, but patient surfers will find opportunities.
