Rincao - surf spot statistics

Rincón in Brazil is a surf spot that primarily receives wind swells, with ground swells making up a smaller portion of the swell conditions. The best months for surfing at this spot are typically from May to August, when ground swell percentages are higher (ranging from 30% to 39%) and mean swell sizes are more favorable (1.4m to 1.5m). During these months, the wind conditions are also slightly more surfable, with good wind days occurring around 24-29% of the time. September stands out with the largest average swell size (1.7m), but the wind conditions deteriorate, with bad winds present 85% of the time, making it a hit-or-miss month. The early season months (January to April) and late season (October to December) see lower ground swell influence (13-24%) and weaker wind conditions, with bad winds dominating 75-85% of the time. If you're looking for the most consistent conditions, May to July offer the best balance of swell size, ground swell influence, and manageable wind windows. However, surfers should prepare for generally challenging wind conditions year-round, as bad winds prevail in most months. For those prioritizing clean waves, targeting mid-year when wind conditions are slightly better (22-29% good winds) and ground swells are more frequent will yield the best results.

December at Rincão offers consistent surf with an average swell height of 1.4m and a solid period of 8.4s, providing enough power for quality rides. The swell is primarily from the east to southeast, with the highest frequency in the 1-1.5m range, making it ideal for intermediate to advanced surfers. ENE, E, and ESE swells dominate, delivering clean, well-formed waves, while larger swells (1.5-2.5m) occur often enough for more powerful sessions. Wind conditions are a mixed bag, with ideal offshore winds (NE to E) occurring only 19% of the time—when they align, the waves groom perfectly. Unfortunately, onshore winds from the south and southeast are more common, which can chop up the surface, especially at higher speeds (20-30kph). Early mornings or days with lighter winds will provide the best window for clean surf. Overall, December delivers rideable waves frequently, but patience and timing are key to scoring the best conditions.
