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.

In January, Rincão typically experiences a moderate swell with an average height of 1.3m and a decent period of 8.3s, making for relatively clean and surfable waves. The majority of swells come from the east to southeast (ENE to SSE), with the best consistency and size in the 1-2m range. The E and ESE directions dominate, offering well-shaped waves, while the SE and SSE swells provide slightly smaller but still rideable conditions. Wind is a key factor here—only 22% of the time is it ideal for surfing, usually when light offshore or cross-shore winds prevail. Unfortunately, northeasterly to easterly winds are common (often 10-30kph), which can create choppier conditions, especially in the afternoons. Surfers should aim for early mornings when winds are lighter and swells are cleaner. Overall, January delivers surfable waves with some good sessions, but wind interference limits the number of perfect days. Advanced surfers can still score quality rides during clean swells, while beginners may find it inconsistent.
