Arpoador - surf spot statistics

Arpoador, Brazil, offers relatively consistent surf year-round, but the best conditions typically occur from February to August. During these months, ground swell percentages rise significantly, peaking in May (59%) and remaining strong through June and July (59% and 51%, respectively). Ground swells tend to produce cleaner, more organized waves compared to wind swells, which dominate the rest of the year. The mean swell size also increases during this period, averaging 1.1m to 1.3m, providing a good balance of power and rideability. Wind conditions are most favorable from January to June, with the highest likelihood of good winds in February (55%) and a steady decline from July onward. September through November sees the worst wind conditions, with onshore winds becoming more frequent (59-63% bad winds). While summer months (December-January) have smaller swell sizes (0.9m-1.0m) and higher wind swell influence, they still offer surfable waves, particularly when the ground swell component is present. For the most reliable surf with cleaner conditions, mid-year months (May-July) stand out due to the strong ground swell presence and manageable wind probabilities. However, those seeking smaller waves can still find opportunities in the shoulder seasons, though with greater variability in wind quality.

In February, Arpoador offers consistent surf conditions with an average swell height of 1.0m and a solid period of 10.0s, ensuring well-formed waves. The swell direction is predominantly from the south (S, SSE, SE), with the majority of waves in the 0.5-2m range—ideal for intermediate to advanced surfers. Larger sets (1.5-2.5m) occur occasionally, mainly from the S and SSE directions. Wind conditions are favorable 55% of the time, with light to moderate speeds (10-20kph) coming mostly from the NE to ESE quadrants, providing offshore or cross-offshore winds that groom the waves. Strong onshore winds (ESE-SE) are rare but can occur, potentially affecting quality. Overall, February delivers a good mix of rideable waves and clean conditions, making it a reliable month for surfing at Arpoador.
