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 July, Arpoador offers decent surf conditions with an average swell height of 1.2m and a solid period of 10.7s, ensuring well-formed and consistent waves. The swell is primarily from the S to SSE, with the most frequent wave heights in the 1-1.5m range (18.23% S) and occasional larger sets up to 2.5m (5.20% S). Smaller, more manageable waves (0.5-1m) are common from the S and SSE, while overhead conditions are rare. Winds are favorable for surfing 51% of the time, with lighter breezes (0-20kph) predominantly from the N to NE, which can help maintain clean conditions. However, stronger winds occasionally come from the E to ESE, potentially causing chop. Overall, July provides good surf opportunities, especially for intermediate to advanced surfers, with the best sessions occurring when winds are light and swells are in the 1-2m range.
