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.

October at Arpoador offers decent surf conditions with an average swell height of 1.2m and a solid period of 9.9s, ensuring well-formed waves. Swell primarily arrives from the south (SSE to S), contributing to the majority of rideable waves, with the best size range (1-2.5m) peaking in consistency from the S direction. Smaller swells from the SE and ESE add variety but are less dominant. Wind conditions are favorable 37% of the time, with the biggest issues coming from ENE to E winds, which can blow onshore at moderate speeds (10-30kph). However, lighter winds from the SSW to W sectors occasionally clean things up. Overall, October provides consistent, mid-sized waves with enough good wind days to make it worthwhile, though surfers should watch for stronger easterlies that can disrupt conditions. Solid for intermediate to advanced surfers when the wind cooperates.
