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 June, Arpoador offers surfers a mix of favorable and manageable conditions. The average swell height is 1.2m with a solid 11.1s period, indicating well-spaced, clean waves. Most swells come from the S and SSE directions (48.87% of waves between 1-2.5m), providing consistent, rideable energy. Smaller swells (0.5-1.5m) from the SE and ESE add variety, while larger sets (2-2.5m) are less frequent but present. Wind conditions are surfable 54% of the time, with lighter NNE to E winds (10-20kph) dominating early in the month, though occasional stronger ESE winds (20-30kph) can create choppier sections. Offshore winds (WNW to NNW) are rare but occur, offering brief glassy windows. Overall, June delivers dependable waist-to-head-high waves with good shape, best suited for intermediate to advanced surfers who can navigate the occasional wind-affected sections. Mid-morning sessions often provide the cleanest conditions before afternoon breezes pick up.
