Arica - surf spot statistics

Arica, Chile, is a world-class surf destination known for its consistent ground swells and powerful waves, offering excellent conditions throughout the year. The swell is almost exclusively ground swell (94–99% of the time), with minimal wind swell interference, making it a reliable spot for clean, well-formed waves. The average swell size increases from 1.5m in January to a peak of 2.0m from June to August, then gradually decreases toward the end of the year. However, wind conditions are a key factor—the best months for surfing in Arica are those with higher percentages of favorable winds. February stands out with the least onshore wind interference (36% good wind conditions), followed by January and March (31–33%). From April onward, the likelihood of bad winds increases significantly, dropping to only 16–25% favorable wind days, which can make the surf choppy and less ideal despite the solid swell size. For advanced surfers seeking the biggest waves, June through August deliver the largest swell (2.0m), but the strong onshore winds (78–84% bad conditions) make these months more challenging. For a balance of solid swell and relatively better wind conditions, target January to March, when the swell is still strong (1.5–1.7m) and winds are less disruptive. December also offers slightly improved winds (21%) compared to the mid-year months, though with marginally smaller waves. Overall, if you prioritize clean, rideable waves, the early months of the year (January–March) are optimal, while those hunting bigger, more powerful waves—and willing to take on gustier winds—should aim for the southern winter (June–August).

June in Arica offers consistent surf conditions with a dominant swell from the SW and SSW, producing an average swell height of 2.0m and a strong period of 14.2s—ideal for powerful, well-formed waves. The majority of waves fall in the 1.5-2.5m range (50-60% of the time), ensuring solid, rideable surf, while larger sets over 2.5m occur occasionally. Wind is the main variable: only 22% of days have favorable offshore or light conditions (typically from the east), while the rest see onshore SSW/SW winds at 10-30kph, which can create chop. Windier sessions may still be manageable due to the swell’s power, but the best days will be those with lighter E/ESE flow. Overall, expect reliable waves for experienced surfers, with peak conditions when wind cooperates.
