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).

April in Arica offers consistent surf conditions with a dominant swell from the SSW and SW directions, accounting for the majority of wave activity. The average swell height is 1.9m, supported by a strong period of 14.3s, ensuring well-formed, powerful waves ideal for experienced surfers. Waves in the range of 1.5-2.5m are most frequent, making up nearly 50% of the conditions, while larger sets over 2.5m are rare but possible. Wind conditions are less favorable, with ideal surf winds (light and offshore) occurring only 25% of the time. The predominant winds come from the S to SW, often blowing at 10-30kph, which can create onshore chop, especially in the afternoons. Early mornings typically provide cleaner conditions before the wind picks up. Advanced surfers will find the most potential during SSW/SW swells, but should be prepared for variable wind interference. Overall, April delivers solid, powerful waves with periods of good shape, though wind management is key.
