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).

In September, Arica offers consistent surf conditions with an average swell height of 1.9m and a solid period of 13.9s, indicating powerful, well-spaced waves. The majority of the swell comes from the SW and SSW directions, with the most frequent wave heights falling between 1.5-2.5m, providing ideal conditions for experienced surfers looking for powerful, barreling waves. Wind conditions are favorable for surfing only 17% of the time, with the most common winds blowing from the SSW and SW directions at moderate speeds (10-30kph). While onshore ESE and SE winds can occasionally disrupt conditions, mornings often see lighter winds, making them the best time to score clean sessions. Overall, September delivers high-quality waves for advanced surfers, though wind variability requires careful timing.
