Arica - surf spot statistics

Best Surf Season (May - August)

While Arica's exposure to the deep South Pacific guarantees a steady supply of long-period swell, the persistent onshore wind regime keeps quality at a premium. The austral winter months (May through August) see the highest average swell heights (1.8m) and longest periods (up to 13.7s), delivering the most powerful waves of the year. Though the dominant swell direction remains SSW and SW—far from ideal for the WNW-facing beach—the sheer energy can occasionally overcome the constant WSW and W winds, offering more size and punch for the dedicated surfer. This is the window to chase if you are willing to work with wind-affected, yet more substantial, surf.

Fair Surf Season (September - November & March - April)

The shoulder seasons bring a slight drop in average swell height (1.6-1.7m) while periods stay solidly in the 13s. The wind pattern shows little change, with onshore flows from the WSW and W dominating over 90% of the time. However, these transitional months can see a slightly higher frequency of lighter morning wind events before the afternoon onshore breeze kicks in. Combined with the consistent long-period swell, these windows provide the best chance for the most rideable, albeit still angled, waves. Patience and an early alarm are key.

Low Surf Season (December - February)

The austral summer delivers the smallest average swell heights (1.5m) and the shortest periods (around 12.6s). Swell continues to come from the sub-optimal SSW and SW directions, and the wind relentlessly blows from the WSW and W (bad directions) over 85% of the time. The resulting surf is typically small, grovelly at best, and often reduced to choppy, messy conditions by the constant onshore breeze. This is the least reliable period for surf at Arica. While a rare combination of a slightly westerly swell and lighter easterly land breeze could salvage a session, the overall outlook is minimal.

March: Spring Transition Begins, Still Windy

March marks a subtle shift as the austral autumn begins. Average swell height ticks up to 1.6m, and period increases to 13.4s, indicating more distant storm energy. Swell direction becomes slightly more favorable, with SW dropping to 63.6% and SSW rising to 35.2%. However, there is still a complete lack of from the optimal W-NW quadrant. Wind remains the biggest obstacle: WSW (45.1%) and W (43.0%) dominate, with onshore breezes over 88% of the time. The slight increase in swell size and period means the waves that do arrive are more powerful, but they are still heavily angled and wind-affected. Lighter mornings can provide occasional windows of cleaner conditions, making March a step up from summer but still far from reliable. It's a month of potential for those who are selective about session timing.
