Isla Chepillo - surf spot statistics

Isla Chepillo in Panama experiences consistent ground swell throughout the year, with the highest probability occurring from April to May (68-72%) and August (67%). The swell is predominantly ground-driven, with minimal wind swell influence, ensuring cleaner wave conditions. However, the mean swell size remains modest at around 0.5-0.6 meters, indicating mostly small to medium waves. Wind conditions are challenging year-round, with the highest likelihood of favorable winds occurring in April (29% good conditions) and the lowest in January-February (14-16%). Despite this, strong onshore winds (bad conditions) dominate, averaging 71-86% probability across all months, peaking in January-February. The best months for surfing are likely April and May due to the highest ground swell consistency and slightly better wind chances (27-29% favorable), though surfers should expect frequent wind interference. Late-year months like November and December see a drop in ground swell (51-57%) and persistent poor winds, making them less ideal. Overall, Isla Chepillo is a spot with reliable but small swells, best surfed in mid-year months when ground swell peaks and wind conditions are marginally better, though wind remains a limiting factor.

December at Isla Chepillo offers fairly small but clean conditions for surfers, with an average swell height of 0.5m and a solid 12.6s period, indicating well-spaced and organized waves. The swell is predominantly from the S and SSW directions, contributing most of the rideable waves in the 0.5-1m range (37.12% and 14.82% respectively), with occasional slightly larger sets up to 1.5m. The consistency is decent, though larger swells above 2m are rare. Wind conditions are a mix, with only 21% of the time being ideal for surfing—typically light winds from favorable directions. However, moderate to strong northerly winds (N, NNE, NNW) are common, creating choppy conditions, especially above 20kph. For surfers, this means shorter sessions when winds align, prioritizing early mornings or protected spots. Overall, December delivers manageable waves for intermediate surfers but lacks consistency and size for advanced riders seeking powerful surf.
