Isla Uvita - surf spot statistics

Isla Uvita in Costa Rica is a wave magnet that primarily relies on wind swells, with ground swells being rare throughout the year. The best months for surfing here are from December to March and July, when the swell consistency, size, and wind conditions align most favorably. During these months, the mean swell size ranges from 1.4m to 1.6m, with wind conditions being good 61–64% of the time, minimizing onshore disruptions. January and December stand out as the most reliable, offering the highest percentage of good wind days and consistent wind swell presence at 98%. February and March follow closely with similar swell sizes and slightly lower but still favorable wind conditions. July is another solid month, with a swell size of 1.5m and 63% good wind days. The worst conditions occur from September to November, particularly in October, when swell activity drops significantly (mean size 0.7m), and bad wind conditions dominate (60%). May and April also see a decline in swell size and wind quality, making them less ideal for advanced surfers seeking powerful waves. Overall, peak season surfers should target the dry season months (December–March) for the most consistent surf, while those willing to compromise on size can still find rideable waves in the transitional months like June and August. Avoid the rainy season’s tail end (September–October) when swell energy dissipates and onshore winds prevail.

February at Isla Uvita offers consistent surf conditions with an average swell height of 1.5m and a solid 8.6s period, providing well-organized waves ideal for intermediate to advanced surfers. The swell predominantly comes from ENE (80.5% combined from 1-2.5m), delivering clean, rideable waves in the 1-2.5m range. Smaller swells from NE and NNE contribute occasionally, while other directions are negligible. Wind conditions are favorable 61% of the time, with light to moderate speeds (0-20kph) from NNE, NE, and ENE, ensuring clean faces. Stronger winds from SW and WSW (14-20kph) occur but are less frequent. Overall, February is a reliable month with good wave quality, manageable size, and a high likelihood of offshore or light cross-shore winds. *Note: Data assumes typical seasonal patterns; always check real-time forecasts for precision.*
