Playa Avellanes - surf spot statistics

Playa Avellanes in Costa Rica offers consistent surf conditions year-round, with ground swells dominating nearly every month, rarely dropping below 92%. This ensures reliable wave energy, though the swell size remains moderate, averaging between 1.2m and 1.5m. The best time to surf here depends on a balance between swell consistency, size, and favorable winds. From June to August, the swell peaks slightly in size (1.4m-1.5m), but wind conditions are most favorable in July (51% good winds) and November (54% good winds), making these standout months. While winter months (December-February) maintain solid ground swells, they suffer from higher onshore wind interference (61-64% bad winds). Late-year months like November offer the best compromise—solid swells, decent size, and the highest chance of offshore or light winds. Early summer (June-August) is another solid window, with July being particularly reliable for cleaner conditions. If prioritizing wave quality over size, November stands out, while those seeking slightly larger waves may prefer mid-year despite somewhat riskier winds. Overall, Playa Avellanes delivers dependable surf, but late-year and mid-summer months provide the most optimal combination of conditions.

In January, Playa Avellanes offers consistent surf with an average swell height of 1.2m and a solid 13.6s period, providing well-organized, rideable waves. The dominant swell directions are SSW, SW, and WSW, with the majority of waves falling in the 1-1.5m range (21.93%, 26.29%, and 7.23%, respectively), ensuring decent size and energy. Larger waves (1.5-2.5m) are less frequent but still present, particularly from the SSW and SW directions. Wind conditions are favorable 38% of the time, with lighter winds (0-20kph) coming mostly from the NNE and NE, though stronger NE winds (20-40kph) can occasionally create chop. Offshore or light cross-shore winds are most likely from the W-NW sector, but the predominant NE wind pattern can sometimes be onshore. Overall, January delivers reliable, mid-sized surf with good power, best suited for intermediate to advanced surfers when winds cooperate. Expect a mix of clean and slightly wind-affected sessions, with the best conditions occurring during lighter wind windows.
