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.

June at Playa Avellanes offers solid surf conditions with consistent swell and manageable winds. The average swell height is 1.5m with a strong 14.9s period, indicating powerful, well-spaced waves—ideal for experienced surfers. Most swells come from the SW and SSW directions (combined ~87% of waves), producing clean, rideable waves in the 1-2.5m range. Wind conditions are favorable 43% of the time, with light to moderate offshore or cross-offshore breezes (predominantly NE to E in the morning, shifting SW later). However, NE winds can occasionally pick up (20-30kph range ~6-7% of the time), potentially creating chop. Swell consistency is high, with only rare flat spells. Expect shoulder-to-head-high waves, occasionally overhead, with the best sessions likely in the mornings before wind interference. Overall, June delivers reliable, high-quality surf here, though wind management is key for optimal sessions.
