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.

December at Playa Avellanes offers solid surf conditions with a typical mix of consistency and quality. The average swell height of 1.2m combined with a favorable 13.7s period ensures well-spaced, surfable waves, often producing clean, powerful rides. The dominant swell directions come from the SSW and SW (over 60% combined for waves 1-2.5m), delivering the best energy and shape, while smaller contributions from other directions help maintain variety. Wind conditions are workable, with 46% of the time being ideal—mostly light offshore or cross-shore breezes from the NE, ENE, or N, though NE winds can occasionally strengthen to 20-30kph (22.5% of the time), which may create choppier surfaces. Waves in the 1-1.5m range are most frequent (peaking at 31.45% from SW), offering manageable yet punchy walls, while larger sets (1.5-2.5m) appear often enough to challenge advanced surfers. Overall, December is a reliable month here, with a high probability of scoring clean, medium-sized waves and enough swell diversity to keep sessions interesting. Wind discipline is key, but when it aligns, expect high-performance walls and occasional hollow sections.
