Playa Tamarindo - surf spot statistics

Playa Tamarindo in Costa Rica benefits from consistent year-round swell, primarily ground swell, which dominates the conditions with over 90% presence in every month. The swell size remains steady, averaging between 1.1m and 1.4m, peaking slightly from May to September. Wind conditions vary more noticeably, with the best wind reliability occurring from May to August when favorable winds are present around 50-55% of the time. The worst wind conditions are from December to March, when onshore winds dominate, reducing surf quality despite solid swell. April stands out as a transition month with 100% ground swell and improving wind conditions. For advanced surfers seeking the most reliable mix of swell and wind, the window from May to August offers the best balance, with slightly larger waves and a higher chance of offshore or light onshore winds. September and October still provide solid swell but see a marginal drop in wind quality. While Tamarindo rarely has flat spells, those prioritizing glassy conditions should focus on mid-year, whereas those comfortable with chop may find decent waves year-round.

In May, Tamarindo offers surfers consistent conditions with an average swell height of 1.3m and a solid period of 14.9s, indicating powerful, well-spaced waves. The swell direction is predominantly from the SSW (35.59% of waves in the 1-1.5m range) and SW (27.58%), creating favorable, rideable waves. Larger sets (1.5-2.5m) occur around 20% of the time, providing punchy sections for more advanced surfers. Wind conditions are ideal 48% of the time, with light to moderate offshore or cross-shore breezes mainly from the NE, ENE, and E (5-20kph). Early mornings often see the cleanest conditions before winds pick up. Overall, May delivers reliable surf with a mix of mid-sized waves and occasional overhead sets, best suited for intermediate to advanced surfers who can handle the occasional bump from onshore SW winds later in the day.
