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 April, Playa Tamarindo offers consistent surf conditions with an average swell height of 1.2m and a solid period of 14.9s, indicating well-formed, energy-rich waves. The dominant swell direction is from the SSW and SW, contributing to 78% of the waves in the 0.5-2.5m range, with the majority (40%) peaking at 1-1.5m. This setup ensures reliable, rideable waves, often with good shape thanks to the long period. Wind conditions are favorable 43% of the time, with the most common onshore breezes coming from the NE (8.2% at 10-20kph) and ENE (6.5% at 10-20kph). While NE winds can occasionally create chop, lighter winds from the E or SE provide cleaner conditions. Expect a mix of waist-to-head-high waves, with some bigger sets, making it suitable for intermediate to advanced surfers. Mornings often see lighter winds, enhancing session quality. Overall, April delivers dependable surf with good power and occasional offshore wind windows.
