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 January, Playa Tamarindo offers consistent surf conditions with an average swell height of 1.2m and a solid period of 13.5s, providing clean, well-spaced waves. The predominant swell directions are SW (23.77% of waves in the 1-1.5m range) and SSW (20.76% in the same range), delivering chest-high to head-high waves with occasional bigger sets. The WSW and W swells contribute smaller but surfable waves. Wind conditions are less favorable, with only 29% of days offering ideal offshore or light cross-shore winds (typically NE at 10-20kph). However, NE winds above 20kph (22.36% occurrence) can create choppy conditions. Expect manageable crowds and reliable surf, best suited for intermediate to advanced surfers when winds cooperate. Early mornings often provide the cleanest sessions before winds pick up.
