Playa Nosara - surf spot statistics

Playa Nosara in Costa Rica offers consistent surf conditions year-round, with ground swells dominating nearly every month (92-100%), ensuring reliable wave energy. The mean swell size ranges from 1.0m in the dry season (December-February) to 1.5m in the wet season (June-September), providing a mix of manageable and more powerful waves. The best months for surfing are typically December through March, when the swell remains consistent (0.9-1.1m) and wind conditions improve significantly, with favorable offshore winds around 50-58% of the time. November also sees a slight improvement in wind conditions (51% good) while maintaining decent swell size (1.2m). In contrast, the mid-year months (May-October) bring larger swells (1.4-1.5m) but suffer from poor wind conditions (only 28-39% favorable), making them less ideal unless you’re willing to tolerate onshore winds. March and April offer slightly bigger waves (1.1-1.2m) but experience higher chances of bad winds (57-61%), making them hit-or-miss. Overall, peak season for surfers seeking optimal conditions is December to February, combining smaller but cleaner waves with the highest likelihood of good winds.

In December, Playa Nosara offers consistent surf conditions with an average swell height of 1.0m and a solid 14.0s period, indicating well-spaced, powerful waves ideal for intermediate to advanced surfers. The swell is predominantly from the SSW (17.56% of waves in the 0.5-1m range, 25.11% in 1-1.5m) and SW (19.91% in 0.5-1m, 19.40% in 1-1.5m), delivering clean, rideable waves with good shape. Wind conditions are favorable 58% of the time, with the most common winds coming from the NNE (14.16% at 10-20kph) and NE (10.15% at 10-20kph), often providing light offshore or cross-offshore effects that groom the waves. While larger swells over 1.5m are rare (less than 2% combined), the spot works reliably in the 0.5-1.5m range, making it a great destination for surfers seeking consistent, medium-sized waves with good energy. Early mornings typically have the cleanest conditions before winds pick up.
