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 April, Playa Nosara offers consistent surf conditions with a predominant swell coming from the SSW and SW directions, which aligns well with the beach's exposure. The average swell height is 1.2m, paired with a strong 15-second period, ensuring well-spaced, clean waves with good energy. Most waves (over 72%) fall in the 0.5-1.5m range, providing manageable yet punchy surf, while larger sets occasionally reach 2-2.5m (about 1.3% of the time). Wind conditions are relatively favorable, with offshore or light cross-shore flows occurring 39% of the time—typically from the NNE to ENE in the mornings before shifting to variable onshore (SW/SSW) later. However, moderate onshore winds (10-20kph) from the SW/SSW can affect afternoons, so dawn patrols often deliver the cleanest sessions. Overall, April is a reliable month for intermediate to advanced surfers, offering a mix of playful mid-sized waves and occasional overhead days, best capitalized on early before winds pick up.
