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.
