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.

October at Playa Nosara offers solid surfing conditions with a consistent SW/SSW swell, averaging 1.4m in height and a strong 14.4s period, resulting in well-organized, powerful waves. The majority of swells fall in the 1-2.5m range (71% combined for SSW and SW directions), providing good overhead sets with excellent energy. Wind conditions are somewhat variable, with onshore WSW/W winds being most frequent at moderate speeds (10-30kph), creating some chop, but 32% of the time, winds align favorably for clean surf—typically lighter mornings or offshore breezes. Expect larger, punchy waves early in the month, peaking mid-season, with occasional 2.5m+ days. Target early sessions for cleaner faces, though the extended period helps maintain shape even with wind. Advanced surfers will appreciate the power and hollow sections, while intermediates should watch for stronger currents on bigger days.
