Costa Navarino in Greece is primarily a windswell-driven surf spot, with very little ground swell influence throughout the year. The best months for surfing here are during the winter season, from November to February, when windswell frequency peaks at 69-76%, offering the most consistent waves. Mean swell size during these months ranges from 1.0 to 1.1 meters, which is modest but surfable, particularly for intermediate surfers. However, wind conditions are generally unfavorable, with bad winds prevailing 86-88% of the time, making clean surf sessions rare. From March to October, surfable conditions decline significantly—windswell frequency drops below 70%, and swell size diminishes to 0.6-0.8 meters, making waves smaller and less reliable. Summer months (May to September) are particularly poor, with windswell dropping to 41-51% and bad wind conditions exceeding 90% of the time. While late autumn and winter provide the highest chance of rideable waves, surfers should be prepared for frequent onshore winds. Overall, Costa Navarino is not a premier surf destination, but if you're in the area, the winter months offer the best—albeit still inconsistent—opportunities for waves.
