K59 - surf spot statistics

K59 in El Salvador is a consistent year-round surf spot with a strong dominance of ground swell, averaging between 92% and 100% through the year, ensuring high-quality waves with minimal wind swell interference. The best months for surfing at K59 are March through September, when the mean swell size increases, peaking at 1.5m in September. During this period, the swell is most reliable, with March offering a good balance of wave size (1.1m) and slightly better wind conditions (47% good winds). From April to September, the swell size remains strong (1.2m–1.5m), though wind conditions become less favorable, with bad winds occurring 55–61% of the time. The optimal time for cleanest conditions is typically March and November, when the chance of good winds is highest (47–49%) while still maintaining solid swell size (1.1m). The worst wind conditions occur from May to September, with June and September seeing only 39% good winds. December to February are decent, but with smaller waves (0.9m–1.0m) and moderately unfavorable winds (53–55% bad winds). Overall, advanced surfers will find the most powerful and consistent surf from April to September, while those preferring cleaner conditions should target March or November.

April at K59 (El Salvador) offers fairly consistent surf with a solid mix of rideable conditions. The average swell height is 1.2m with a strong 14.8s period, indicating well-spaced, powerful waves, especially given the dominant SSW swell direction (accounting for 69% of waves in the 1-1.5m range and 13% in the 0.5-1m range). The majority of swells come from the southern quadrant, producing clean, organized waves suited for intermediate to advanced surfers. Cross-shore or light offshore winds from the NNE to E directions contribute to favorable conditions about 45% of the time, but be mindful of occasional SSW-WSW winds (10-30kph) that can create chop. While larger sets are rare (only 7% of SSW swells reaching 1.5-2m), the consistency of chest-high to head-high waves combined with the long period makes April a reliable month for quality sessions, particularly on mid to high tides for optimal shape. Wind direction variability means early mornings often provide the cleanest conditions before sea breezes kick in.
