Playa de San Juan - surf spot statistics

Playa de San Juan in Spain offers surfable conditions year-round, but the best months for quality waves are typically from November through March. During this period, ground swell dominates (75-85%), delivering the most consistent and powerful waves, with mean swell sizes around 1.9-2.0 meters. However, wind conditions are often less favorable, with bad winds (onshore or cross-shore) occurring over 80% of the time in peak winter months (December-February). Spring (April-May) and autumn (October) provide a balance of decent ground swell (62-65%) and slightly better wind conditions, though still challenging. Summer (June-September) sees mostly wind swell, smaller waves (1.4-1.7m), and marginally better winds, but overall conditions are weaker and less reliable for advanced surfers. For the best experience, target late autumn or early winter (November or March), when ground swell remains strong and wind conditions improve slightly compared to mid-winter. Keep in mind that the spot requires patience due to frequent onshore winds, but when conditions align, it offers powerful, clean waves ideal for experienced surfers.

February at Playa de San Juan offers consistent surf with an average swell height of 2.0m and a solid period of 13.6s, indicating well-organized, powerful waves. The dominant swell direction is from the NNW, producing the highest percentage of rideable waves (over 35% of waves are 1.5m or larger from NNW/NW). This alignment often results in clean, peeling waves suited for intermediate to advanced surfers, though sections can be fast and hollow. Wind conditions are less favorable, with only 12% of days offering ideal offshore winds (typically from the east). The prevailing winds are from the NE at 10-30kph (frequent 20-30kph), which can create choppy onshore conditions. However, the extended period helps maintain wave quality even in marginal winds. Expect a mix of shoulder-high to double-overhead days (peaking around 2-2.5m), with the best sessions occurring when NE winds ease or swing offshore. Sporadic W/WNW wind shifts may briefly improve conditions. While not a winter powerhouse, it’s a reliable spot for those comfortable in punchy beachbreak waves, especially when winds align.
