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.

In August, Playa de San Juan offers relatively consistent surf conditions with an average swell height of 1.6m and a decent period of 7.7s, suggesting workable waves for intermediate to advanced surfers. The swell is predominantly from the north and NNE, with the majority of waves falling in the 1-2m range (around 60% of the time), providing decent energy and shape. Larger sets occasionally reach 2-2.5m, but waves over 2.5m are rare. Wind conditions are somewhat variable, with only 24% of the time being ideal for surfing—typically when winds are light (0-10kph) or favorably offshore. The most common winds come from the NE to ENE at 10-30kph, which can create choppy or cross-shore conditions. Surfers should watch for morning sessions when winds are lighter, as afternoons often see stronger breezes. Overall, August delivers rideable waves but requires patience and timing due to inconsistent wind quality.
