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.

October at Playa de San Juan offers decent surf conditions with an average swell height of 1.6m and a solid period of 11.4s, indicating consistent and well-formed waves. The swell direction is predominantly from the north and northwest, with the NNW sector producing the highest percentage of rideable waves (20.87% in the 1-1.5m range and 15.77% in the 1.5-2m range). The strongest swells (over 2.5m) are rare but most likely from the NNW direction. Wind conditions are less favorable, with only 20% of days offering ideal offshore or light cross-shore winds, mostly from the northeast to east. However, moderate to strong onshore winds (10-30kph) from the NE, ENE, and E directions are common, which can create choppy conditions. Surfers can expect a mix of clean and messy sessions, with the best days occurring when winds are light or offshore, allowing the consistent NNW-NW swell to produce quality waves. Overall, October provides fair opportunities for intermediate to advanced surfers, but wind conditions will dictate the best windows for good surf.
