El Frontan - surf spot statistics

El Frontón in Spain is a wave-rich destination with consistent swell year-round, but the best conditions for surfers typically occur from late autumn through early spring, specifically from October to March. During these months, ground swell dominates (68–77% of the time), providing cleaner, more powerful waves with an average swell size of 1.3–1.5m. Winter months (December–February) see the highest ground swell percentages, with December standing out at 77% ground swell and 1.5m average size—ideal for experienced surfers seeking quality waves. However, wind conditions are less favorable, with bad winds (onshore or cross-shore) occurring 81–88% of the time. November and October offer slightly better wind windows (14–16% good wind days), making them a good compromise between swell quality and rideable conditions. Spring (April–June) and summer (July–September) see a decline in ground swell, replaced by wind swell, which is less consistent and often choppier. Summer months are particularly challenging, with June–August having wind swell prevalence over 78% and bad winds 94–95% of the time, making sessions rare and less ideal. September marks a transition, with ground swell rebounding to 45%, but winds remain unfavorable (92% bad). If you’re looking for the best balance of swell power and occasional clean conditions, target October–November or February–March, though patience with wind will be necessary. For the most powerful waves, December–January delivers, but expect tough winds. Avoid summer unless you’re comfortable with weak, wind-affected surf.

December at El Frontón offers decent surf conditions, with an average swell height of 1.5m and a solid 12.2s period, providing good energy for rideable waves. The most consistent swells come from the NNW and NW directions, which contribute the majority of waves in the 1-2.5m range, with the NNW direction particularly dominant for larger swells (1.5m+). While smaller waves (under 1m) are frequent, there's a reasonable chance of scoring overhead conditions, especially when NW/NNW swells align. Wind conditions are somewhat mixed, with ideal offshore or light cross-shore winds occurring only 19% of the time. The most favorable winds tend to come from the E/ENE, but NE winds are more common and often too strong (10-30kph), creating choppy surfaces. Strong NE winds (20-40kph) are prevalent, which can degrade wave quality, but early mornings or wind shifts may offer cleaner sessions. Overall, December delivers a mix of surfable days with occasional high-quality setups when swell direction, size, and lighter winds coincide.
