Playa de la Canteria in Spain offers varying surf conditions throughout the year, with the best months for surfing primarily falling within the winter and early spring period. The data shows that ground swells, which produce higher-quality waves, dominate from November to March, peaking in February (78%) and December (77%). These months also feature the largest mean swell sizes, averaging around 1.7m, providing consistent and powerful waves for experienced surfers. However, the wind conditions during these months are often unfavorable, with bad winds occurring over 80% of the time in January, February, and December, making clean surf sessions less frequent. The shoulder seasons, particularly April and October, strike a balance with decent ground swell presence (50-55%) and slightly better wind conditions, though still challenging. Summer months (May to September) see a steep decline in ground swells, replaced by wind swells that often create choppier, less ideal waves. June stands out with the highest wind swell dominance (92%) but the smallest mean swell size (1.4m), making it less appealing for serious surfers. In summary, the optimal time to surf at Playa de la Canteria is from late autumn to early spring (November to March) when ground swells are most consistent, but surfers must be prepared to navigate frequent onshore winds. For those willing to compromise on wave quality, April and October offer a slightly better wind-to-swell ratio, while the summer months are best suited for beginners or those seeking smaller, messier waves.
