Annual rainfall exceeds 1,200 mm over more than 130 rainy days, peaking in autumn and winter. Atlantic fronts arrive in succession, producing persistent rain.

NW storms can generate big waves at El Sardinero, La Magdalena and the seafront. A warm, dry southerly wind can cause foehn episodes with unusually high winter temperatures.
