Oviedo sits in Spain’s ‘Green Spain’ region along the northern coast, where an oceanic climate brings the country’s highest and most evenly distributed rainfall, driven by Atlantic weather systems arriving through the Bay of Biscay.
Inland from Gijon in Asturias, the city’s surrounding mountains can intensify rainfall from Atlantic storm systems. Steep coastal terrain and numerous short, fast rivers mean that even routine Atlantic storms can raise water levels quickly, and radar is a standard tool AEMET uses alongside river gauges here.
