Nuberu

The Nuberu, also spelled Nubero, is the personification of storm clouds in Asturian folklore from northern Spain, imagined as an old, wild-haired man dressed in animal skins who rides or drives the clouds across the sky, hurling hail, lightning, and rain down on the fields below. Farmers traditionally blamed sudden hailstorms that ruined crops on his mischief or anger, and villages recited a protective conjure passed down for generations: "Detente, nuble y nublado, que Dios puede más que el diablo" ("Stop, cloud and storm, for God is more powerful than the devil"), often paired with blessed branches or church bells rung specifically to ward him off. Folklorist Constantino Cabal catalogued these beliefs in his 1925 study La mitología asturiana. Unlike menacing cryptids, the Nuberu was often treated with a mix of fear and dark humor, appearing in sayings and children's tales as a grumpy weather spirit rather than a physical predator. The legend likely grew from the very real, sudden violence of mountain storms in Asturias's rugged terrain, giving a face and a will to unpredictable weather that could otherwise seem like blind bad luck.
