Nuberos live in the clouds or travel in them. Responsible for rain, hail and storms, they enjoy causing damage in the fields, often collecting the harvest and carrying it away. However, they are often generous to those who help them when they come down to earth, especially in the case of couples. He is a widespread character throughout Spain and takes various forms. Almost always of small stature and dressed in rags, he lends his name on the Cantabrian coast to physically unattractive people. It has always been able to be summoned in one way or another. One of them is through the sound of the bells, another through a priest who throws a shoe to a cloud so that it unloads only where it falls. One could also burn a blessed laurel on Palm Sunday, or place it on the head during the storm, light a candle on Holy Thursday, and put an ax on the threshold with the edge upwards.

In Asturias he receives the name of Juan Cabrito and travels from Egypt, where he lives with his family in a house located on top of a mountain with permanent fog. It is said that he returns with favor the help received after falling from a cloud and being welcomed by some farmers, when after a few years the boat in which one of them was traveling sinks, not only welcomes him in his house but also returns him to his village in time to prevent the marriage of his wife to another, as they believed him dead.

In the Basque Country it is called Aidegatxo, Ortzia or Odei. He is responsible for the formation of storms, which are unleashed when he chooses. Using incantations and signaling with his arm, he can be persuaded to change the place where the storm breaks out.
