In Greek mythology, the god who personified the north wind was Boreas.
Boreas was one of the Anemoi, the group of directional wind gods. He represented the cold, powerful north wind and was often depicted as a winged, bearded man. His name is preserved in modern scientific and geographic terms, including boreal, meaning northern.
Boreas was the son of Astraeus and Eos in many mythological genealogies. He was associated with winter weather and was especially important to communities that depended on sailing and seasonal winds. In one famous Athenian story, Boreas rescued the Greeks from a Persian fleet by sending a violent storm.
The other principal Anemoi had different directions: Zephyrus was the west wind, Notus was the south wind, and Eurus was the east wind. Their roles can vary slightly between ancient sources, but Boreas’ connection with the north wind is consistent.
