Külmora

Külmora is a term found in Baltic and Finnic folklore that refers to a winter spirit associated with cold weather and frost. The name is linked to phenomena of freezing and seasonal cycles in rural oral traditions of Estonia, Latvia, Finland, and adjacent regions. In traditional narratives, külmora is imagined as a solitary, elusive being that dwells in snowfields, icy caves, or high mountains and exerts influence over weather patterns, frost, and ice. Encounters with külmora are typically described as warnings or tests rather than acts of kindness, and are often used to explain sudden temperature drops, unexpected frosts, or blizzards. Depending on the tale, külmora may be seen as malevolent, indifferent to humans, or as a guardian of winter's balance who enforces respect for the cold season.

In regional folklore, the külmora motif sometimes appears alongside other frost spirits and winter deities, reflecting a cultural emphasis on endurance and resourcefulness during harsh winters. The figure has also found expression in modern literature, art, and music inspired by winter landscapes.

Scholarly attention to külmora is limited and largely part of broader studies of Finnic and Baltic winter spirits. As with many oral traditions, variants exist across communities, and the exact attributes of külmora can differ from one tale to another.
