According to folk signs, on St. Lyudmila's Day you can make a weather forecast for the winter.
Thunder on this day is a harbinger of a cold and snowless winter.
If it is warm on Lyudmila and Efimiya, then the winter will also be warm.
Also, a warm Lyudmila day means that winter will come late.
If jackdaws gather in flocks, clear weather is expected.
