At its core, the definition is technical. The National Weather Service and climatologists agree on specific criteria for a true Indian Summer: it must follow a killing frost—a period of freezing temperatures that ends the growing season. The weather during this spell must be abnormally warm, with clear skies, hazy sunshine, and light or calm winds. Crucially, it occurs in mid-to-late autumn, typically between late October and November in the Northern Hemisphere. It is not a second spring, but a final, borrowed memory of summer, lasting anywhere from a few days to two weeks before winter settles in for good.
In literature and poetry, it frequently serves as a metaphor for: Achieving goals later in life. definition indian summer
