“Indian Summer” is a term used to describe a period of unseasonably warm, dry, and sunny weather that occurs in late autumn, typically during September and October in North America. During an Indian Summer, temperatures rise above the normal range for the season, and the days often feel more like summer than fall.

The origin of the term is somewhat debated, but it likely has its roots in early American settlers’ observations of Native American weather patterns. Indian Summers are characterized by clear skies, warm temperatures during the day, cool and crisp nights, and a lack of precipitation. This weather phenomenon can be quite pleasant and is often associated with a final burst of outdoor activities before the onset of colder winter weather.
