In the United States and Canada, an Indian summer typically occurs between late September and early November, with the peak warmth usually happening in October. During this time, a high-pressure system dominates the region, leading to clear skies, light winds, and above-average temperatures, often 10-20°F (5-10°C) higher than usual. This period of warm weather can last from a few days to several weeks.

It is most common in the Midwest, the Northeast, and the Great Lakes regions—areas that experience distinct seasonal changes. In the Southern states, where the transition from summer to winter is subtle, the term is rarely used because the "return" of warmth is hardly noticeable.
