The origin of the term “Indian Summer” is disputed and lacks definitive historical documentation. Several theories exist, none of which have been conclusively proven.

The characteristics of Indian summers can vary from region to region, but the overall effect is often the same: a welcome respite from the cooling temperatures of autumn.
