Question:
Where does the term "Indian summer" come from, and what determines when we have one?



Replies:
I do not know where the term Indiana summer comes from. It is defined as a period of fair mild weather in autumn after the first widespread frost or freeze of the season. It is characterized by sunny skies. It is usually caused by a large persistent or slow moving high pressure system.
