Situated on level or slightly rolling terrain in central Indiana east of the White River, Indianapolis has a temperate climate; because of even distribution of precipitation throughout the year, there are no pronounced wet or dry seasons. Summers are very warm, and the invasion of polar air from the north often produces frigid winter temperatures with low humidity. Two to three times each winter, snowfalls average three inches or more.
