By the meteorological calendar, spring starts on 1 March. The seasons are defined as spring (March, April, May), summer (June, July, August), autumn (September, October, November) and winter (December, January, February). The astronomical spring begins on 20 March 2017 and ends on 20 June 2017.
Tornado season starts roughly in March and is at its most active from May to June, but plenty of tornado outbreaks buck that pattern. While some tornado seasons start out busy, they can peter out, like the 2012 season did.
