Frost Dates and Growing Season

28 years with a frost

Across 28 years with a frost, the median last spring frost at Columbus Ohio State UNIV AP falls on 24 April and the median first autumn frost on 23 October, which leaves a median of 180 days between them.

Frost dates and growing season at Columbus Ohio State UNIV AP
Measure	Median, all years	Earliest period	Recent period (1998 to 2025)	Recent against earliest	Fitted trend
Last spring frost	24 April	n/a	24 April	n/a	-0.8 days per decade
First autumn frost	23 October	n/a	23 October	n/a	+4.7 days per decade
Growing days	180 days	n/a	180 days	n/a	+5.5 days per decade

A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.
