Across 23 years with a frost, the median last spring frost at Roland falls on 19 May and the median first autumn frost on 16 September, which leaves a median of 121 days between them.

Frost dates and growing season at Roland
Measure	Median, all years	Earliest period	Recent period (1952 to 1975)	Recent against earliest	Fitted trend
Last spring frost	19 May	n/a	19 May	n/a	n/a
First autumn frost	16 September	n/a	16 September	n/a	n/a
Growing days	121 days	n/a	121 days	n/a	n/a

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.
