Frost dates and growing season at Resolution Island
Measure	Median, all years	Earliest period	Recent period (1930 to 1960)	Recent against earliest	Fitted trend
Last spring frost	30 June	n/a	30 June	n/a	+0.2 days per decade
First autumn frost	1 July	n/a	1 July	n/a	+0.6 days per decade
Growing days	1 day	n/a	1 day	n/a	+0.4 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.
