Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Frost Dates and Growing Season

20 years with a frost

Across 20 years with a frost, the median last spring frost at Foremost falls on 17 May and the median first autumn frost on 23 September, which leaves a median of 130 days between them.

Frost dates and growing season at Foremost
Measure	Median, all years	Earliest period	Recent period (1961 to 1983)	Recent against earliest	Fitted trend
Last spring frost	17 May	n/a	17 May	n/a	n/a
First autumn frost	23 September	n/a	23 September	n/a	n/a
Growing days	130 days	n/a	130 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.
