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 at Stanley
Measure	Median, all years	Earliest period	Recent period (1984 to 2025)	Recent against earliest	Fitted trend
Last spring frost	29 June	n/a	29 June	n/a	0.0 days per decade
First autumn frost	3 July	n/a	2 July	n/a	-0.3 days per decade
Growing days	7 days	n/a	7 days	n/a	-0.3 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.
