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

29 years with a frost

Across 29 years with a frost, the median last spring frost at Humboldt falls on 25 May and the median first autumn frost on 9 September, which leaves a median of 109 days between them.

Fitted over all years, the growing season changes by +8.2 days per decade at this station.

Frost dates and growing season at Humboldt
Measure	Median, all years	Earliest period	Recent period (1914 to 1973)	Recent against earliest	Fitted trend
Last spring frost	25 May	n/a	25 May	n/a	-2.8 days per decade
First autumn frost	9 September	n/a	9 September	n/a	+5.4 days per decade
Growing days	109 days	n/a	109 days	n/a	+8.2 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.
