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

82 years with a frost

Across 82 years with a frost, the median last spring frost at Karlstad-Airport falls on 10 May and the median first autumn frost on 29 September, which leaves a median of 143 days between them.

In 1996 to 2025 the median growing season was 145 days. That is 5 days more than in 1943 to 1973.

Fitted over all years, the growing season changes by +0.5 days per decade at this station.

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.
