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

62 years with a frost

Across 62 years with a frost, the median last spring frost at Storlien falls on 17 June and the median first autumn frost on 9 August, which leaves a median of 56 days between them.

In 1932 to 1963 the median growing season was 59 days. That is 7 days more than in 1900 to 1929.

Fitted over all years, the growing season changes by +1.1 days per decade at this station.

Frost dates and growing season at Storlien
Measure	Median, all years	Earliest period (1900 to 1929)	Recent period (1932 to 1963)	Recent against earliest	Fitted trend
Last spring frost	17 June	18 June	15 June	3 days earlier	-0.6 days per decade
First autumn frost	9 August	7 August	10 August	3 days later	+0.5 days per decade
Growing days	56 days	52 days	59 days	7 days more	+1.1 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.

Rainfall Return Levels

67 years, 1878 to 1963

A day with at least 35.3 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 69.6 mm (2.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Storlien: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	35.3 mm (1.4 in)
5 years	44.8 mm (1.8 in)
10 years	51.0 mm (2.0 in)
25 years	58.6 mm (2.3 in)
50 years	64.1 mm (2.5 in)
100 years	69.6 mm (2.7 in)	Longer than the 67 years of record

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 67 years of values from 1878 to 1963.

A return level is an estimate. It is least reliable for the long periods, 50 and 100 years, and for any period longer than the record behind the fit, where the fit has to reach past the largest day actually observed. It is not a forecast.

The largest wettest-day totals in the fit: 67.2 mm (2.6 in) in 1953; 62.6 mm (2.5 in) in 1905; 58.8 mm (2.3 in) in 1924.
