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

65 years with a frost

Across 65 years with a frost, the median last spring frost at Wrangell AP falls on 23 April and the median first autumn frost on 19 October, which leaves a median of 172 days between them.

In 1968 to 2011 the median growing season was 185 days. That is 14 days more than in 1919 to 1961.

Fitted over all years, the growing season changes by +3.5 days per decade at this station.

Frost dates and growing season at Wrangell AP
Measure	Median, all years	Earliest period (1919 to 1961)	Recent period (1968 to 2011)	Recent against earliest	Fitted trend
Last spring frost	23 April	28 April	22 April	6 days earlier	-1.5 days per decade
First autumn frost	19 October	14 October	24 October	10 days later	+2.0 days per decade
Growing days	172 days	171 days	185 days	14 days more	+3.5 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, 1919 to 2011

A day with at least 69.1 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 134.9 mm (5.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Wrangell AP: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	69.1 mm (2.7 in)
5 years	86.1 mm (3.4 in)
10 years	97.6 mm (3.8 in)
25 years	112.4 mm (4.4 in)
50 years	123.6 mm (4.9 in)
100 years	134.9 mm (5.3 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 1919 to 2011.

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: 139.7 mm (5.5 in) in 1993; 129.0 mm (5.1 in) in 2005; 114.6 mm (4.5 in) in 1962.
