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

73 years with a frost

Across 73 years with a frost, the median last spring frost at Cold Bay AP falls on 23 May and the median first autumn frost on 3 October, which leaves a median of 130 days between them.

In 1996 to 2025 the median growing season was 125 days. That is 7 days fewer than in 1951 to 1982.

Fitted over all years, the growing season changes by -1.2 days per decade at this station.

Frost dates and growing season at Cold Bay AP
Measure	Median, all years	Earliest period (1951 to 1982)	Recent period (1996 to 2025)	Recent against earliest	Fitted trend
Last spring frost	23 May	23 May	1 June	9 days later	+1.1 days per decade
First autumn frost	3 October	3 October	29 September	4 days earlier	-0.1 days per decade
Growing days	130 days	132 days	125 days	7 days fewer	-1.2 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.

Rainfall Return Levels

74 years, 1951 to 2025

A day with at least 45.3 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 108.0 mm (4.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Cold Bay 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	45.3 mm (1.8 in)
5 years	60.7 mm (2.4 in)
10 years	71.4 mm (2.8 in)
25 years	85.6 mm (3.4 in)
50 years	96.6 mm (3.8 in)
100 years	108.0 mm (4.3 in)	Longer than the 74 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, 74 years of values from 1951 to 2025.

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: 124.5 mm (4.9 in) in 1968; 96.0 mm (3.8 in) in 2000; 84.1 mm (3.3 in) in 1972.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Cold Bay AP had a mean temperature of 4.7 C (40.5 F) and 1,070.1 mm (42.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Nord-Solvaer (Norway, 6,489 km away), Smola - Moldstad (Norway, 6,799 km away) and Keflavik (Iceland, 6,329 km away).

Climate twins of Cold Bay AP: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Nord-Solvaer	Norway	6,489 km (4,032 mi)	5.5 C (41.9 F)	1,143.2 mm (45.0 in)	1.13
Smola - Moldstad	Norway	6,799 km (4,225 mi)	5.5 C (41.9 F)	1,135.5 mm (44.7 in)	1.26
Keflavik	Iceland	6,329 km (3,933 mi)	4.6 C (40.2 F)	1,258.7 mm (49.6 in)	1.27

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
