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
78 years with a frostAcross 78 years with a frost, the median last spring frost at King Salmon falls on 30 May and the median first autumn frost on 7 September, which leaves a median of 102 days between them.
In 1995 to 2025 the median growing season was 92 days. That is 11 days fewer than in 1947 to 1976.
Fitted over all years, the growing season changes by -1.7 days per decade at this station.
| Measure | Median, all years | Earliest period (1947 to 1976) | Recent period (1995 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 30 May | 28 May | 2 June | 5 days later | +0.5 days per decade |
| First autumn frost | 7 September | 8 September | 5 September | 3 days earlier | -1.3 days per decade |
| Growing days | 102 days | 103 days | 92 days | 11 days fewer | -1.7 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
80 years, 1944 to 2025A day with at least 24.7 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 43.4 mm (1.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 24.7 mm (1.0 in) | |
| 5 years | 30.6 mm (1.2 in) | |
| 10 years | 34.2 mm (1.3 in) | |
| 25 years | 38.2 mm (1.5 in) | |
| 50 years | 40.9 mm (1.6 in) | |
| 100 years | 43.4 mm (1.7 in) | Longer than the 80 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, 80 years of values from 1944 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: 42.4 mm (1.7 in) in 1960; 40.4 mm (1.6 in) in 1994; 36.8 mm (1.4 in) in 1948.
Climate Twins
2010 to 2025 against 1961 to 1990Over 2010 to 2025, King Salmon had a mean temperature of 2.5 C (36.5 F) and 616.3 mm (24.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are McCulloch (Canada, 2,583 km away), Gol - Stake (Norway, 6,680 km away) and Ruxton Park (United States, 4,236 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| McCulloch | Canada | 2,583 km (1,605 mi) | 2.7 C (36.9 F) | 676.9 mm (26.6 in) | 0.97 |
| Gol - Stake | Norway | 6,680 km (4,151 mi) | 2.5 C (36.5 F) | 546.5 mm (21.5 in) | 1.08 |
| Ruxton Park | United States | 4,236 km (2,632 mi) | 2.5 C (36.4 F) | 600.6 mm (23.6 in) | 1.09 |
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.
