| Annual mean temperature | 0.2 C (0.1 to 0.3) per decade | 0.3 F (0.1 to 0.5) per decade | 1943 to 2024 | 78 | Rise |
| Mean daily maximum | 0.2 C (0.1 to 0.3) per decade | 0.3 F (0.1 to 0.5) per decade | 1943 to 2024 | 78 | Rise |
| Mean daily minimum | 0.2 C (0.1 to 0.3) per decade | 0.3 F (0.1 to 0.5) per decade | 1943 to 2024 | 78 | Rise |
A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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 Gulkana AP falls on 5 June and the median first autumn frost on 18 August, which leaves a median of 74 days between them.
In 1993 to 2024 the median growing season was 75 days. That is 2 days fewer than in 1943 to 1972.
Fitted over all years, the growing season changes by -0.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1943 to 1972) | Recent period (1993 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 5 June | 2 June | 7 June | 5 days later | +0.8 days per decade |
| First autumn frost | 18 August | 17 August | 20 August | 3 days later | +0.6 days per decade |
| Growing days | 74 days | 77 days | 75 days | 2 days fewer | -0.1 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
81 years, 1943 to 2024A day with at least 22.2 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 51.5 mm (2.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 22.2 mm (0.9 in) | |
| 5 years | 30.1 mm (1.2 in) | |
| 10 years | 35.3 mm (1.4 in) | |
| 25 years | 41.8 mm (1.6 in) | |
| 50 years | 46.7 mm (1.8 in) | |
| 100 years | 51.5 mm (2.0 in) | Longer than the 81 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, 81 years of values from 1943 to 2024.
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: 52.3 mm (2.1 in) in 1951; 51.8 mm (2.0 in) in 1972; 51.1 mm (2.0 in) in 1976.

Climate Twins
2008 to 2024 against 1961 to 1990Over 2008 to 2024, Gulkana AP had a mean temperature of -2.0 C (28.5 F) and 351.1 mm (13.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Big Delta AP (United States, 204 km away), Mugur-Aksy (Russia, 6,568 km away) and College Obsy (United States, 323 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Big Delta AP | United States | 204 km (127 mi) | -2.3 C (27.8 F) | 301.5 mm (11.9 in) | 1.09 |
| Mugur-Aksy | Russia | 6,568 km (4,081 mi) | -2.4 C (27.6 F) | 163.4 mm (6.4 in) | 1.49 |
| College Obsy | United States | 323 km (201 mi) | -2.5 C (27.5 F) | 309.9 mm (12.2 in) | 1.59 |
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.
