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 frostAcross 73 years with a frost, the median last spring frost at Bettles AP falls on 24 May and the median first autumn frost on 26 August, which leaves a median of 90 days between them.
In 1995 to 2024 the median growing season was 90 days. That is 4 days fewer than in 1952 to 1981.
Fitted over all years, the growing season changes by +0.7 days per decade at this station.
| Measure | Median, all years | Earliest period (1952 to 1981) | Recent period (1995 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 24 May | 24 May | 23 May | 1 day earlier | +0.2 days per decade |
| First autumn frost | 26 August | 23 August | 25 August | 2 days later | +0.9 days per decade |
| Growing days | 90 days | 94 days | 90 days | 4 days fewer | +0.7 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
73 years, 1952 to 2024A day with at least 21.5 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 59.9 mm (2.4 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 73 years of values from 1952 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: 75.2 mm (3.0 in) in 1994; 49.0 mm (1.9 in) in 1958; 45.0 mm (1.8 in) in 1953.
Climate Twins
2010 to 2024 against 1961 to 1990Over 2010 to 2024, Bettles AP had a mean temperature of -4.2 C (24.5 F) and 441.7 mm (17.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Tanana AP (United States, 196 km away), Eagle (United States, 525 km away) and McGrath AP (United States, 480 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Tanana AP | United States | 196 km (122 mi) | -4.3 C (24.2 F) | 330.4 mm (13.0 in) | 0.89 |
| Eagle | United States | 525 km (326 mi) | -4.4 C (24.2 F) | 302.9 mm (11.9 in) | 1.32 |
| McGrath AP | United States | 480 km (298 mi) | -3.6 C (25.4 F) | 407.4 mm (16.0 in) | 1.38 |
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.
