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
55 years with a frostAcross 55 years with a frost, the median last spring frost at Kemmerer 2N falls on 21 June and the median first autumn frost on 26 August, which leaves a median of 66 days between them.
Fitted over all years, the growing season changes by +1.7 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1982 to 2023) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 June | n/a | 20 June | n/a | -0.2 days per decade |
| First autumn frost | 26 August | n/a | 27 August | n/a | +1.4 days per decade |
| Growing days | 66 days | n/a | 67 days | n/a | +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
73 years, 1934 to 2025A day with at least 21.5 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 53.9 mm (2.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 21.5 mm (0.8 in) | |
| 5 years | 29.0 mm (1.1 in) | |
| 10 years | 34.3 mm (1.4 in) | |
| 25 years | 41.7 mm (1.6 in) | |
| 50 years | 47.6 mm (1.9 in) | |
| 100 years | 53.9 mm (2.1 in) | Longer than the 73 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, 73 years of values from 1934 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: 59.2 mm (2.3 in) in 2023; 49.3 mm (1.9 in) in 2014; 49.3 mm (1.9 in) in 2021.

Climate Twins
2008 to 2023 against 1961 to 1990Over 2008 to 2023, Kemmerer 2N had a mean temperature of 3.8 C (38.8 F) and 270.0 mm (10.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Lima (United States, 355 km away), Lake George 8 SW (United States, 537 km away) and Butte Bert Mooney AP (United States, 487 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Lima | United States | 355 km (221 mi) | 4.1 C (39.3 F) | 306.7 mm (12.1 in) | 0.86 |
| Lake George 8 SW | United States | 537 km (334 mi) | 3.4 C (38.0 F) | 323.9 mm (12.8 in) | 0.90 |
| Butte Bert Mooney AP | United States | 487 km (303 mi) | 3.9 C (39.1 F) | 309.3 mm (12.2 in) | 0.92 |
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.
