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
65 years with a frostAcross 65 years with a frost, the median last spring frost at Stampede Pass falls on 30 May and the median first autumn frost on 3 October, which leaves a median of 122 days between them.
In 1979 to 2025 the median growing season was 126 days. That is 3 days more than in 1944 to 1973.
Fitted over all years, the growing season changes by +4.8 days per decade at this station.
| Measure | Median, all years | Earliest period (1944 to 1973) | Recent period (1979 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 30 May | 30 May | 31 May | 1 day later | -2.0 days per decade |
| First autumn frost | 3 October | 3 October | 5 October | 2 days later | +2.7 days per decade |
| Growing days | 122 days | 123 days | 126 days | 3 days more | +4.8 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
64 years, 1944 to 2023A day with at least 85.9 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 296.6 mm (11.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 85.9 mm (3.4 in) | |
| 5 years | 122.5 mm (4.8 in) | |
| 10 years | 153.1 mm (6.0 in) | |
| 25 years | 201.1 mm (7.9 in) | |
| 50 years | 244.8 mm (9.6 in) | |
| 100 years | 296.6 mm (11.7 in) | Longer than the 64 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, 64 years of values from 1944 to 2023.
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: 304.8 mm (12.0 in) in 2010; 208.8 mm (8.2 in) in 2006; 198.4 mm (7.8 in) in 2007.
