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
70 years with a frostAcross 70 years with a frost, the median last spring frost at Marion Forks Fish Hatchery falls on 22 May and the median first autumn frost on 26 September, which leaves a median of 127 days between them.
In 1995 to 2025 the median growing season was 144 days. That is 22 days more than in 1949 to 1982.
Fitted over all years, the growing season changes by +3.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1949 to 1982) | Recent period (1995 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 22 May | 30 May | 15 May | 15 days earlier | -1.8 days per decade |
| First autumn frost | 26 September | 23 September | 2 October | 9 days later | +1.3 days per decade |
| Growing days | 127 days | 122 days | 144 days | 22 days more | +3.1 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
71 years, 1955 to 2025A day with at least 75.7 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 162.8 mm (6.4 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 75.7 mm (3.0 in) | |
| 5 years | 97.4 mm (3.8 in) | |
| 10 years | 112.4 mm (4.4 in) | |
| 25 years | 132.1 mm (5.2 in) | |
| 50 years | 147.3 mm (5.8 in) | |
| 100 years | 162.8 mm (6.4 in) | Longer than the 71 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, 71 years of values from 1955 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: 148.1 mm (5.8 in) in 1964; 147.3 mm (5.8 in) in 1998; 147.3 mm (5.8 in) in 2025.

Climate Twins
2010 to 2025 against 1961 to 1990Over 2010 to 2025, Marion Forks Fish Hatchery had a mean temperature of 8.6 C (47.5 F) and 1,792.3 mm (70.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Lake Spaulding (United States, 599 km away), Diablo Dam (United States, 460 km away) and Postojna (Slovenia, 9,077 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Lake Spaulding | United States | 599 km (372 mi) | 8.8 C (47.8 F) | 1,745.1 mm (68.7 in) | 0.85 |
| Diablo Dam | United States | 460 km (286 mi) | 9.2 C (48.5 F) | 2,025.2 mm (79.7 in) | 1.29 |
| Postojna | Slovenia | 9,077 km (5,640 mi) | 8.6 C (47.6 F) | 1,571.6 mm (61.9 in) | 1.34 |
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.
