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 Cottonwood Weir falls on 30 April and the median first autumn frost on 21 October, which leaves a median of 169 days between them.
In 1993 to 2025 the median growing season was 176 days. That is 13 days more than in 1942 to 1977.
Fitted over all years, the growing season changes by +1.9 days per decade at this station.
| Measure | Median, all years | Earliest period (1942 to 1977) | Recent period (1993 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 30 April | 4 May | 27 April | 7 days earlier | -0.7 days per decade |
| First autumn frost | 21 October | 18 October | 23 October | 5 days later | +1.1 days per decade |
| Growing days | 169 days | 163 days | 176 days | 13 days more | +1.9 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
92 years, 1918 to 2025A day with at least 37.3 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 81.7 mm (3.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 37.3 mm (1.5 in) | |
| 5 years | 48.0 mm (1.9 in) | |
| 10 years | 55.5 mm (2.2 in) | |
| 25 years | 65.6 mm (2.6 in) | |
| 50 years | 73.5 mm (2.9 in) | |
| 100 years | 81.7 mm (3.2 in) | Longer than the 92 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, 92 years of values from 1918 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: 118.1 mm (4.6 in) in 1982; 81.3 mm (3.2 in) in 1953; 66.3 mm (2.6 in) in 1968.

Climate Twins
2010 to 2025 against 1961 to 1990Over 2010 to 2025, Cottonwood Weir had a mean temperature of 12.3 C (54.1 F) and 567.2 mm (22.3 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Brownlee Dam (United States, 628 km away), Sharon Springs (United States, 878 km away) and Scott City (United States, 961 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Brownlee Dam | United States | 628 km (390 mi) | 12.0 C (53.7 F) | 435.9 mm (17.2 in) | 0.91 |
| Sharon Springs | United States | 878 km (546 mi) | 12.5 C (54.4 F) | 485.6 mm (19.1 in) | 1.14 |
| Scott City | United States | 961 km (597 mi) | 12.3 C (54.1 F) | 515.9 mm (20.3 in) | 1.16 |
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.
