The annual mean temperature here has risen by 0.2 C (0.1 to 0.2) per decade over 1895 to 2020. In Fahrenheit: 0.3 F (0.2 to 0.4) per decade. The slope is a straight line fitted to 85 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1895 to 2020 | 85 | Rise |
| Mean daily maximum | 0.12 C (0.04 to 0.20) per decade | 0.2 F (0.1 to 0.4) per decade | 1895 to 2020 | 85 | Rise |
| Mean daily minimum | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1895 to 2020 | 85 | Rise |
A year is complete when all 12 months have at least 20 days of both daily maximum and daily minimum readings. The annual mean is the mean of the monthly means. The trend describes this one station over this period; it does not say what caused the change.

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
85 years with a frostAcross 85 years with a frost, the median last spring frost at Sundance falls on 25 May and the median first autumn frost on 18 September, which leaves a median of 118 days between them.
In 1980 to 2020 the median growing season was 125 days. That is 15 days more than in 1895 to 1953.
Fitted over all years, the growing season changes by +1.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1895 to 1953) | Recent period (1980 to 2020) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 25 May | 30 May | 20 May | 10 days earlier | -1.0 days per decade |
| First autumn frost | 18 September | 16 September | 21 September | 5 days later | +0.3 days per decade |
| Growing days | 118 days | 110 days | 125 days | 15 days more | +1.3 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
94 years, 1897 to 2020A day with at least 36.0 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 80.3 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 | 36.0 mm (1.4 in) | |
| 5 years | 47.8 mm (1.9 in) | |
| 10 years | 55.7 mm (2.2 in) | |
| 25 years | 65.6 mm (2.6 in) | |
| 50 years | 73.0 mm (2.9 in) | |
| 100 years | 80.3 mm (3.2 in) | Longer than the 94 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, 94 years of values from 1897 to 2020.
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: 82.6 mm (3.3 in) in 1994; 71.1 mm (2.8 in) in 1964; 69.1 mm (2.7 in) in 1991.
Station Changes
No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
1995 to 2020 against 1961 to 1990Over 1995 to 2020, Sundance had a mean temperature of 7.0 C (44.5 F) and 527.5 mm (20.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Harrison (United States, 196 km away), Black Mtn (United States, 283 km away) and Gillette 18 SW (United States, 114 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Harrison | United States | 196 km (122 mi) | 6.7 C (44.1 F) | 426.9 mm (16.8 in) | 1.04 |
| Black Mtn | United States | 283 km (176 mi) | 7.4 C (45.2 F) | 337.9 mm (13.3 in) | 1.23 |
| Gillette 18 SW | United States | 114 km (71 mi) | 6.7 C (44.0 F) | 434.1 mm (17.1 in) | 1.26 |
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.
