The fitted trend in annual mean temperature here over 1914 to 2024 is 0.04 C (-0.04 to 0.12) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.1 F (-0.1 to 0.2) per decade. The slope is a straight line fitted to 90 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.04 C (-0.04 to 0.12) per decade | 0.1 F (-0.1 to 0.2) per decade | 1914 to 2024 | 90 | Not clearly different from zero |
| Mean daily maximum | 0.00 C (-0.10 to 0.09) per decade | 0.00 F (-0.17 to 0.17) per decade | 1914 to 2024 | 90 | Not clearly different from zero |
| Mean daily minimum | 0.08 C (0.00 to 0.15) per decade | 0.14 F (-0.01 to 0.28) per decade | 1914 to 2024 | 90 | Not clearly different from zero |
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
90 years with a frostAcross 90 years with a frost, the median last spring frost at Winner falls on 6 May and the median first autumn frost on 4 October, which leaves a median of 150 days between them.
In 1989 to 2024 the median growing season was 160 days. That is 13 days more than in 1914 to 1958.
Fitted over all years, the growing season changes by +2.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1914 to 1958) | Recent period (1989 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 6 May | 8 May | 4 May | 4 days earlier | -0.8 days per decade |
| First autumn frost | 4 October | 30 September | 10 October | 10 days later | +1.6 days per decade |
| Growing days | 150 days | 147 days | 160 days | 13 days more | +2.4 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
95 years, 1925 to 2025A day with at least 50.9 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 131.5 mm (5.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 50.9 mm (2.0 in) | |
| 5 years | 69.3 mm (2.7 in) | |
| 10 years | 82.6 mm (3.3 in) | |
| 25 years | 100.9 mm (4.0 in) | |
| 50 years | 115.7 mm (4.6 in) | |
| 100 years | 131.5 mm (5.2 in) | Longer than the 95 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, 95 years of values from 1925 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: 127.0 mm (5.0 in) in 1977; 121.9 mm (4.8 in) in 2004; 110.5 mm (4.4 in) in 1958.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Winner, at 2018. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2018 ran 0.6 C (1.0 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 2018 | -0.6 | -1.0 | possible | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
Climate Twins
2007 to 2024 against 1961 to 1990Over 2007 to 2024, Winner had a mean temperature of 9.4 C (48.9 F) and 568.1 mm (22.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are N Platte Exp Farm (United States, 268 km away), Valentine Nwr (United States, 113 km away) and Purdum (United States, 149 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| N Platte Exp Farm | United States | 268 km (167 mi) | 9.3 C (48.7 F) | 485.7 mm (19.1 in) | 1.02 |
| Valentine Nwr | United States | 113 km (70 mi) | 9.5 C (49.0 F) | 546.6 mm (21.5 in) | 1.07 |
| Purdum | United States | 149 km (93 mi) | 9.2 C (48.6 F) | 549.8 mm (21.6 in) | 1.07 |
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.
