The fitted trend in annual mean temperature here over 1909 to 2021 is 0.00 C (-0.06 to 0.07) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.00 F (-0.11 to 0.12) per decade. The slope is a straight line fitted to 97 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.00 C (-0.06 to 0.07) per decade | 0.00 F (-0.11 to 0.12) per decade | 1909 to 2021 | 97 | Not clearly different from zero |
| Mean daily maximum | -0.08 C (-0.16 to 0.00) per decade | -0.15 F (-0.28 to -0.01) per decade | 1909 to 2021 | 97 | Fall |
| Mean daily minimum | 0.09 C (0.02 to 0.15) per decade | 0.15 F (0.04 to 0.27) per decade | 1909 to 2021 | 97 | 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
97 years with a frostAcross 97 years with a frost, the median last spring frost at Butte falls on 7 May and the median first autumn frost on 3 October, which leaves a median of 150 days between them.
In 1990 to 2021 the median growing season was 155 days. That is 9 days more than in 1909 to 1949.
Fitted over all years, the growing season changes by +1.7 days per decade at this station.
| Measure | Median, all years | Earliest period (1909 to 1949) | Recent period (1990 to 2021) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 7 May | 8 May | 8 May | no change | -0.5 days per decade |
| First autumn frost | 3 October | 26 September | 8 October | 12 days later | +1.1 days per decade |
| Growing days | 150 days | 146 days | 155 days | 9 days more | +1.7 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
103 years, 1907 to 2021A day with at least 53.8 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 115.9 mm (4.6 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 53.8 mm (2.1 in) | |
| 5 years | 70.6 mm (2.8 in) | |
| 10 years | 81.7 mm (3.2 in) | |
| 25 years | 95.5 mm (3.8 in) | |
| 50 years | 105.8 mm (4.2 in) | |
| 100 years | 115.9 mm (4.6 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 103 years of values from 1907 to 2021.
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: 126.2 mm (5.0 in) in 2008; 101.6 mm (4.0 in) in 1932; 100.8 mm (4.0 in) in 1963.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Butte, at 1979 and 1999. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1979 ran 0.3 C (0.5 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1999 ran 0.6 C (1.1 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1979 | +0.3 | +0.5 | likely | 5 |
| 1999 | -0.6 | -1.1 | 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
2005 to 2021 against 1961 to 1990Over 2005 to 2021, Butte had a mean temperature of 8.9 C (48.0 F) and 709.7 mm (27.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Albion (United States, 153 km away), Mt Mary College (United States, 880 km away) and Oakdale (United States, 119 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Albion | United States | 153 km (95 mi) | 8.9 C (48.0 F) | 699.4 mm (27.5 in) | 0.90 |
| Mt Mary College | United States | 880 km (547 mi) | 9.0 C (48.2 F) | 787.2 mm (31.0 in) | 0.95 |
| Oakdale | United States | 119 km (74 mi) | 8.8 C (47.9 F) | 639.1 mm (25.2 in) | 1.02 |
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.
