The annual mean temperature here has risen by 0.06 C (0.00 to 0.12) per decade over 1900 to 2024. In Fahrenheit: 0.11 F (0.01 to 0.22) per decade. The slope is a straight line fitted to 98 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.06 C (0.00 to 0.12) per decade | 0.11 F (0.01 to 0.22) per decade | 1900 to 2024 | 98 | Rise |
| Mean daily maximum | -0.02 C (-0.09 to 0.05) per decade | -0.03 F (-0.16 to 0.10) per decade | 1900 to 2024 | 98 | Not clearly different from zero |
| Mean daily minimum | 0.1 C (0.1 to 0.2) per decade | 0.3 F (0.1 to 0.4) per decade | 1900 to 2024 | 98 | 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
98 years with a frostAcross 98 years with a frost, the median last spring frost at Basin falls on 11 May and the median first autumn frost on 22 September, which leaves a median of 134 days between them.
In 1994 to 2024 the median growing season was 141 days. That is 9 days more than in 1900 to 1953.
Fitted over all years, the growing season changes by +1.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1900 to 1953) | Recent period (1994 to 2024) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 11 May | 14 May | 11 May | 3 days earlier | -0.7 days per decade |
| First autumn frost | 22 September | 21 September | 3 October | 12 days later | +0.8 days per decade |
| Growing days | 134 days | 132 days | 141 days | 9 days more | +1.5 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
93 years, 1899 to 2024A day with at least 19.6 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 44.5 mm (1.8 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 19.6 mm (0.8 in) | |
| 5 years | 26.5 mm (1.0 in) | |
| 10 years | 30.9 mm (1.2 in) | |
| 25 years | 36.5 mm (1.4 in) | |
| 50 years | 40.5 mm (1.6 in) | |
| 100 years | 44.5 mm (1.8 in) | Longer than the 93 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, 93 years of values from 1899 to 2024.
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: 50.8 mm (2.0 in) in 1988; 38.9 mm (1.5 in) in 2011; 36.8 mm (1.4 in) in 1989.
Station Changes
3 suspected3 changes were suspected in the annual mean temperature of Basin, at 1973, 1994 and 2015. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1973 ran 0.6 C (1.0 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1994 ran 0.3 C (0.5 F) higher than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2015 ran 0.6 C (1.0 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1973 | -0.6 | -1.0 | likely | 5 |
| 1994 | +0.3 | +0.5 | possible | 5 |
| 2015 | +0.6 | +1.0 | likely | 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
2010 to 2024 against 1961 to 1990Over 2010 to 2024, Basin had a mean temperature of 8.6 C (47.5 F) and 190.7 mm (7.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Bonanza (United States, 494 km away), Boysen Dam (United States, 109 km away) and Dinosaur Nm-Quarry Area (United States, 451 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Bonanza | United States | 494 km (307 mi) | 8.8 C (47.9 F) | 230.0 mm (9.1 in) | 0.80 |
| Boysen Dam | United States | 109 km (68 mi) | 8.7 C (47.6 F) | 233.0 mm (9.2 in) | 0.85 |
| Dinosaur Nm-Quarry Area | United States | 451 km (280 mi) | 8.6 C (47.4 F) | 212.7 mm (8.4 in) | 0.98 |
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.
