The annual mean temperature here has fallen by 0.13 C (0.05 to 0.20) per decade over 1924 to 2022. In Fahrenheit: 0.2 F (0.1 to 0.4) per decade. The slope is a straight line fitted to 88 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | -0.13 C (-0.20 to -0.05) per decade | -0.2 F (-0.4 to -0.1) per decade | 1924 to 2022 | 88 | Fall |
| Mean daily maximum | -0.2 C (-0.3 to -0.1) per decade | -0.4 F (-0.6 to -0.3) per decade | 1924 to 2022 | 88 | Fall |
| Mean daily minimum | -0.02 C (-0.09 to 0.06) per decade | -0.03 F (-0.17 to 0.10) per decade | 1924 to 2022 | 88 | 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
88 years with a frostAcross 88 years with a frost, the median last spring frost at Trident falls on 15 May and the median first autumn frost on 19 September, which leaves a median of 125 days between them.
In 1983 to 2022 the median growing season was 125 days. That is 3 days fewer than in 1924 to 1953.
Fitted over all years, the growing season changes by +0.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1924 to 1953) | Recent period (1983 to 2022) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 May | 15 May | 15 May | no change | +0.2 days per decade |
| First autumn frost | 19 September | 19 September | 20 September | 1 day later | +0.3 days per decade |
| Growing days | 125 days | 128 days | 125 days | 3 days fewer | +0.1 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
78 years, 1938 to 2022A day with at least 25.4 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 58.3 mm (2.3 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 25.4 mm (1.0 in) | |
| 5 years | 33.6 mm (1.3 in) | |
| 10 years | 39.3 mm (1.5 in) | |
| 25 years | 46.7 mm (1.8 in) | |
| 50 years | 52.4 mm (2.1 in) | |
| 100 years | 58.3 mm (2.3 in) | Longer than the 78 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, 78 years of values from 1938 to 2022.
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: 56.1 mm (2.2 in) in 2005; 50.8 mm (2.0 in) in 1980; 43.2 mm (1.7 in) in 1977.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Trident, at 1992. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 0.3 C (0.6 F) lower than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1992 | -0.3 | -0.6 | 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
1998 to 2022 against 1961 to 1990Over 1998 to 2022, Trident had a mean temperature of 7.5 C (45.6 F) and 306.8 mm (12.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Richfield (United States, 386 km away), Black Mtn (United States, 390 km away) and Sybille Rsch Unit (United States, 675 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Richfield | United States | 386 km (240 mi) | 7.5 C (45.4 F) | 298.1 mm (11.7 in) | 0.82 |
| Black Mtn | United States | 390 km (242 mi) | 7.4 C (45.2 F) | 337.9 mm (13.3 in) | 0.84 |
| Sybille Rsch Unit | United States | 675 km (419 mi) | 7.8 C (46.0 F) | 406.3 mm (16.0 in) | 0.84 |
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.
