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
66 years with a frostAcross 66 years with a frost, the median last spring frost at Terry falls on 15 May and the median first autumn frost on 20 September, which leaves a median of 129 days between them.
In 1990 to 2025 the median growing season was 134 days. That is 5 days more than in 1950 to 1981.
Fitted over all years, the growing season changes by +2.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1950 to 1981) | Recent period (1990 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 May | 14 May | 15 May | 1 day later | -0.2 days per decade |
| First autumn frost | 20 September | 17 September | 26 September | 9 days later | +1.9 days per decade |
| Growing days | 129 days | 129 days | 134 days | 5 days more | +2.1 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
56 years, 1950 to 2025A day with at least 37.5 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 83.2 mm (3.3 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 37.5 mm (1.5 in) | |
| 5 years | 50.8 mm (2.0 in) | |
| 10 years | 59.2 mm (2.3 in) | |
| 25 years | 69.3 mm (2.7 in) | |
| 50 years | 76.4 mm (3.0 in) | |
| 100 years | 83.2 mm (3.3 in) | Longer than the 56 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, 56 years of values from 1950 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: 98.6 mm (3.9 in) in 2015; 74.4 mm (2.9 in) in 2006; 64.8 mm (2.6 in) in 1973.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Terry, at 1978 and 1994. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 0.5 C (0.8 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1994 ran 0.7 C (1.3 F) higher than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1978 | -0.4 | -0.8 | likely | 5 |
| 1994 | +0.7 | +1.3 | 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 2025 against 1961 to 1990Over 2010 to 2025, Terry had a mean temperature of 7.6 C (45.8 F) and 313.9 mm (12.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Powderville 8 NNE (United States, 107 km away), Maurine 12SW (United States, 302 km away) and Faith (United States, 320 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Powderville 8 NNE | United States | 107 km (66 mi) | 7.7 C (45.8 F) | 330.5 mm (13.0 in) | 0.92 |
| Maurine 12SW | United States | 302 km (188 mi) | 7.3 C (45.2 F) | 416.4 mm (16.4 in) | 0.94 |
| Faith | United States | 320 km (199 mi) | 7.5 C (45.5 F) | 422.7 mm (16.6 in) | 1.00 |
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.
