The annual mean temperature here has risen by 0.2 C (0.1 to 0.2) per decade over 1934 to 2025. In Fahrenheit: 0.3 F (0.2 to 0.4) per decade. The slope is a straight line fitted to 81 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.2 C (0.1 to 0.2) per decade | 0.3 F (0.2 to 0.4) per decade | 1934 to 2025 | 81 | Rise |
| Mean daily maximum | 0.1 C (0.1 to 0.2) per decade | 0.2 F (0.1 to 0.4) per decade | 1934 to 2025 | 81 | Rise |
| Mean daily minimum | 0.2 C (0.2 to 0.3) per decade | 0.4 F (0.3 to 0.6) per decade | 1934 to 2025 | 81 | 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
81 years with a frostAcross 81 years with a frost, the median last spring frost at Walkerton 2 NW falls on 17 April and the median first autumn frost on 21 October, which leaves a median of 192 days between them.
In 1988 to 2025 the median growing season was 200 days. That is 13 days more than in 1934 to 1965.
Fitted over all years, the growing season changes by +3.2 days per decade at this station.
| Measure | Median, all years | Earliest period (1934 to 1965) | Recent period (1988 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 17 April | 17 April | 10 April | 7 days earlier | -1.1 days per decade |
| First autumn frost | 21 October | 20 October | 30 October | 10 days later | +2.1 days per decade |
| Growing days | 192 days | 187 days | 200 days | 13 days more | +3.2 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
92 years, 1933 to 2025A day with at least 66.9 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 196.6 mm (7.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 66.9 mm (2.6 in) | |
| 5 years | 92.0 mm (3.6 in) | |
| 10 years | 111.8 mm (4.4 in) | |
| 25 years | 141.5 mm (5.6 in) | |
| 50 years | 167.3 mm (6.6 in) | |
| 100 years | 196.6 mm (7.7 in) | Longer than the 92 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, 92 years of values from 1933 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: 223.3 mm (8.8 in) in 1935; 205.7 mm (8.1 in) in 1955; 196.9 mm (7.8 in) in 1999.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Walkerton 2 NW, at 2021. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2021 ran 0.3 C (0.5 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 2021 | +0.3 | +0.5 | 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 2025 against 1961 to 1990Over 2005 to 2025, Walkerton 2 NW had a mean temperature of 15.7 C (60.2 F) and 1,223.4 mm (48.2 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Cheraw (United States, 423 km away), Laurens (United States, 575 km away) and Hamlet (United States, 397 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Cheraw | United States | 423 km (263 mi) | 15.8 C (60.4 F) | 1,184.8 mm (46.6 in) | 0.51 |
| Laurens | United States | 575 km (357 mi) | 15.6 C (60.2 F) | 1,191.8 mm (46.9 in) | 0.51 |
| Hamlet | United States | 397 km (247 mi) | 15.9 C (60.5 F) | 1,221.0 mm (48.1 in) | 0.56 |
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.
