The annual mean temperature here has fallen by 0.1 C (0.1 to 0.2) per decade over 1923 to 2022. In Fahrenheit: 0.2 F (0.1 to 0.3) 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 | -0.1 C (-0.2 to -0.1) per decade | -0.2 F (-0.3 to -0.1) per decade | 1923 to 2022 | 88 | Fall |
| Mean daily maximum | -0.11 C (-0.19 to -0.03) per decade | -0.19 F (-0.34 to -0.05) per decade | 1923 to 2022 | 88 | Fall |
| Mean daily minimum | -0.1 C (-0.2 to -0.1) per decade | -0.2 F (-0.4 to -0.1) per decade | 1923 to 2022 | 88 | Fall |
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 Oakley 4W falls on 30 April and the median first autumn frost on 13 October, which leaves a median of 165 days between them.
In 1990 to 2022 the median growing season was 163 days. That is 3 days more than in 1923 to 1956.
Fitted over all years, the growing season changes by +0.1 days per decade at this station.
| Measure | Median, all years | Earliest period (1923 to 1956) | Recent period (1990 to 2022) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 30 April | 5 May | 3 May | 2 days earlier | -0.1 days per decade |
| First autumn frost | 13 October | 14 October | 12 October | 2 days earlier | 0.0 days per decade |
| Growing days | 165 days | 160 days | 163 days | 3 days more | +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
99 years, 1921 to 2025A day with at least 52.3 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 125.9 mm (5.0 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 52.3 mm (2.1 in) | |
| 5 years | 70.7 mm (2.8 in) | |
| 10 years | 83.3 mm (3.3 in) | |
| 25 years | 100.0 mm (3.9 in) | |
| 50 years | 112.8 mm (4.4 in) | |
| 100 years | 125.9 mm (5.0 in) | Longer than the 99 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, 99 years of values from 1921 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: 122.2 mm (4.8 in) in 2009; 114.8 mm (4.5 in) in 1942; 97.8 mm (3.9 in) in 1930.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Oakley 4W, at 1985. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1985 ran 0.3 C (0.5 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1985 | -0.2 | -0.4 | 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
2008 to 2022 against 1961 to 1990Over 2008 to 2022, Oakley 4W had a mean temperature of 11.0 C (51.7 F) and 522.2 mm (20.6 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Mc Cook (United States, 127 km away), Saint Francis (United States, 104 km away) and Imperial (United States, 167 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Mc Cook | United States | 127 km (79 mi) | 11.0 C (51.8 F) | 513.3 mm (20.2 in) | 0.99 |
| Saint Francis | United States | 104 km (65 mi) | 11.3 C (52.3 F) | 449.0 mm (17.7 in) | 0.99 |
| Imperial | United States | 167 km (104 mi) | 10.6 C (51.1 F) | 488.9 mm (19.2 in) | 1.01 |
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.
