The fitted trend in annual mean temperature here over 1894 to 2020 is 0.00 C (-0.05 to 0.05) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.0 F (-0.1 to 0.1) per decade. The slope is a straight line fitted to 93 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.00 C (-0.05 to 0.05) per decade | 0.0 F (-0.1 to 0.1) per decade | 1894 to 2020 | 93 | Not clearly different from zero |
| Mean daily maximum | -0.03 C (-0.09 to 0.03) per decade | -0.1 F (-0.2 to 0.1) per decade | 1894 to 2020 | 93 | Not clearly different from zero |
| Mean daily minimum | 0.03 C (-0.02 to 0.08) per decade | 0.05 F (-0.04 to 0.14) per decade | 1894 to 2020 | 93 | 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
93 years with a frostAcross 93 years with a frost, the median last spring frost at Warrenton 1 N falls on 15 April and the median first autumn frost on 20 October, which leaves a median of 188 days between them.
In 1959 to 2020 the median growing season was 182 days. That is 8 days fewer than in 1894 to 1923.
Fitted over all years, the growing season changes by -0.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1894 to 1923) | Recent period (1959 to 2020) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 April | 14 April | 15 April | 1 day later | 0.0 days per decade |
| First autumn frost | 20 October | 21 October | 17 October | 4 days earlier | -0.5 days per decade |
| Growing days | 188 days | 190 days | 182 days | 8 days fewer | -0.5 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
100 years, 1894 to 2020A day with at least 64.6 mm (2.5 in) of rain is expected about once in 2 years. A day with at least 163.2 mm (6.4 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 64.6 mm (2.5 in) | |
| 5 years | 84.8 mm (3.3 in) | |
| 10 years | 100.3 mm (3.9 in) | |
| 25 years | 122.8 mm (4.8 in) | |
| 50 years | 141.9 mm (5.6 in) | |
| 100 years | 163.2 mm (6.4 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 100 years of values from 1894 to 2020.
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: 149.9 mm (5.9 in) in 1905; 148.6 mm (5.9 in) in 1980; 140.0 mm (5.5 in) in 1946.

2 suspected2 changes were suspected in the annual mean temperature of Warrenton 1 N, at 1920 and 1939. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1920 ran 0.7 C (1.2 F) higher than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1939 ran 0.3 C (0.5 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1920 | +0.7 | +1.2 | likely | 5 |
| 1939 | -0.3 | -0.5 | 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.
