The fitted trend in annual mean temperature here over 1895 to 1998 is 0.04 C (-0.01 to 0.09) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: 0.07 F (-0.01 to 0.15) per decade. The slope is a straight line fitted to 95 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.04 C (-0.01 to 0.09) per decade | 0.07 F (-0.01 to 0.15) per decade | 1895 to 1998 | 95 | Not clearly different from zero |
| Mean daily maximum | 0.07 C (0.01 to 0.12) per decade | 0.12 F (0.02 to 0.21) per decade | 1895 to 1998 | 95 | Rise |
| Mean daily minimum | 0.01 C (-0.04 to 0.07) per decade | 0.03 F (-0.08 to 0.13) per decade | 1895 to 1998 | 95 | 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
95 years with a frostAcross 95 years with a frost, the median last spring frost at Woodstock falls on 23 April and the median first autumn frost on 13 October, which leaves a median of 170 days between them.
In 1961 to 1998 the median growing season was 174 days. That is 9 days fewer than in 1895 to 1924.
Fitted over all years, the growing season changes by -0.7 days per decade at this station.
| Measure | Median, all years | Earliest period (1895 to 1924) | Recent period (1961 to 1998) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 23 April | 16 April | 23 April | 7 days later | +0.4 days per decade |
| First autumn frost | 13 October | 13 October | 14 October | 1 day later | -0.3 days per decade |
| Growing days | 170 days | 183 days | 174 days | 9 days fewer | -0.7 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, 1895 to 1998A day with at least 68.2 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 149.7 mm (5.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 68.2 mm (2.7 in) | |
| 5 years | 88.6 mm (3.5 in) | |
| 10 years | 102.6 mm (4.0 in) | |
| 25 years | 121.0 mm (4.8 in) | |
| 50 years | 135.2 mm (5.3 in) | |
| 100 years | 149.7 mm (5.9 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 1895 to 1998.
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: 153.7 mm (6.1 in) in 1955; 127.8 mm (5.0 in) in 1911; 127.8 mm (5.0 in) in 1966.
Station Changes
1 suspectedOne change was suspected in the annual mean temperature of Woodstock, at 1980. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1980 ran 0.1 C (0.2 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1980 | +0.1 | +0.2 | 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.
