The annual mean temperature here has risen by 0.05 C (0.00 to 0.10) per decade over 1876 to 1983. In Fahrenheit: 0.09 F (0.01 to 0.18) per decade. The slope is a straight line fitted to 97 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.05 C (0.00 to 0.10) per decade | 0.09 F (0.01 to 0.18) per decade | 1876 to 1983 | 97 | Rise |
| Mean daily maximum | 0.07 C (0.01 to 0.12) per decade | 0.12 F (0.01 to 0.22) per decade | 1876 to 1983 | 97 | Rise |
| Mean daily minimum | 0.04 C (-0.02 to 0.09) per decade | 0.07 F (-0.03 to 0.17) per decade | 1876 to 1983 | 97 | 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
97 years with a frostAcross 97 years with a frost, the median last spring frost at Port Dover falls on 8 May and the median first autumn frost on 10 October, which leaves a median of 157 days between them.
In 1954 to 1983 the median growing season was 159 days. That is 2 days more than in 1876 to 1905.
Fitted over all years, the growing season changes by -0.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1876 to 1905) | Recent period (1954 to 1983) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 8 May | 4 May | 8 May | 4 days later | +0.2 days per decade |
| First autumn frost | 10 October | 11 October | 13 October | 2 days later | -0.3 days per decade |
| Growing days | 157 days | 157 days | 159 days | 2 days more | -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
96 years, 1874 to 1983A day with at least 46.8 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 107.3 mm (4.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 46.8 mm (1.8 in) | |
| 5 years | 62.1 mm (2.4 in) | |
| 10 years | 72.5 mm (2.9 in) | |
| 25 years | 86.2 mm (3.4 in) | |
| 50 years | 96.7 mm (3.8 in) | |
| 100 years | 107.3 mm (4.2 in) | Longer than the 96 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, 96 years of values from 1874 to 1983.
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: 99.3 mm (3.9 in) in 1945; 97.3 mm (3.8 in) in 1968; 94.7 mm (3.7 in) in 1954.
