The annual mean temperature here has risen by 0.08 C (0.03 to 0.12) per decade over 1899 to 2010. In Fahrenheit: 0.1 F (0.1 to 0.2) per decade. The slope is a straight line fitted to 86 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | 0.08 C (0.03 to 0.12) per decade | 0.1 F (0.1 to 0.2) per decade | 1899 to 2010 | 86 | Rise |
| Mean daily maximum | 0.1 C (0.1 to 0.2) per decade | 0.2 F (0.1 to 0.3) per decade | 1899 to 2010 | 86 | Rise |
| Mean daily minimum | 0.02 C (-0.02 to 0.07) per decade | 0.04 F (-0.04 to 0.12) per decade | 1899 to 2010 | 86 | 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
86 years with a frostAcross 86 years with a frost, the median last spring frost at Chestertown falls on 9 April and the median first autumn frost on 1 November, which leaves a median of 207 days between them.
In 1981 to 2010 the median growing season was 208 days. That is 2 days more than in 1899 to 1954.
Fitted over all years, the growing season changes by +0.3 days per decade at this station.
| Measure | Median, all years | Earliest period (1899 to 1954) | Recent period (1981 to 2010) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 9 April | 11 April | 7 April | 4 days earlier | -0.4 days per decade |
| First autumn frost | 1 November | 1 November | 2 November | 1 day later | -0.1 days per decade |
| Growing days | 207 days | 206 days | 208 days | 2 days more | +0.3 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
88 years, 1896 to 2010A day with at least 65.8 mm (2.6 in) of rain is expected about once in 2 years. A day with at least 181.2 mm (7.1 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 65.8 mm (2.6 in) | |
| 5 years | 89.3 mm (3.5 in) | |
| 10 years | 107.4 mm (4.2 in) | |
| 25 years | 133.8 mm (5.3 in) | |
| 50 years | 156.2 mm (6.1 in) | |
| 100 years | 181.2 mm (7.1 in) | Longer than the 88 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, 88 years of values from 1896 to 2010.
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: 280.9 mm (11.1 in) in 1999; 159.5 mm (6.3 in) in 1972; 126.0 mm (5.0 in) in 1955.
