The fitted trend in annual mean temperature here over 1894 to 2016 is -0.02 C (-0.06 to 0.02) per decade. The interval includes zero, so the trend is not clearly different from zero. In Fahrenheit: -0.03 F (-0.11 to 0.04) per decade. The slope is a straight line fitted to 96 complete years; the brackets give its 95 percent interval.
| Measure | Per decade (C) | Per decade (F) | Period | Complete years | Reading |
|---|---|---|---|---|---|
| Annual mean temperature | -0.02 C (-0.06 to 0.02) per decade | -0.03 F (-0.11 to 0.04) per decade | 1894 to 2016 | 96 | Not clearly different from zero |
| Mean daily maximum | 0.1 C (0.1 to 0.2) per decade | 0.2 F (0.1 to 0.3) per decade | 1894 to 2016 | 96 | Rise |
| Mean daily minimum | -0.2 C (-0.2 to -0.1) per decade | -0.3 F (-0.4 to -0.2) per decade | 1894 to 2016 | 96 | 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
96 years with a frostAcross 96 years with a frost, the median last spring frost at W Chester 2 NW falls on 20 April and the median first autumn frost on 20 October, which leaves a median of 184 days between them.
In 1976 to 2016 the median growing season was 173 days. That is 20 days fewer than in 1894 to 1931.
Fitted over all years, the growing season changes by -2.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1894 to 1931) | Recent period (1976 to 2016) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 20 April | 12 April | 26 April | 14 days later | +1.5 days per decade |
| First autumn frost | 20 October | 26 October | 17 October | 9 days earlier | -1.1 days per decade |
| Growing days | 184 days | 193 days | 173 days | 20 days fewer | -2.5 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
101 years, 1896 to 2016A day with at least 73.6 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 191.1 mm (7.5 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 73.6 mm (2.9 in) | |
| 5 years | 100.0 mm (3.9 in) | |
| 10 years | 119.4 mm (4.7 in) | |
| 25 years | 146.2 mm (5.8 in) | |
| 50 years | 167.9 mm (6.6 in) | |
| 100 years | 191.1 mm (7.5 in) |
The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 101 years of values from 1896 to 2016.
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: 226.3 mm (8.9 in) in 2004; 189.5 mm (7.5 in) in 2011; 150.9 mm (5.9 in) in 1950.

No change in the annual mean temperature of this station was found against its neighbours.
Climate Twins
2002 to 2016 against 1961 to 1990Over 2002 to 2016, W Chester 2 NW had a mean temperature of 11.6 C (52.8 F) and 1,342.0 mm (52.8 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Dobbs Ferry-Ardsley (United States, 191 km away), Cranford (United States, 135 km away) and Little Falls (United States, 157 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Dobbs Ferry-Ardsley | United States | 191 km (119 mi) | 11.7 C (53.1 F) | 1,279.4 mm (50.4 in) | 0.52 |
| Cranford | United States | 135 km (84 mi) | 11.7 C (53.0 F) | 1,344.2 mm (52.9 in) | 0.54 |
| Little Falls | United States | 157 km (98 mi) | 11.2 C (52.1 F) | 1,282.8 mm (50.5 in) | 0.57 |
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.
