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

111 years with a frost

Across 111 years with a frost, the median last spring frost at Ashley falls on 17 May and the median first autumn frost on 20 September, which leaves a median of 125 days between them.

In 1995 to 2025 the median growing season was 144 days. That is 29 days more than in 1894 to 1933.

Fitted over all years, the growing season changes by +3.5 days per decade at this station.

Frost dates and growing season at Ashley
Measure	Median, all years	Earliest period (1894 to 1933)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	17 May	25 May	14 May	11 days earlier	-1.3 days per decade
First autumn frost	20 September	16 September	2 October	16 days later	+2.2 days per decade
Growing days	125 days	115 days	144 days	29 days more	+3.5 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

113 years, 1893 to 2025

A day with at least 45.7 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 100.6 mm (4.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Ashley: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	45.7 mm (1.8 in)
5 years	60.9 mm (2.4 in)
10 years	70.8 mm (2.8 in)
25 years	83.0 mm (3.3 in)
50 years	91.9 mm (3.6 in)
100 years	100.6 mm (4.0 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 113 years of values from 1893 to 2025.

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: 100.6 mm (4.0 in) in 1966; 94.0 mm (3.7 in) in 1964; 91.2 mm (3.6 in) in 1895.

Station Changes

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Ashley had a mean temperature of 5.5 C (42.0 F) and 481.9 mm (19.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are New Salem 5NW (United States, 188 km away), Underwood (United States, 207 km away) and Watertown Rgnl AP (United States, 215 km away).

Climate twins of Ashley: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
New Salem 5NW	United States	188 km (117 mi)	5.4 C (41.8 F)	438.3 mm (17.3 in)	1.21
Underwood	United States	207 km (129 mi)	5.2 C (41.4 F)	441.6 mm (17.4 in)	1.22
Watertown Rgnl AP	United States	215 km (134 mi)	6.0 C (42.7 F)	563.9 mm (22.2 in)	1.24

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.
