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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Middleton falls on 27 April and the median first autumn frost on 11 October, which leaves a median of 169 days between them.

In 1995 to 2025 the median growing season was 174 days. That is 4 days more than in 1936 to 1967.

Fitted over all years, the growing season changes by +0.1 days per decade at this station.

Frost dates and growing season at Middleton
Measure	Median, all years	Earliest period (1936 to 1967)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	27 April	25 April	25 April	no change	+0.9 days per decade
First autumn frost	11 October	10 October	17 October	7 days later	+1.0 days per decade
Growing days	169 days	170 days	174 days	4 days more	+0.1 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, 1926 to 2025

A day with at least 67.8 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 185.2 mm (7.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Middleton: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	67.8 mm (2.7 in)
5 years	91.5 mm (3.6 in)
10 years	109.9 mm (4.3 in)
25 years	136.8 mm (5.4 in)
50 years	159.6 mm (6.3 in)
100 years	185.2 mm (7.3 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 1926 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: 219.5 mm (8.6 in) in 1962; 166.4 mm (6.6 in) in 1996; 164.3 mm (6.5 in) in 2006.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Middleton had a mean temperature of 10.4 C (50.7 F) and 1,203.6 mm (47.4 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Westchester Co AP (United States, 280 km away), Providence (United States, 103 km away) and Wanaque Raymond Dam (United States, 322 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Westchester Co AP	United States	280 km (174 mi)	10.4 C (50.7 F)	1,240.5 mm (48.8 in)	0.47
Providence	United States	103 km (64 mi)	10.3 C (50.5 F)	1,158.6 mm (45.6 in)	0.51
Wanaque Raymond Dam	United States	322 km (200 mi)	10.3 C (50.6 F)	1,192.3 mm (46.9 in)	0.54

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.
