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

68 years with a frost

Across 68 years with a frost, the median last spring frost at Hudson falls on 14 April and the median first autumn frost on 25 October, which leaves a median of 195 days between them.

In 1991 to 2022 the median growing season was 190 days. That is 5 days fewer than in 1951 to 1982.

Fitted over all years, the growing season changes by +0.7 days per decade at this station.

Frost dates and growing season at Hudson
Measure	Median, all years	Earliest period (1951 to 1982)	Recent period (1991 to 2022)	Recent against earliest	Fitted trend
Last spring frost	14 April	13 April	14 April	1 day later	-0.8 days per decade
First autumn frost	25 October	26 October	24 October	2 days earlier	-0.1 days per decade
Growing days	195 days	195 days	190 days	5 days fewer	+0.7 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, 1923 to 2024

A day with at least 57.3 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 150.5 mm (5.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Hudson: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	57.3 mm (2.3 in)
5 years	78.3 mm (3.1 in)
10 years	93.7 mm (3.7 in)
25 years	115.0 mm (4.5 in)
50 years	132.2 mm (5.2 in)
100 years	150.5 mm (5.9 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 1923 to 2024.

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: 197.4 mm (7.8 in) in 1973; 128.5 mm (5.1 in) in 1993; 114.3 mm (4.5 in) in 2002.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Hudson, at 1984 and 2012. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1984 ran 0.2 C (0.4 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2012 ran 0.6 C (1.2 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Hudson, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1984	+0.2	+0.4	likely	5
2012	-0.6	-1.2	likely	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.

Climate Twins

2006 to 2022 against 1961 to 1990

Over 2006 to 2022, Hudson had a mean temperature of 14.0 C (57.1 F) and 712.2 mm (28.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Helena 1 SSE (United States, 178 km away), Norwich (United States, 101 km away) and Mutual (United States, 213 km away).

Climate twins of Hudson: stations whose 1961 to 1990 climate is closest to its 2006 to 2022 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Helena 1 SSE	United States	178 km (111 mi)	14.2 C (57.5 F)	702.7 mm (27.7 in)	0.75
Norwich	United States	101 km (63 mi)	14.1 C (57.3 F)	725.5 mm (28.6 in)	0.76
Mutual	United States	213 km (132 mi)	14.4 C (57.9 F)	640.4 mm (25.2 in)	0.88

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.
