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

64 years with a frost

Across 64 years with a frost, the median last spring frost at Amity 4 NE falls on 18 April and the median first autumn frost on 18 October, which leaves a median of 181 days between them.

In 1992 to 2021 the median growing season was 189 days. That is 10 days more than in 1947 to 1985.

Fitted over all years, the growing season changes by +2.6 days per decade at this station.

Frost dates and growing season at Amity 4 NE
Measure	Median, all years	Earliest period (1947 to 1985)	Recent period (1992 to 2021)	Recent against earliest	Fitted trend
Last spring frost	18 April	23 April	12 April	11 days earlier	-2.6 days per decade
First autumn frost	18 October	20 October	20 October	no change	0.0 days per decade
Growing days	181 days	179 days	189 days	10 days more	+2.6 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

78 years, 1936 to 2021

A day with at least 74.2 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 217.3 mm (8.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Amity 4 NE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	74.2 mm (2.9 in)
5 years	105.3 mm (4.1 in)
10 years	128.5 mm (5.1 in)
25 years	161.2 mm (6.3 in)
50 years	188.1 mm (7.4 in)
100 years	217.3 mm (8.6 in)	Longer than the 78 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, 78 years of values from 1936 to 2021.

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: 205.2 mm (8.1 in) in 2021; 170.2 mm (6.7 in) in 1993; 165.6 mm (6.5 in) in 2011.

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

2007 to 2021 against 1961 to 1990

Over 2007 to 2021, Amity 4 NE had a mean temperature of 11.3 C (52.4 F) and 1,059.1 mm (41.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Mexico (United States, 228 km away), Quincy Rgnl AP (United States, 270 km away) and Havana (United States, 368 km away).

Climate twins of Amity 4 NE: stations whose 1961 to 1990 climate is closest to its 2007 to 2021 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Mexico	United States	228 km (142 mi)	11.3 C (52.3 F)	1,013.3 mm (39.9 in)	0.61
Quincy Rgnl AP	United States	270 km (168 mi)	11.2 C (52.1 F)	1,008.4 mm (39.7 in)	0.67
Havana	United States	368 km (229 mi)	11.3 C (52.3 F)	939.8 mm (37.0 in)	0.69

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.
