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

94 years with a frost

Across 94 years with a frost, the median last spring frost at Wilmington 3 N falls on 27 April and the median first autumn frost on 14 October, which leaves a median of 169 days between them.

In 1985 to 2017 the median growing season was 180 days. That is 16 days more than in 1918 to 1948.

Fitted over all years, the growing season changes by +2.8 days per decade at this station.

Frost dates and growing season at Wilmington 3 N
Measure	Median, all years	Earliest period (1918 to 1948)	Recent period (1985 to 2017)	Recent against earliest	Fitted trend
Last spring frost	27 April	29 April	16 April	13 days earlier	-1.7 days per decade
First autumn frost	14 October	13 October	18 October	5 days later	+1.1 days per decade
Growing days	169 days	164 days	180 days	16 days more	+2.8 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

99 years, 1917 to 2018

A day with at least 57.9 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 123.2 mm (4.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Wilmington 3 N: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	57.9 mm (2.3 in)
5 years	75.1 mm (3.0 in)
10 years	86.6 mm (3.4 in)
25 years	101.2 mm (4.0 in)
50 years	112.2 mm (4.4 in)
100 years	123.2 mm (4.9 in)	Longer than the 99 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, 99 years of values from 1917 to 2018.

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: 135.9 mm (5.4 in) in 1954; 122.4 mm (4.8 in) in 1975; 111.3 mm (4.4 in) in 1968.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Wilmington 3 N, at 1952. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1952 ran 0.2 C (0.4 F) lower than in the years before (possible change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1952	-0.2	-0.4	possible	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

2000 to 2017 against 1961 to 1990

Over 2000 to 2017, Wilmington 3 N had a mean temperature of 11.1 C (52.0 F) and 1,109.1 mm (43.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Seymour 1 WSW (United States, 189 km away), Greensburg (United States, 144 km away) and Oolitic Purdue Ex Fm (United States, 245 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Seymour 1 WSW	United States	189 km (117 mi)	11.3 C (52.3 F)	1,075.7 mm (42.4 in)	0.38
Greensburg	United States	144 km (89 mi)	11.1 C (52.1 F)	1,067.5 mm (42.0 in)	0.41
Oolitic Purdue Ex Fm	United States	245 km (152 mi)	11.3 C (52.3 F)	1,133.2 mm (44.6 in)	0.44

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.
