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.

50 years	73.6 mm (2.9 in)
100 years	84.2 mm (3.3 in)	Longer than the 88 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, 88 years of values from 1931 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: 103.3 mm (4.1 in) in 2006; 88.7 mm (3.5 in) in 1994; 65.4 mm (2.6 in) in 1984.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Dillenburg, at 1995. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1995 ran 0.2 C (0.3 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Dillenburg, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1995	+0.2	+0.3	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

2007 to 2021 against 1961 to 1990

Over 2007 to 2021, Dillenburg had a mean temperature of 9.4 C (48.8 F) and 773.8 mm (30.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Pforzheim-Eutingen (Germany, 206 km away), Trier-Petrisberg (Germany, 158 km away) and Neunkirchen-Wellesweiler (Germany, 171 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Pforzheim-Eutingen	Germany	206 km (128 mi)	9.3 C (48.8 F)	780.5 mm (30.7 in)	0.48
Trier-Petrisberg	Germany	158 km (98 mi)	9.4 C (48.9 F)	784.2 mm (30.9 in)	0.52
Neunkirchen-Wellesweiler	Germany	171 km (106 mi)	9.3 C (48.7 F)	836.0 mm (32.9 in)	0.52

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.
