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 frostAcross 64 years with a frost, the median last spring frost at Alfhausen falls on 27 April and the median first autumn frost on 23 October, which leaves a median of 185 days between them.
In 1996 to 2025 the median growing season was 198 days. That is 38 days more than in 1961 to 1991.
Fitted over all years, the growing season changes by +9.0 days per decade at this station.
| Measure | Median, all years | Earliest period (1961 to 1991) | Recent period (1996 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 27 April | 1 May | 22 April | 9 days earlier | -2.9 days per decade |
| First autumn frost | 23 October | 14 October | 8 November | 25 days later | +6.2 days per decade |
| Growing days | 185 days | 160 days | 198 days | 38 days more | +9.0 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
64 years, 1961 to 2025A day with at least 29.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 80.5 mm (3.2 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 29.2 mm (1.1 in) | |
| 5 years | 37.4 mm (1.5 in) | |
| 10 years | 44.5 mm (1.8 in) | |
| 25 years | 56.1 mm (2.2 in) | |
| 50 years | 67.1 mm (2.6 in) | |
| 100 years | 80.5 mm (3.2 in) | Longer than the 64 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, 64 years of values from 1961 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: 88.5 mm (3.5 in) in 1981; 64.3 mm (2.5 in) in 2015; 55.7 mm (2.2 in) in 1998.
Station Changes
3 suspected3 changes were suspected in the annual mean temperature of Alfhausen, at 1979, 2005 and 2010. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1979 ran 0.3 C (0.5 F) higher than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2005 ran 0.4 C (0.7 F) lower than in the years before (likely change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 2010 ran 0.2 C (0.4 F) higher than in the years before (possible change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1979 | +0.3 | +0.5 | possible | 5 |
| 2005 | -0.4 | -0.7 | likely | 5 |
| 2010 | +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
2011 to 2025 against 1961 to 1990Over 2011 to 2025, Alfhausen had a mean temperature of 10.3 C (50.6 F) and 774.4 mm (30.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Dusseldorf (Germany, 154 km away), Dusseldorf-Sudfriedhof (Germany, 163 km away) and Uccle (Belgium, 309 km away).
| Twin station | Country | Distance away | Mean temperature, 1961-1990 | Rain a year, 1961-1990 | Climate difference |
|---|---|---|---|---|---|
| Dusseldorf | Germany | 154 km (96 mi) | 10.4 C (50.7 F) | 760.4 mm (29.9 in) | 0.37 |
| Dusseldorf-Sudfriedhof | Germany | 163 km (101 mi) | 10.3 C (50.6 F) | 756.8 mm (29.8 in) | 0.44 |
| Uccle | Belgium | 309 km (192 mi) | 10.1 C (50.2 F) | 821.2 mm (32.3 in) | 0.48 |
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.
