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

66 years with a frost

Across 66 years with a frost, the median last spring frost at Hameln falls on 23 April and the median first autumn frost on 30 October, which leaves a median of 190 days between them.

In 1977 to 2006 the median growing season was 194 days. That is 6 days more than in 1940 to 1970.

Fitted over all years, the growing season changes by +3.1 days per decade at this station.

Frost dates and growing season at Hameln
Measure	Median, all years	Earliest period (1940 to 1970)	Recent period (1977 to 2006)	Recent against earliest	Fitted trend
Last spring frost	23 April	25 April	20 April	5 days earlier	-1.2 days per decade
First autumn frost	30 October	24 October	4 November	11 days later	+1.9 days per decade
Growing days	190 days	188 days	194 days	6 days more	+3.1 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

67 years, 1940 to 2006

A day with at least 32.0 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 71.9 mm (2.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Hameln: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	32.0 mm (1.3 in)
5 years	41.7 mm (1.6 in)
10 years	48.6 mm (1.9 in)
25 years	57.6 mm (2.3 in)
50 years	64.6 mm (2.5 in)
100 years	71.9 mm (2.8 in)	Longer than the 67 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, 67 years of values from 1940 to 2006.

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: 81.1 mm (3.2 in) in 2002; 61.2 mm (2.4 in) in 1981; 56.6 mm (2.2 in) in 1947.
