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

63 years with a frost

Across 63 years with a frost, the median last spring frost at Jever falls on 26 April and the median first autumn frost on 29 October, which leaves a median of 187 days between them.

In 1974 to 2003 the median growing season was 190 days. That is 3 days more than in 1940 to 1970.

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

Frost dates and growing season at Jever
Measure	Median, all years	Earliest period (1940 to 1970)	Recent period (1974 to 2003)	Recent against earliest	Fitted trend
Last spring frost	26 April	29 April	20 April	9 days earlier	-1.6 days per decade
First autumn frost	29 October	29 October	5 November	7 days later	+1.0 days per decade
Growing days	187 days	187 days	190 days	3 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

64 years, 1940 to 2004

A day with at least 30.6 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 81.8 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Jever: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	30.6 mm (1.2 in)
5 years	40.2 mm (1.6 in)
10 years	47.9 mm (1.9 in)
25 years	59.6 mm (2.3 in)
50 years	70.0 mm (2.8 in)
100 years	81.8 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 1940 to 2004.

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: 84.8 mm (3.3 in) in 1981; 68.9 mm (2.7 in) in 1973; 66.5 mm (2.6 in) in 1958.
