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

20 years with a frost

Across 20 years with a frost, the median last spring frost at Passau-Maierhof falls on 2 May and the median first autumn frost on 11 October, which leaves a median of 161 days between them.

Frost dates and growing season at Passau-Maierhof
Measure	Median, all years	Earliest period	Recent period (1936 to 1957)	Recent against earliest	Fitted trend
Last spring frost	2 May	n/a	2 May	n/a	n/a
First autumn frost	11 October	n/a	11 October	n/a	n/a
Growing days	161 days	n/a	161 days	n/a	n/a

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

128 years, 1879 to 2025

A day with at least 36.6 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 81.5 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Passau-Maierhof: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	36.6 mm (1.4 in)
5 years	47.2 mm (1.9 in)
10 years	54.8 mm (2.2 in)
25 years	65.0 mm (2.6 in)
50 years	73.1 mm (2.9 in)
100 years	81.5 mm (3.2 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 128 years of values from 1879 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: 93.0 mm (3.7 in) in 1964; 80.6 mm (3.2 in) in 2002; 78.0 mm (3.1 in) in 1960.
