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.

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
117 years, 1894 to 2013
A day with at least 34.6 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 78.2 mm (3.1 in) of rain is expected about once in 100 years.

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 117 years of values from 1894 to 2013.
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: 77.9 mm (3.1 in) in 1956; 77.3 mm (3.0 in) in 1898; 65.5 mm (2.6 in) in 1927.
Station Changes
3 suspected
3 changes were suspected in the annual mean temperature of Ulm, at 1965, 1983 and 1992. Each is measured against neighbouring stations.
Relative to 5 neighbouring stations, the station's annual mean temperature from 1965 ran 0.3 C (0.5 F) lower than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1983 ran 0.2 C (0.4 F) higher than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 1992 ran 0.3 C (0.5 F) lower than in the years before (likely change).

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.
