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

79 years with a frost

Across 79 years with a frost, the median last spring frost at Warsaw 1 falls on 20 April and the median first autumn frost on 17 October, which leaves a median of 181 days between them.

In 1952 to 1983 the median growing season was 180 days. That is 3 days more than in 1895 to 1932.

Fitted over all years, the growing season changes by +0.5 days per decade at this station.

Frost dates and growing season at Warsaw 1
Measure	Median, all years	Earliest period (1895 to 1932)	Recent period (1952 to 1983)	Recent against earliest	Fitted trend
Last spring frost	20 April	25 April	23 April	2 days earlier	0.0 days per decade
First autumn frost	17 October	12 October	17 October	5 days later	+0.6 days per decade
Growing days	181 days	177 days	180 days	3 days more	+0.5 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

80 years, 1897 to 1983

A day with at least 73.1 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 181.1 mm (7.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Warsaw 1: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	73.1 mm (2.9 in)
5 years	96.8 mm (3.8 in)
10 years	114.3 mm (4.5 in)
25 years	139.0 mm (5.5 in)
50 years	159.2 mm (6.3 in)
100 years	181.1 mm (7.1 in)	Longer than the 80 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, 80 years of values from 1897 to 1983.

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: 215.9 mm (8.5 in) in 1906; 142.2 mm (5.6 in) in 1946; 141.2 mm (5.6 in) in 1919.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Warsaw 1, at 1957. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1957 ran 0.2 C (0.4 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Warsaw 1, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1957	-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.
