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

80 years with a frost

Across 80 years with a frost, the median last spring frost at Wagner falls on 3 May and the median first autumn frost on 1 October, which leaves a median of 154 days between them.

In 1981 to 2010 the median growing season was 160 days. That is 13 days more than in 1918 to 1959.

Fitted over all years, the growing season changes by +2.3 days per decade at this station.

Frost dates and growing season at Wagner
Measure	Median, all years	Earliest period (1918 to 1959)	Recent period (1981 to 2010)	Recent against earliest	Fitted trend
Last spring frost	3 May	7 May	27 April	10 days earlier	-1.2 days per decade
First autumn frost	1 October	28 September	2 October	4 days later	+1.2 days per decade
Growing days	154 days	147 days	160 days	13 days more	+2.3 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

89 years, 1916 to 2010

A day with at least 51.8 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 115.2 mm (4.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Wagner: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	51.8 mm (2.0 in)
5 years	68.4 mm (2.7 in)
10 years	79.6 mm (3.1 in)
25 years	93.8 mm (3.7 in)
50 years	104.5 mm (4.1 in)
100 years	115.2 mm (4.5 in)	Longer than the 89 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, 89 years of values from 1916 to 2010.

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: 141.2 mm (5.6 in) in 1936; 87.6 mm (3.4 in) in 1934; 87.1 mm (3.4 in) in 1985.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Wagner, at 1987. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1987 ran 0.3 C (0.5 F) lower than in the years before (likely change).

Suspected changes in the annual mean temperature at Wagner, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1987	-0.3	-0.5	likely	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.
