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.

Across 61 years with a frost, the median last spring frost at Wishek falls on 22 May and the median first autumn frost on 13 September, which leaves a median of 115 days between them.

In 1971 to 2012 the median growing season was 127 days. That is 21 days more than in 1931 to 1969.

Fitted over all years, the growing season changes by +3.3 days per decade at this station.

Frost dates and growing season at Wishek
Measure	Median, all years	Earliest period (1931 to 1969)	Recent period (1971 to 2012)	Recent against earliest	Fitted trend
Last spring frost	22 May	24 May	17 May	7 days earlier	-1.2 days per decade
First autumn frost	13 September	10 September	21 September	11 days later	+2.1 days per decade
Growing days	115 days	106 days	127 days	21 days more	+3.3 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

63 years, 1905 to 2012

A day with at least 45.0 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 118.6 mm (4.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Wishek: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	45.0 mm (1.8 in)
5 years	63.5 mm (2.5 in)
10 years	76.3 mm (3.0 in)
25 years	92.9 mm (3.7 in)
50 years	105.6 mm (4.2 in)
100 years	118.6 mm (4.7 in)	Longer than the 63 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, 63 years of values from 1905 to 2012.

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: 106.9 mm (4.2 in) in 1953; 100.1 mm (3.9 in) in 1932; 94.0 mm (3.7 in) in 1991.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Wishek, at 1978. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1978 ran 0.4 C (0.7 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours

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.
