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

91 years with a frost

Across 91 years with a frost, the median last spring frost at Wahpeton 3 N falls on 13 May and the median first autumn frost on 23 September, which leaves a median of 134 days between them.

In 1966 to 1998 the median growing season was 145 days. That is 26 days more than in 1893 to 1933.

Fitted over all years, the growing season changes by +3.4 days per decade at this station.

Frost dates and growing season at Wahpeton 3 N
Measure	Median, all years	Earliest period (1893 to 1933)	Recent period (1966 to 1998)	Recent against earliest	Fitted trend
Last spring frost	13 May	19 May	8 May	11 days earlier	-1.9 days per decade
First autumn frost	23 September	19 September	28 September	9 days later	+1.5 days per decade
Growing days	134 days	119 days	145 days	26 days more	+3.4 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

98 years, 1893 to 1998

A day with at least 48.3 mm (1.9 in) of rain is expected about once in 2 years. A day with at least 142.8 mm (5.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Wahpeton 3 N: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	48.3 mm (1.9 in)
5 years	68.0 mm (2.7 in)
10 years	83.0 mm (3.3 in)
25 years	104.6 mm (4.1 in)
50 years	122.8 mm (4.8 in)
100 years	142.8 mm (5.6 in)	Longer than the 98 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, 98 years of values from 1893 to 1998.

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: 123.4 mm (4.9 in) in 1962; 115.6 mm (4.6 in) in 1904; 115.1 mm (4.5 in) in 1898.
