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

75 years with a frost

Across 75 years with a frost, the median last spring frost at Park River falls on 15 May and the median first autumn frost on 22 September, which leaves a median of 129 days between them.

In 1960 to 1994 the median growing season was 135 days. That is 14 days more than in 1905 to 1944.

Fitted over all years, the growing season changes by +2.9 days per decade at this station.

Frost dates and growing season at Park River
Measure	Median, all years	Earliest period (1905 to 1944)	Recent period (1960 to 1994)	Recent against earliest	Fitted trend
Last spring frost	15 May	23 May	13 May	10 days earlier	-1.6 days per decade
First autumn frost	22 September	19 September	24 September	5 days later	+1.3 days per decade
Growing days	129 days	121 days	135 days	14 days more	+2.9 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

71 years, 1904 to 1994

A day with at least 44.0 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 122.6 mm (4.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Park River: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	44.0 mm (1.7 in)
5 years	59.7 mm (2.4 in)
10 years	71.9 mm (2.8 in)
25 years	89.9 mm (3.5 in)
50 years	105.3 mm (4.1 in)
100 years	122.6 mm (4.8 in)	Longer than the 71 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, 71 years of values from 1904 to 1994.

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: 132.1 mm (5.2 in) in 1957; 102.9 mm (4.1 in) in 1956; 91.2 mm (3.6 in) in 1949.
