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

85 years with a frost

Across 85 years with a frost, the median last spring frost at Hallock falls on 24 May and the median first autumn frost on 18 September, which leaves a median of 114 days between them.

In 1959 to 2024 the median growing season was 134 days. That is 28 days more than in 1900 to 1931.

Fitted over all years, the growing season changes by +4.0 days per decade at this station.

Frost dates and growing season at Hallock
Measure	Median, all years	Earliest period (1900 to 1931)	Recent period (1959 to 2024)	Recent against earliest	Fitted trend
Last spring frost	24 May	3 June	18 May	16 days earlier	-2.3 days per decade
First autumn frost	18 September	15 September	25 September	10 days later	+1.7 days per decade
Growing days	114 days	106 days	134 days	28 days more	+4.0 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

97 years, 1901 to 2025

A day with at least 44.9 mm (1.8 in) of rain is expected about once in 2 years. A day with at least 137.2 mm (5.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Hallock: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	44.9 mm (1.8 in)
5 years	64.1 mm (2.5 in)
10 years	78.7 mm (3.1 in)
25 years	99.8 mm (3.9 in)
50 years	117.6 mm (4.6 in)
100 years	137.2 mm (5.4 in)	Longer than the 97 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, 97 years of values from 1901 to 2025.

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: 136.1 mm (5.4 in) in 1956; 111.5 mm (4.4 in) in 1957; 111.0 mm (4.4 in) in 2020.
