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

60 years with a frost

Across 60 years with a frost, the median last spring frost at Coldwater falls on 11 April and the median first autumn frost on 21 October, which leaves a median of 193 days between them.

In 1940 to 1975 the median growing season was 193 days. That is 4 days fewer than in 1898 to 1938.

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

Frost dates and growing season at Coldwater
Measure	Median, all years	Earliest period (1898 to 1938)	Recent period (1940 to 1975)	Recent against earliest	Fitted trend
Last spring frost	11 April	10 April	14 April	4 days later	+1.4 days per decade
First autumn frost	21 October	25 October	18 October	7 days earlier	-1.5 days per decade
Growing days	193 days	197 days	193 days	4 days fewer	-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

70 years, 1898 to 1975

A day with at least 77.8 mm (3.1 in) of rain is expected about once in 2 years. A day with at least 175.1 mm (6.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Coldwater: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	77.8 mm (3.1 in)
5 years	101.4 mm (4.0 in)
10 years	117.9 mm (4.6 in)
25 years	140.0 mm (5.5 in)
50 years	157.2 mm (6.2 in)
100 years	175.1 mm (6.9 in)	Longer than the 70 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, 70 years of values from 1898 to 1975.

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: 170.2 mm (6.7 in) in 1973; 148.1 mm (5.8 in) in 1929; 147.3 mm (5.8 in) in 1969.
