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

22 years with a frost

Across 22 years with a frost, the median last spring frost at Coalgate 1 WNW falls on 2 April and the median first autumn frost on 1 November, which leaves a median of 212 days between them.

Frost dates and growing season at Coalgate 1 WNW
Measure	Median, all years	Earliest period	Recent period (1937 to 1962)	Recent against earliest	Fitted trend
Last spring frost	2 April	n/a	2 April	n/a	n/a
First autumn frost	1 November	n/a	1 November	n/a	n/a
Growing days	212 days	n/a	212 days	n/a	n/a

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

42 years, 1937 to 1981

A day with at least 93.8 mm (3.7 in) of rain is expected about once in 2 years. A day with at least 281.6 mm (11.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Coalgate 1 WNW: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	93.8 mm (3.7 in)
5 years	133.3 mm (5.2 in)
10 years	163.3 mm (6.4 in)
25 years	206.2 mm (8.1 in)
50 years	242.1 mm (9.5 in)	Longer than the 42 years of record
100 years	281.6 mm (11.1 in)	Longer than the 42 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, 42 years of values from 1937 to 1981.

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: 248.9 mm (9.8 in) in 1981; 242.3 mm (9.5 in) in 1953; 205.7 mm (8.1 in) in 1970.
