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 Coalville falls on 15 June and the median first autumn frost on 31 August, which leaves a median of 78 days between them.

In 1981 to 2010 the median growing season was 82 days. That is 14 days more than in 1931 to 1973.

Fitted over all years, the growing season changes by +4.5 days per decade at this station.

Frost dates and growing season at Coalville
Measure	Median, all years	Earliest period (1931 to 1973)	Recent period (1981 to 2010)	Recent against earliest	Fitted trend
Last spring frost	15 June	18 June	12 June	6 days earlier	-1.4 days per decade
First autumn frost	31 August	26 August	4 September	9 days later	+3.1 days per decade
Growing days	78 days	68 days	82 days	14 days more	+4.5 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

67 years, 1940 to 2010

A day with at least 25.6 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 54.4 mm (2.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Coalville: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	25.6 mm (1.0 in)
5 years	32.0 mm (1.3 in)
10 years	36.7 mm (1.4 in)
25 years	43.2 mm (1.7 in)
50 years	48.6 mm (1.9 in)
100 years	54.4 mm (2.1 in)	Longer than the 67 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, 67 years of values from 1940 to 2010.

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: 66.0 mm (2.6 in) in 1986; 44.7 mm (1.8 in) in 1945; 43.7 mm (1.7 in) in 1985.
