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

21 years with a frost

Across 21 years with a frost, the median last spring frost at Downing falls on 23 April and the median first autumn frost on 22 October, which leaves a median of 178 days between them.

Frost dates and growing season at Downing
Measure	Median, all years	Earliest period	Recent period (1923 to 2017)	Recent against earliest	Fitted trend
Last spring frost	23 April	n/a	23 April	n/a	n/a
First autumn frost	22 October	n/a	22 October	n/a	n/a
Growing days	178 days	n/a	178 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

52 years, 1894 to 2017

A day with at least 68.4 mm (2.7 in) of rain is expected about once in 2 years. A day with at least 164.6 mm (6.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Downing: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	68.4 mm (2.7 in)
5 years	90.8 mm (3.6 in)
10 years	106.9 mm (4.2 in)
25 years	128.7 mm (5.1 in)
50 years	146.2 mm (5.8 in)
100 years	164.6 mm (6.5 in)	Longer than the 52 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, 52 years of values from 1894 to 2017.

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: 147.8 mm (5.8 in) in 2015; 141.2 mm (5.6 in) in 2008; 135.1 mm (5.3 in) in 2007.
