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

65 years with a frost

Across 65 years with a frost, the median last spring frost at Dialville 2 W falls on 17 March and the median first autumn frost on 13 November, which leaves a median of 242 days between them.

In 1941 to 1977 the median growing season was 244 days. That is 1 day more than in 1898 to 1935.

Fitted over all years, the growing season changes by +1.7 days per decade at this station.

Frost dates and growing season at Dialville 2 W
Measure	Median, all years	Earliest period (1898 to 1935)	Recent period (1941 to 1977)	Recent against earliest	Fitted trend
Last spring frost	17 March	19 March	16 March	3 days earlier	-0.3 days per decade
First autumn frost	13 November	13 November	19 November	6 days later	+1.4 days per decade
Growing days	242 days	243 days	244 days	1 day more	+1.7 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

108 years, 1898 to 2016

A day with at least 84.9 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 243.9 mm (9.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Dialville 2 W: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	84.9 mm (3.3 in)
5 years	116.2 mm (4.6 in)
10 years	140.9 mm (5.5 in)
25 years	177.2 mm (7.0 in)
50 years	208.6 mm (8.2 in)
100 years	243.9 mm (9.6 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 108 years of values from 1898 to 2016.

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: 243.8 mm (9.6 in) in 1940; 208.3 mm (8.2 in) in 1957; 205.7 mm (8.1 in) in 1989.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Dialville 2 W, at 1963. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1963 ran 0.2 C (0.3 F) higher than in the years before (possible change).

Suspected changes in the annual mean temperature at Dialville 2 W, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1963	+0.2	+0.3	possible	5

Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
