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

81 years with a frost

Across 81 years with a frost, the median last spring frost at Allardt falls on 21 April and the median first autumn frost on 15 October, which leaves a median of 178 days between them.

In 1986 to 2020 the median growing season was 182 days. That is 18 days more than in 1928 to 1964.

Fitted over all years, the growing season changes by +3.2 days per decade at this station.

Frost dates and growing season at Allardt
Measure	Median, all years	Earliest period (1928 to 1964)	Recent period (1986 to 2020)	Recent against earliest	Fitted trend
Last spring frost	21 April	30 April	19 April	11 days earlier	-1.8 days per decade
First autumn frost	15 October	11 October	19 October	8 days later	+1.4 days per decade
Growing days	178 days	164 days	182 days	18 days more	+3.2 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

92 years, 1928 to 2021

A day with at least 72.4 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 151.0 mm (5.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Allardt: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	72.4 mm (2.9 in)
5 years	93.7 mm (3.7 in)
10 years	107.7 mm (4.2 in)
25 years	125.3 mm (4.9 in)
50 years	138.3 mm (5.4 in)
100 years	151.0 mm (5.9 in)	Longer than the 92 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, 92 years of values from 1928 to 2021.

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: 171.5 mm (6.8 in) in 1928; 137.7 mm (5.4 in) in 2011; 125.7 mm (4.9 in) in 1944.

Climate Twins

2006 to 2020 against 1961 to 1990

Over 2006 to 2020, Allardt had a mean temperature of 13.1 C (55.6 F) and 1,596.8 mm (62.9 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Brevard (United States, 232 km away), Monteagle (United States, 155 km away) and Andrews (United States, 161 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference

Andrews	United States	161 km (100 mi)	12.6 C (54.6 F)	1,558.3 mm (61.4 in)	0.65

Twins are stations, not cities. A twin is one of the three stations at least 100 km away whose earlier climate is closest to this station's recent one, so a close match does not mean the two places look alike in other ways. A station move or a gap in a record can change that station's averages. The list describes past climate; it is not a forecast and does not say what caused any change. How twins are found, and a search for any station.
