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

72 years with a frost

Across 72 years with a frost, the median last spring frost at Dull Ctr 1SE falls on 19 May and the median first autumn frost on 21 September, which leaves a median of 126 days between them.

In 1987 to 2020 the median growing season was 133 days. That is 11 days more than in 1933 to 1972.

Fitted over all years, the growing season changes by +1.1 days per decade at this station.

Frost dates and growing season at Dull Ctr 1SE
Measure	Median, all years	Earliest period (1933 to 1972)	Recent period (1987 to 2020)	Recent against earliest	Fitted trend
Last spring frost	19 May	20 May	14 May	6 days earlier	-0.5 days per decade
First autumn frost	21 September	21 September	23 September	2 days later	+0.5 days per decade
Growing days	126 days	122 days	133 days	11 days more	+1.1 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

84 years, 1933 to 2021

A day with at least 33.2 mm (1.3 in) of rain is expected about once in 2 years. A day with at least 84.9 mm (3.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Dull Ctr 1SE: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	33.2 mm (1.3 in)
5 years	46.0 mm (1.8 in)
10 years	54.9 mm (2.2 in)
25 years	66.6 mm (2.6 in)
50 years	75.6 mm (3.0 in)
100 years	84.9 mm (3.3 in)	Longer than the 84 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, 84 years of values from 1933 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: 82.3 mm (3.2 in) in 1999; 81.3 mm (3.2 in) in 1952; 65.5 mm (2.6 in) in 1933.

Climate Twins

2002 to 2020 against 1961 to 1990

Over 2002 to 2020, Dull Ctr 1SE had a mean temperature of 8.8 C (47.8 F) and 343.8 mm (13.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Oral (United States, 137 km away), Hemingford (United States, 196 km away) and Midwest (United States, 106 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Oral	United States	137 km (85 mi)	8.8 C (47.8 F)	390.2 mm (15.4 in)	0.82
Hemingford	United States	196 km (122 mi)	8.5 C (47.3 F)	438.8 mm (17.3 in)	0.84
Midwest	United States	106 km (66 mi)	8.4 C (47.1 F)	335.1 mm (13.2 in)	0.84

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.
