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

57 years with a frost

Across 57 years with a frost, the median last spring frost at Aspermont falls on 27 March and the median first autumn frost on 10 November, which leaves a median of 227 days between them.

Fitted over all years, the growing season changes by -0.7 days per decade at this station.

Frost dates and growing season at Aspermont
Measure	Median, all years	Earliest period	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	27 March	n/a	27 March	n/a	0.0 days per decade
First autumn frost	10 November	n/a	9 November	n/a	-0.7 days per decade
Growing days	227 days	n/a	228 days	n/a	-0.7 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

109 years, 1912 to 2025

A day with at least 61.3 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 164.0 mm (6.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Aspermont: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	61.3 mm (2.4 in)
5 years	83.7 mm (3.3 in)
10 years	100.4 mm (4.0 in)
25 years	123.8 mm (4.9 in)
50 years	143.1 mm (5.6 in)
100 years	164.0 mm (6.5 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 109 years of values from 1912 to 2025.

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: 175.8 mm (6.9 in) in 1930; 153.7 mm (6.1 in) in 2000; 138.4 mm (5.4 in) in 1955.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Aspermont, at 1991 and 2007. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1991 ran 0.4 C (0.8 F) lower than in the years before (likely change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2007 ran 0.3 C (0.5 F) higher than in the years before (likely change).

Suspected changes in the annual mean temperature at Aspermont, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
1991	-0.4	-0.8	likely	5
2007	+0.3	+0.5	likely	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.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Aspermont had a mean temperature of 18.2 C (64.7 F) and 575.5 mm (22.7 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Robert Lee 4WSW (United States, 144 km away), Breckenridge (United States, 132 km away) and Olney (United States, 139 km away).

Climate twins of Aspermont: stations whose 1961 to 1990 climate is closest to its 2011 to 2025 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Robert Lee 4WSW	United States	144 km (89 mi)	18.0 C (64.3 F)	600.4 mm (23.6 in)	0.72
Breckenridge	United States	132 km (82 mi)	17.8 C (64.1 F)	670.5 mm (26.4 in)	0.78
Olney	United States	139 km (86 mi)	18.1 C (64.6 F)	708.4 mm (27.9 in)	0.91

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.
