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

99 years with a frost

Across 99 years with a frost, the median last spring frost at Dubois Exp STN falls on 29 May and the median first autumn frost on 20 September, which leaves a median of 115 days between them.

In 1995 to 2025 the median growing season was 118 days. That is 7 days more than in 1925 to 1955.

Fitted over all years, the growing season changes by +2.2 days per decade at this station.

Frost dates and growing season at Dubois Exp STN
Measure	Median, all years	Earliest period (1925 to 1955)	Recent period (1995 to 2025)	Recent against earliest	Fitted trend
Last spring frost	29 May	30 May	30 May	no change	-0.4 days per decade
First autumn frost	20 September	16 September	27 September	11 days later	+1.7 days per decade
Growing days	115 days	111 days	118 days	7 days more	+2.2 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

96 years, 1925 to 2022

A day with at least 23.2 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 52.2 mm (2.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Dubois Exp STN: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	23.2 mm (0.9 in)
5 years	30.3 mm (1.2 in)
10 years	35.2 mm (1.4 in)
25 years	41.8 mm (1.6 in)
50 years	47.0 mm (1.9 in)
100 years	52.2 mm (2.1 in)	Longer than the 96 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, 96 years of values from 1925 to 2022.

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: 66.0 mm (2.6 in) in 1944; 50.8 mm (2.0 in) in 1925; 42.9 mm (1.7 in) in 1932.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Dubois Exp STN, at 1986. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1986 ran 0.3 C (0.6 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1986	+0.3	+0.6	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, Dubois Exp STN had a mean temperature of 7.8 C (46.0 F) and 292.1 mm (11.5 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Thiokol Propulsion F S (United States, 281 km away), Dinosaur Nm (United States, 518 km away) and Biddle 8 SW (United States, 539 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Thiokol Propulsion F S	United States	281 km (175 mi)	8.2 C (46.8 F)	364.0 mm (14.3 in)	0.76
Dinosaur Nm	United States	518 km (322 mi)	8.3 C (46.9 F)	289.0 mm (11.4 in)	0.77
Biddle 8 SW	United States	539 km (335 mi)	7.4 C (45.2 F)	342.3 mm (13.5 in)	0.80

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.
