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.

Measure	Median, all years	Earliest period (1944 to 1973)	Recent period (1996 to 2025)	Recent against earliest	Fitted trend
Last spring frost	10 April	8 April	16 April	8 days later	+1.0 days per decade
First autumn frost	25 October	25 October	29 October	4 days later	+0.7 days per decade
Growing days	194 days	199 days	192 days	7 days fewer	-0.2 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

82 years, 1944 to 2025

A day with at least 72.7 mm (2.9 in) of rain is expected about once in 2 years. A day with at least 182.1 mm (7.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Springfield 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	72.7 mm (2.9 in)
5 years	95.7 mm (3.8 in)
10 years	113.1 mm (4.5 in)
25 years	138.1 mm (5.4 in)
50 years	159.0 mm (6.3 in)
100 years	182.1 mm (7.2 in)	Longer than the 82 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, 82 years of values from 1944 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: 188.0 mm (7.4 in) in 2017; 175.3 mm (6.9 in) in 2024; 158.5 mm (6.2 in) in 1979.

Station Changes

2 suspected

2 changes were suspected in the annual mean temperature of Springfield Exp STN, at 2003 and 2018. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 2003 ran 0.3 C (0.5 F) higher than in the years before (possible change).
Relative to 5 neighbouring stations, the station's annual mean temperature from 2018 ran 0.3 C (0.5 F) lower than in the years before (possible change).

Suspected changes in the annual mean temperature at Springfield Exp STN, against neighbouring stations
Year	Shift (C)	Shift (F)	Strength	Neighbours
2003	+0.3	+0.5	possible	5
2018	-0.3	-0.5	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.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Springfield Exp STN had a mean temperature of 14.9 C (58.8 F) and 1,448.7 mm (57.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Ripley (United States, 271 km away), Holly Springs 4 N (United States, 298 km away) and Selmer (United States, 215 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Ripley	United States	271 km (168 mi)	15.2 C (59.3 F)	1,476.3 mm (58.1 in)	0.58
Holly Springs 4 N	United States	298 km (185 mi)	14.9 C (58.8 F)	1,428.2 mm (56.2 in)	0.58
Selmer	United States	215 km (134 mi)	14.6 C (58.3 F)	1,407.7 mm (55.4 in)	0.63

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.
