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

74 years with a frost

Across 74 years with a frost, the median last spring frost at Madill falls on 25 March and the median first autumn frost on 9 November, which leaves a median of 230 days between them.

In 1988 to 2019 the median growing season was 231 days. That is 4 days more than in 1937 to 1973.

Fitted over all years, the growing season changes by +1.3 days per decade at this station.

Frost dates and growing season at Madill
Measure	Median, all years	Earliest period (1937 to 1973)	Recent period (1988 to 2019)	Recent against earliest	Fitted trend
Last spring frost	25 March	28 March	25 March	3 days earlier	-0.8 days per decade
First autumn frost	9 November	8 November	5 November	3 days earlier	+0.4 days per decade
Growing days	230 days	227 days	231 days	4 days more	+1.3 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, 1937 to 2025

A day with at least 87.7 mm (3.5 in) of rain is expected about once in 2 years. A day with at least 206.4 mm (8.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Madill: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	87.7 mm (3.5 in)
5 years	117.9 mm (4.6 in)
10 years	138.5 mm (5.5 in)
25 years	165.3 mm (6.5 in)
50 years	185.7 mm (7.3 in)
100 years	206.4 mm (8.1 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 1937 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: 258.3 mm (10.2 in) in 1981; 185.4 mm (7.3 in) in 2015; 166.9 mm (6.6 in) in 1957.

Station Changes

1 suspected

One change was suspected in the annual mean temperature of Madill, at 1965. Each is measured against neighbouring stations.

Relative to 5 neighbouring stations, the station's annual mean temperature from 1965 ran 0.2 C (0.4 F) higher than in the years before (likely change).

Year	Shift (C)	Shift (F)	Strength	Neighbours
1965	+0.2	+0.4	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

2005 to 2019 against 1961 to 1990

Over 2005 to 2019, Madill had a mean temperature of 17.3 C (63.1 F) and 1,018.7 mm (40.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Seminole (United States, 127 km away), Greenville Kgvl Radio (United States, 120 km away) and Paris (United States, 121 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Seminole	United States	127 km (79 mi)	16.8 C (62.3 F)	973.2 mm (38.3 in)	0.69
Greenville Kgvl Radio	United States	120 km (75 mi)	17.0 C (62.6 F)	1,071.1 mm (42.2 in)	0.70
Paris	United States	121 km (75 mi)	17.3 C (63.2 F)	1,163.3 mm (45.8 in)	0.79

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.
