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 at Plains
Measure	Median, all years	Earliest period	Recent period (1983 to 2025)	Recent against earliest	Fitted trend
Last spring frost	14 April	n/a	13 April	n/a	-0.2 days per decade
First autumn frost	29 October	n/a	3 November	n/a	+1.1 days per decade
Growing days	198 days	n/a	200 days	n/a	+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.

70 years, 1925 to 2025

A day with at least 51.1 mm (2.0 in) of rain is expected about once in 2 years. A day with at least 183.1 mm (7.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Plains: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	51.1 mm (2.0 in)
5 years	76.0 mm (3.0 in)
10 years	96.0 mm (3.8 in)
25 years	126.2 mm (5.0 in)
50 years	152.7 mm (6.0 in)
100 years	183.1 mm (7.2 in)	Longer than the 70 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, 70 years of values from 1925 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: 155.2 mm (6.1 in) in 1960; 152.4 mm (6.0 in) in 1955; 141.0 mm (5.6 in) in 1958.

Climate Twins

2011 to 2025 against 1961 to 1990

Over 2011 to 2025, Plains had a mean temperature of 15.9 C (60.6 F) and 354.9 mm (14.0 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Roswell Ind Air Pk (United States, 157 km away), Lubbock (United States, 107 km away) and Lordsburg 4 SE (United States, 553 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Roswell Ind Air Pk	United States	157 km (98 mi)	15.9 C (60.6 F)	310.9 mm (12.2 in)	0.56
Lubbock	United States	107 km (66 mi)	15.6 C (60.0 F)	474.5 mm (18.7 in)	0.77
Lordsburg 4 SE	United States	553 km (344 mi)	15.7 C (60.3 F)	301.5 mm (11.9 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.
