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

94 years with a frost

Across 94 years with a frost, the median last spring frost at Aztec Ruins Nm falls on 15 May and the median first autumn frost on 7 October, which leaves a median of 144 days between them.

In 1986 to 2022 the median growing season was 147 days. That is 2 days more than in 1895 to 1950.

Fitted over all years, the growing season changes by -0.1 days per decade at this station.

Frost dates and growing season at Aztec Ruins Nm
Measure	Median, all years	Earliest period (1895 to 1950)	Recent period (1986 to 2022)	Recent against earliest	Fitted trend
Last spring frost	15 May	17 May	13 May	4 days earlier	-0.1 days per decade
First autumn frost	7 October	10 October	8 October	2 days earlier	-0.2 days per decade
Growing days	144 days	145 days	147 days	2 days more	-0.1 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

112 years, 1895 to 2023

A day with at least 22.7 mm (0.9 in) of rain is expected about once in 2 years. A day with at least 52.0 mm (2.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Aztec Ruins Nm: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	22.7 mm (0.9 in)
5 years	30.3 mm (1.2 in)
10 years	35.4 mm (1.4 in)
25 years	42.0 mm (1.7 in)
50 years	47.0 mm (1.9 in)
100 years	52.0 mm (2.0 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 112 years of values from 1895 to 2023.

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: 67.8 mm (2.7 in) in 2015; 47.0 mm (1.9 in) in 1911; 46.2 mm (1.8 in) in 1929.

No change in the annual mean temperature of this station was found against its neighbours.

Climate Twins

2001 to 2022 against 1961 to 1990

Over 2001 to 2022, Aztec Ruins Nm had a mean temperature of 11.8 C (53.3 F) and 257.0 mm (10.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Gateway 1ENE (United States, 223 km away), Holbrook (United States, 289 km away) and Pueblo Mem AP (United States, 348 km away).

Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Gateway 1ENE	United States	223 km (139 mi)	11.8 C (53.2 F)	299.4 mm (11.8 in)	0.49

Pueblo Mem AP	United States	348 km (216 mi)	11.5 C (52.7 F)	285.1 mm (11.2 in)	0.61

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.
