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
61 years with a frost
Across 61 years with a frost, the median last spring frost at Chiricahua Nm falls on 2 May and the median first autumn frost on 31 October, which leaves a median of 185 days between them.
In 1972 to 2005 the median growing season was 192 days. That is 13 days more than in 1909 to 1970.
Fitted over all years, the growing season changes by +3.0 days per decade at this station.

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
81 years, 1909 to 2024
A day with at least 43.0 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 96.1 mm (3.8 in) of rain is expected about once in 100 years.

Longer than the 81 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, 81 years of values from 1909 to 2024.
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: 114.3 mm (4.5 in) in 1911; 81.3 mm (3.2 in) in 1996; 80.8 mm (3.2 in) in 1913.
