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.

25 years	71.3 mm (2.8 in)
50 years	79.9 mm (3.1 in)
100 years	88.3 mm (3.5 in)	Longer than the 79 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, 79 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: 91.4 mm (3.6 in) in 2018; 88.4 mm (3.5 in) in 1951; 74.2 mm (2.9 in) in 2013.

Climate Twins

2002 to 2023 against 1961 to 1990

Over 2002 to 2023, Organ Pipe Cactus Nm had a mean temperature of 22.2 C (71.9 F) and 230.9 mm (9.1 in) of rain a year. The 3 stations whose 1961 to 1990 climate was closest to that are Borrego Desert Park (United States, 367 km away), Kofa Mine (United States, 183 km away) and Presa Morelos (Mexico, 198 km away).

Climate twins of Organ Pipe Cactus Nm: stations whose 1961 to 1990 climate is closest to its 2002 to 2023 climate
Twin station	Country	Distance away	Mean temperature, 1961-1990	Rain a year, 1961-1990	Climate difference
Borrego Desert Park	United States	367 km (228 mi)	22.6 C (72.6 F)	174.7 mm (6.9 in)	0.63
Kofa Mine	United States	183 km (114 mi)	22.6 C (72.6 F)	161.3 mm (6.4 in)	0.76
Presa Morelos	Mexico	198 km (123 mi)	22.0 C (71.5 F)	72.6 mm (2.9 in)	0.77

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.
