30 years, 1981 to 2012

A day with at least 62.1 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 113.4 mm (4.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Apancingo: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	62.1 mm (2.4 in)
5 years	81.7 mm (3.2 in)
10 years	91.9 mm (3.6 in)
25 years	102.2 mm (4.0 in)
50 years	108.3 mm (4.3 in)	Longer than the 30 years of record
100 years	113.4 mm (4.5 in)	Longer than the 30 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, 30 years of values from 1981 to 2012.

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: 112.8 mm (4.4 in) in 2012; 95.8 mm (3.8 in) in 1999; 95.0 mm (3.7 in) in 1987.
