A day with at least 30.1 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 87.0 mm (3.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Guadalajara (Instituto): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	30.1 mm (1.2 in)
5 years	41.3 mm (1.6 in)
10 years	50.0 mm (2.0 in)
25 years	63.0 mm (2.5 in)
50 years	74.3 mm (2.9 in)	Longer than the 30 years of record
100 years	87.0 mm (3.4 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 1951 to 1984.

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: 65.0 mm (2.6 in) in 1961; 65.0 mm (2.6 in) in 1972; 55.0 mm (2.2 in) in 1975.
