30 years, 1981 to 2012

A day with at least 42.8 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 125.9 mm (5.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Igualita: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	42.8 mm (1.7 in)
5 years	61.6 mm (2.4 in)
10 years	75.3 mm (3.0 in)
25 years	94.2 mm (3.7 in)
50 years	109.5 mm (4.3 in)	Longer than the 30 years of record
100 years	125.9 mm (5.0 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: 125.0 mm (4.9 in) in 1989; 84.8 mm (3.3 in) in 1998; 84.8 mm (3.3 in) in 2009.
