30 years, 1982 to 2012

A day with at least 54.2 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 80.3 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Dos Bocas: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	54.2 mm (2.1 in)
5 years	64.6 mm (2.5 in)
10 years	69.9 mm (2.8 in)
25 years	75.0 mm (3.0 in)
50 years	77.9 mm (3.1 in)	Longer than the 30 years of record
100 years	80.3 mm (3.2 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 1982 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: 83.3 mm (3.3 in) in 2012; 80.8 mm (3.2 in) in 2001; 68.6 mm (2.7 in) in 1982.
