Rainfall Return Levels

34 years, 1967 to 2009

A day with at least 35.4 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 64.2 mm (2.5 in) of rain is expected about once in 100 years.

Rainfall return levels at San Diego Texmelucan: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	35.4 mm (1.4 in)
5 years	44.3 mm (1.7 in)
10 years	49.7 mm (2.0 in)
25 years	56.0 mm (2.2 in)
50 years	60.3 mm (2.4 in)	Longer than the 34 years of record
100 years	64.2 mm (2.5 in)	Longer than the 34 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, 34 years of values from 1967 to 2009.

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: 56.4 mm (2.2 in) in 1976; 54.6 mm (2.1 in) in 1989; 53.6 mm (2.1 in) in 1992.
