A day with at least 105.7 mm (4.2 in) of rain is expected about once in 2 years. A day with at least 365.6 mm (14.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Garzas: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	105.7 mm (4.2 in)
5 years	151.1 mm (5.9 in)
10 years	188.9 mm (7.4 in)
25 years	248.1 mm (9.8 in)
50 years	302.0 mm (11.9 in)	Longer than the 30 years of record
100 years	365.6 mm (14.4 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 1939 to 1979.

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: 284.5 mm (11.2 in) in 1952; 240.0 mm (9.4 in) in 1943; 233.7 mm (9.2 in) in 1975.
