A day with at least 84.9 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 303.0 mm (11.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Novillero: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	84.9 mm (3.3 in)
5 years	117.7 mm (4.6 in)
10 years	147.1 mm (5.8 in)
25 years	196.1 mm (7.7 in)
50 years	243.7 mm (9.6 in)	Longer than the 32 years of record
100 years	303.0 mm (11.9 in)	Longer than the 32 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, 32 years of values from 1965 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: 333.8 mm (13.1 in) in 2005; 158.8 mm (6.3 in) in 2007; 143.3 mm (5.6 in) in 2006.
