Rainfall Return Levels

38 years, 1943 to 1986

A day with at least 75.5 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 101.2 mm (4.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Sumidouro-Usina Sao Jorge: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	75.5 mm (3.0 in)
5 years	87.4 mm (3.4 in)
10 years	92.6 mm (3.6 in)
25 years	97.1 mm (3.8 in)
50 years	99.5 mm (3.9 in)	Longer than the 38 years of record
100 years	101.2 mm (4.0 in)	Longer than the 38 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, 38 years of values from 1943 to 1986.

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: 104.6 mm (4.1 in) in 1946; 104.0 mm (4.1 in) in 1984; 90.7 mm (3.6 in) in 1957.
