A year with missing days can understate an extreme.

Rainfall Return Levels

46 years, 1935 to 1983

A day with at least 58.2 mm (2.3 in) of rain is expected about once in 2 years. A day with at least 149.3 mm (5.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Petrolandia (Itaparica): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	58.2 mm (2.3 in)
5 years	88.4 mm (3.5 in)
10 years	105.8 mm (4.2 in)
25 years	125.2 mm (4.9 in)
50 years	137.9 mm (5.4 in)	Longer than the 46 years of record
100 years	149.3 mm (5.9 in)	Longer than the 46 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, 46 years of values from 1935 to 1983.

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: 150.1 mm (5.9 in) in 1973; 117.6 mm (4.6 in) in 1981; 114.0 mm (4.5 in) in 1977.
