A year with missing days can understate an extreme.

Rainfall Return Levels

48 years, 1955 to 2005

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 205.8 mm (8.1 in) of rain is expected about once in 100 years.

Rainfall return levels at Nullamanna (Severn Vale): 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	81.7 mm (3.2 in)
10 years	102.2 mm (4.0 in)
25 years	135.6 mm (5.3 in)
50 years	167.2 mm (6.6 in)	Longer than the 48 years of record
100 years	205.8 mm (8.1 in)	Longer than the 48 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, 48 years of values from 1955 to 2005.

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: 180.0 mm (7.1 in) in 1978; 175.3 mm (6.9 in) in 1956; 148.6 mm (5.9 in) in 1955.
