A year with missing days can understate an extreme.

Rainfall Return Levels

47 years, 1959 to 2007

A day with at least 54.4 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 136.4 mm (5.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Somerton (Kallaroo): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	54.4 mm (2.1 in)
5 years	74.6 mm (2.9 in)
10 years	88.6 mm (3.5 in)
25 years	107.2 mm (4.2 in)
50 years	121.5 mm (4.8 in)	Longer than the 47 years of record
100 years	136.4 mm (5.4 in)	Longer than the 47 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, 47 years of values from 1959 to 2007.

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: 121.9 mm (4.8 in) in 1964; 107.0 mm (4.2 in) in 1991; 98.4 mm (3.9 in) in 1976.
