A year with missing days can understate an extreme.

Rainfall Return Levels

47 years, 1945 to 1991

A day with at least 29.2 mm (1.1 in) of rain is expected about once in 2 years. A day with at least 72.2 mm (2.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Robertstown (Geranium Plains): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.2 mm (1.1 in)
5 years	41.4 mm (1.6 in)
10 years	49.2 mm (1.9 in)
25 years	58.8 mm (2.3 in)
50 years	65.6 mm (2.6 in)	Longer than the 47 years of record
100 years	72.2 mm (2.8 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 1945 to 1991.

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: 75.7 mm (3.0 in) in 1946; 56.4 mm (2.2 in) in 1973; 55.9 mm (2.2 in) in 1961.
