A year with missing days can understate an extreme.

Rainfall Return Levels

36 years, 1933 to 1971

A day with at least 43.0 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 83.9 mm (3.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Forest (van Diemans Land Compa: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	43.0 mm (1.7 in)
5 years	54.4 mm (2.1 in)
10 years	61.8 mm (2.4 in)
25 years	70.9 mm (2.8 in)
50 years	77.5 mm (3.1 in)	Longer than the 36 years of record
100 years	83.9 mm (3.3 in)	Longer than the 36 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, 36 years of values from 1933 to 1971.

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: 75.4 mm (3.0 in) in 1969; 68.6 mm (2.7 in) in 1946; 66.5 mm (2.6 in) in 1953.
