A year with missing days can understate an extreme.

Rainfall Return Levels

50 years, 1970 to 2019

A day with at least 38.8 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 81.2 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Murchison (Arcadia (Sunnyville: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	38.8 mm (1.5 in)
5 years	51.4 mm (2.0 in)
10 years	59.2 mm (2.3 in)
25 years	68.5 mm (2.7 in)
50 years	75.0 mm (3.0 in)
100 years	81.2 mm (3.2 in)	Longer than the 50 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, 50 years of values from 1970 to 2019.

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: 76.2 mm (3.0 in) in 1998; 71.0 mm (2.8 in) in 2017; 68.0 mm (2.7 in) in 1991.
