Rainfall Return Levels

42 years, 1923 to 1984

A day with at least 35.3 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 122.6 mm (4.8 in) of rain is expected about once in 100 years.

Rainfall return levels at Booroorban Post Office: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	35.3 mm (1.4 in)
5 years	51.7 mm (2.0 in)
10 years	64.9 mm (2.6 in)
25 years	84.8 mm (3.3 in)
50 years	102.4 mm (4.0 in)	Longer than the 42 years of record
100 years	122.6 mm (4.8 in)	Longer than the 42 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, 42 years of values from 1923 to 1984.

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: 114.3 mm (4.5 in) in 1950; 90.4 mm (3.6 in) in 1930; 78.0 mm (3.1 in) in 1974.
