Rainfall Return Levels

45 years, 1980 to 2025

A day with at least 35.7 mm (1.4 in) of rain is expected about once in 2 years. A day with at least 81.9 mm (3.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Adelaide (Hope Valley Reservoi: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	35.7 mm (1.4 in)
5 years	46.6 mm (1.8 in)
10 years	54.4 mm (2.1 in)
25 years	64.9 mm (2.6 in)
50 years	73.2 mm (2.9 in)	Longer than the 45 years of record
100 years	81.9 mm (3.2 in)	Longer than the 45 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, 45 years of values from 1980 to 2025.

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: 84.2 mm (3.3 in) in 2014; 66.4 mm (2.6 in) in 2016; 59.0 mm (2.3 in) in 1985.
