Rainfall return levels at Wowan 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	79.4 mm (3.1 in)
5 years	110.4 mm (4.3 in)
10 years	133.3 mm (5.2 in)
25 years	165.2 mm (6.5 in)
50 years	191.3 mm (7.5 in)
100 years	219.5 mm (8.6 in)	Longer than the 89 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, 89 years of values from 1922 to 2024.

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: 228.0 mm (9.0 in) in 2003; 220.0 mm (8.7 in) in 2010; 211.8 mm (8.3 in) in 1990.
