Rainfall return levels at Hamersley: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	61.9 mm (2.4 in)
5 years	97.2 mm (3.8 in)
10 years	125.0 mm (4.9 in)
25 years	166.3 mm (6.5 in)
50 years	202.0 mm (8.0 in)
100 years	242.4 mm (9.5 in)	Longer than the 79 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, 79 years of values from 1912 to 2007.

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: 239.0 mm (9.4 in) in 1975; 207.0 mm (8.1 in) in 1945; 184.4 mm (7.3 in) in 1961.
