Rainfall Return Levels

47 years, 1978 to 2025

A day with at least 42.4 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 93.9 mm (3.7 in) of rain is expected about once in 100 years.

Rainfall return levels at Westbury (Birralee Road): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	42.4 mm (1.7 in)
5 years	55.8 mm (2.2 in)
10 years	64.8 mm (2.6 in)
25 years	76.4 mm (3.0 in)
50 years	85.1 mm (3.4 in)	Longer than the 47 years of record
100 years	93.9 mm (3.7 in)	Longer than the 47 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, 47 years of values from 1978 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: 79.2 mm (3.1 in) in 1998; 78.6 mm (3.1 in) in 1989; 72.3 mm (2.8 in) in 2022.
