A year with missing days can understate an extreme.

Rainfall Return Levels

48 years, 1965 to 2013

A day with at least 86.6 mm (3.4 in) of rain is expected about once in 2 years. A day with at least 187.9 mm (7.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Coonabarabran (Westmount): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	86.6 mm (3.4 in)
5 years	113.7 mm (4.5 in)
10 years	131.7 mm (5.2 in)
25 years	154.4 mm (6.1 in)
50 years	171.2 mm (6.7 in)	Longer than the 48 years of record
100 years	187.9 mm (7.4 in)	Longer than the 48 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, 48 years of values from 1965 to 2013.

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: 164.6 mm (6.5 in) in 1976; 157.5 mm (6.2 in) in 1971; 155.6 mm (6.1 in) in 1995.
