A year with missing days can understate an extreme.

Rainfall Return Levels

95 years, 1912 to 2018

A day with at least 29.5 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 76.5 mm (3.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Penneshaw: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	29.5 mm (1.2 in)
5 years	40.2 mm (1.6 in)
10 years	48.0 mm (1.9 in)
25 years	58.7 mm (2.3 in)
50 years	67.3 mm (2.6 in)
100 years	76.5 mm (3.0 in)	Longer than the 95 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, 95 years of values from 1912 to 2018.

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: 67.6 mm (2.7 in) in 1948; 64.8 mm (2.6 in) in 1941; 63.5 mm (2.5 in) in 1946.
