Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Rainfall Return Levels

88 years, 1869 to 2022

A day with at least 38.6 mm (1.5 in) of rain is expected about once in 2 years. A day with at least 99.2 mm (3.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Mornington: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	38.6 mm (1.5 in)
5 years	52.2 mm (2.1 in)
10 years	62.1 mm (2.4 in)
25 years	76.0 mm (3.0 in)
50 years	87.2 mm (3.4 in)
100 years	99.2 mm (3.9 in)	Longer than the 88 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, 88 years of values from 1869 to 2022.

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: 108.0 mm (4.3 in) in 1934; 91.4 mm (3.6 in) in 1939; 81.3 mm (3.2 in) in 1887.
