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

79 years, 1888 to 1977

A day with at least 83.5 mm (3.3 in) of rain is expected about once in 2 years. A day with at least 210.8 mm (8.3 in) of rain is expected about once in 100 years.

Rainfall return levels at Redbank Post Office: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	83.5 mm (3.3 in)
5 years	115.3 mm (4.5 in)
10 years	137.2 mm (5.4 in)
25 years	166.0 mm (6.5 in)
50 years	188.2 mm (7.4 in)
100 years	210.8 mm (8.3 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 1888 to 1977.

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: 248.9 mm (9.8 in) in 1908; 185.2 mm (7.3 in) in 1947; 167.1 mm (6.6 in) in 1910.
