Rainfall Return Levels

35 years, 1979 to 2014

A day with at least 59.8 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 201.5 mm (7.9 in) of rain is expected about once in 100 years.

Rainfall return levels at Walpole 3: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	59.8 mm (2.4 in)
5 years	79.0 mm (3.1 in)
10 years	97.0 mm (3.8 in)
25 years	128.5 mm (5.1 in)
50 years	160.3 mm (6.3 in)	Longer than the 35 years of record
100 years	201.5 mm (7.9 in)	Longer than the 35 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, 35 years of values from 1979 to 2014.

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: 216.2 mm (8.5 in) in 2005; 134.6 mm (5.3 in) in 1999; 116.8 mm (4.6 in) in 2014.
