100 years
68.3 mm (2.7 in)
Longer than the 31 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, 31 years of values from 1949 to 1984.
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: 67.8 mm (2.7 in) in 1963; 57.4 mm (2.3 in) in 1968; 31.0 mm (1.2 in) in 1962.
