10 years	65.1 mm (2.6 in)
25 years	81.5 mm (3.2 in)
50 years	94.7 mm (3.7 in)
100 years	108.8 mm (4.3 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 100 years of values from 1888 to 1993.

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: 121.9 mm (4.8 in) in 1896; 93.7 mm (3.7 in) in 1895; 89.9 mm (3.5 in) in 1890.
