Expected about once in	A day with at least	Note
2 years	88.3 mm (3.5 in)
5 years	151.2 mm (6.0 in)
10 years	210.3 mm (8.3 in)
25 years	313.2 mm (12.3 in)
50 years	417.1 mm (16.4 in)
100 years	551.2 mm (21.7 in)	Longer than the 84 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, 84 years of values from 1907 to 2005.

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: 567.9 mm (22.4 in) in 1917; 482.6 mm (19.0 in) in 1974; 419.1 mm (16.5 in) in 1932.
