Expected about once in	A day with at least	Note
2 years	70.2 mm (2.8 in)
5 years	98.0 mm (3.9 in)
10 years	114.6 mm (4.5 in)
25 years	133.9 mm (5.3 in)
50 years	147.0 mm (5.8 in)
100 years	159.2 mm (6.3 in)	Longer than the 74 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, 74 years of values from 1913 to 2022.

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: 138.6 mm (5.5 in) in 1976; 138.0 mm (5.4 in) in 1994; 134.6 mm (5.3 in) in 1941.
