2 years	49.1 mm (1.9 in)
5 years	66.1 mm (2.6 in)
10 years	79.1 mm (3.1 in)
25 years	97.9 mm (3.9 in)
50 years	113.7 mm (4.5 in)
100 years	131.3 mm (5.2 in)	Longer than the 88 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, 88 years of values from 1912 to 2024.

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: 160.0 mm (6.3 in) in 2021; 108.0 mm (4.3 in) in 1913; 95.3 mm (3.8 in) in 1921.
