2 years	60.6 mm (2.4 in)
5 years	81.1 mm (3.2 in)
10 years	98.4 mm (3.9 in)
25 years	125.5 mm (4.9 in)
50 years	150.3 mm (5.9 in)
100 years	179.7 mm (7.1 in)	Longer than the 75 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, 75 years of values from 1949 to 2025.

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: 165.1 mm (6.5 in) in 2015; 161.3 mm (6.4 in) in 1960; 149.1 mm (5.9 in) in 1958.
