Expected about once in	A day with at least	Note
2 years	40.3 mm (1.6 in)
5 years	54.5 mm (2.1 in)
10 years	64.9 mm (2.6 in)
25 years	79.2 mm (3.1 in)
50 years	90.8 mm (3.6 in)	Longer than the 31 years of record
100 years	103.1 mm (4.1 in)	Longer than the 31 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, 31 years of values from 1969 to 2012.

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: 93.5 mm (3.7 in) in 2012; 70.9 mm (2.8 in) in 1980; 66.3 mm (2.6 in) in 2002.
