A year with missing days can understate an extreme.

Rainfall Return Levels

34 years, 1992 to 2025

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 34 years of values from 1992 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: 254.0 mm (10.0 in) in 2020; 238.0 mm (9.4 in) in 2017; 230.0 mm (9.1 in) in 2022.
