A year with missing days can understate an extreme.

Rainfall Return Levels

80 years, 1915 to 2021

A day with at least 25.6 mm (1.0 in) of rain is expected about once in 2 years. A day with at least 87.7 mm (3.5 in) of rain is expected about once in 100 years.

Rainfall return levels at Lock: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	25.6 mm (1.0 in)
5 years	36.2 mm (1.4 in)
10 years	45.1 mm (1.8 in)
25 years	59.2 mm (2.3 in)
50 years	72.2 mm (2.8 in)
100 years	87.7 mm (3.5 in)	Longer than the 80 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, 80 years of values from 1915 to 2021.

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: 94.0 mm (3.7 in) in 1938; 82.6 mm (3.3 in) in 1917; 69.3 mm (2.7 in) in 1946.
