A day with at least 76.8 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 178.7 mm (7.0 in) of rain is expected about once in 100 years.

Rainfall return levels at Kolo 1033: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	76.8 mm (3.0 in)
5 years	107.5 mm (4.2 in)
10 years	126.4 mm (5.0 in)
25 years	148.7 mm (5.9 in)
50 years	164.2 mm (6.5 in)
100 years	178.7 mm (7.0 in)	Longer than the 57 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, 57 years of values from 1937 to 1995.

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: 168.4 mm (6.6 in) in 1940; 160.8 mm (6.3 in) in 1949; 151.9 mm (6.0 in) in 1975.
