A day with at least 30.7 mm (1.2 in) of rain is expected about once in 2 years. A day with at least 85.3 mm (3.4 in) of rain is expected about once in 100 years.

Rainfall return levels at Bastorp: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	30.7 mm (1.2 in)
5 years	39.9 mm (1.6 in)
10 years	47.7 mm (1.9 in)
25 years	60.1 mm (2.4 in)
50 years	71.6 mm (2.8 in)	Longer than the 31 years of record
100 years	85.3 mm (3.4 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 1965 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: 72.9 mm (2.9 in) in 1981; 65.7 mm (2.6 in) in 1994; 53.2 mm (2.1 in) in 1988.
