A day with at least 52.9 mm (2.1 in) of rain is expected about once in 2 years. A day with at least 143.5 mm (5.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Qacu (Bos): the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	52.9 mm (2.1 in)
5 years	72.5 mm (2.9 in)
10 years	87.1 mm (3.4 in)
25 years	107.8 mm (4.2 in)
50 years	124.9 mm (4.9 in)
100 years	143.5 mm (5.6 in)

The levels come from a generalised extreme value (GEV) distribution fitted by L-moments to the wettest-day total of each year, 101 years of values from 1888 to 1991.

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: 172.5 mm (6.8 in) in 1891; 125.7 mm (4.9 in) in 1917; 112.8 mm (4.4 in) in 1985.
