A day with at least 62.0 mm (2.4 in) of rain is expected about once in 2 years. A day with at least 156.4 mm (6.2 in) of rain is expected about once in 100 years.

Rainfall return levels at Mather: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	62.0 mm (2.4 in)
5 years	82.1 mm (3.2 in)
10 years	97.2 mm (3.8 in)
25 years	118.8 mm (4.7 in)
50 years	136.8 mm (5.4 in)	Longer than the 49 years of record
100 years	156.4 mm (6.2 in)	Longer than the 49 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, 49 years of values from 1954 to 2010.

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: 165.1 mm (6.5 in) in 1955; 120.9 mm (4.8 in) in 1996; 109.0 mm (4.3 in) in 1962.
