A day with at least 43.9 mm (1.7 in) of rain is expected about once in 2 years. A day with at least 167.9 mm (6.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Tshane: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	43.9 mm (1.7 in)
5 years	68.6 mm (2.7 in)
10 years	88.0 mm (3.5 in)
25 years	116.3 mm (4.6 in)
50 years	140.6 mm (5.5 in)	Longer than the 34 years of record
100 years	167.9 mm (6.6 in)	Longer than the 34 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, 34 years of values from 1959 to 1992.

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: 149.6 mm (5.9 in) in 1966; 110.0 mm (4.3 in) in 1976; 105.0 mm (4.1 in) in 1968.
