Each chart shows one value per year; the dot marks the record year. TXx is the hottest daily maximum, TNn the coldest daily minimum, Rx1day and Rx5day the largest one-day and five-day rain totals, and CDD the longest run of days with less than 1 mm of rain. A year with missing days can understate an extreme.

Rainfall Return Levels

83 years, 1936 to 2025

A day with at least 109.4 mm (4.3 in) of rain is expected about once in 2 years. A day with at least 268.2 mm (10.6 in) of rain is expected about once in 100 years.

Rainfall return levels at Rosman: the daily rain expected about once in a given number of years
Expected about once in	A day with at least	Note
2 years	109.4 mm (4.3 in)
5 years	147.8 mm (5.8 in)
10 years	174.8 mm (6.9 in)
25 years	210.9 mm (8.3 in)
50 years	239.0 mm (9.4 in)
100 years	268.2 mm (10.6 in)	Longer than the 83 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, 83 years of values from 1936 to 2025.

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: 332.7 mm (13.1 in) in 1964; 237.2 mm (9.3 in) in 1967; 215.1 mm (8.5 in) in 1973.
