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
64 years, 1901 to 1967A day with at least 75.7 mm (3.0 in) of rain is expected about once in 2 years. A day with at least 248.1 mm (9.8 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 75.7 mm (3.0 in) | |
| 5 years | 107.2 mm (4.2 in) | |
| 10 years | 132.9 mm (5.2 in) | |
| 25 years | 172.3 mm (6.8 in) | |
| 50 years | 207.3 mm (8.2 in) | |
| 100 years | 248.1 mm (9.8 in) | Longer than the 64 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, 64 years of values from 1901 to 1967.
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: 306.3 mm (12.1 in) in 1915; 254.0 mm (10.0 in) in 1938; 158.0 mm (6.2 in) in 1942.
