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.
Frost Dates and Growing Season
60 years with a frostAcross 60 years with a frost, the median last spring frost at Dulan falls on 21 May and the median first autumn frost on 21 September, which leaves a median of 119 days between them.
In 1985 to 2021 the median growing season was 120 days. That is 1 day more than in 1955 to 1984.
Fitted over all years, the growing season changes by +2.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1955 to 1984) | Recent period (1985 to 2021) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 21 May | 24 May | 21 May | 3 days earlier | -1.3 days per decade |
| First autumn frost | 21 September | 20 September | 22 September | 2 days later | +1.2 days per decade |
| Growing days | 119 days | 119 days | 120 days | 1 day more | +2.5 days per decade |
A frost day is a day with a daily minimum at or below 0 C (32 F). The last spring frost and the first autumn frost are the last and first such days of the cold season, and growing days are the days between them. A negative trend for the last spring frost means it comes earlier.
Rainfall Return Levels
61 years, 1954 to 2021A day with at least 19.7 mm (0.8 in) of rain is expected about once in 2 years. A day with at least 48.4 mm (1.9 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 19.7 mm (0.8 in) | |
| 5 years | 26.1 mm (1.0 in) | |
| 10 years | 30.9 mm (1.2 in) | |
| 25 years | 37.4 mm (1.5 in) | |
| 50 years | 42.7 mm (1.7 in) | |
| 100 years | 48.4 mm (1.9 in) | Longer than the 61 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, 61 years of values from 1954 to 2021.
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: 55.1 mm (2.2 in) in 2021; 43.5 mm (1.7 in) in 2010; 42.5 mm (1.7 in) in 2009.
