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
84 years with a frostAcross 84 years with a frost, the median last spring frost at Sussex falls on 31 May and the median first autumn frost on 14 September, which leaves a median of 106 days between them.
In 1953 to 1983 the median growing season was 106 days. That is 4 days more than in 1899 to 1928.
Fitted over all years, the growing season changes by +0.5 days per decade at this station.
| Measure | Median, all years | Earliest period (1899 to 1928) | Recent period (1953 to 1983) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 31 May | 4 June | 31 May | 4 days earlier | -0.2 days per decade |
| First autumn frost | 14 September | 13 September | 14 September | 1 day later | +0.2 days per decade |
| Growing days | 106 days | 102 days | 106 days | 4 days more | +0.5 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
81 years, 1898 to 1983A day with at least 54.8 mm (2.2 in) of rain is expected about once in 2 years. A day with at least 118.3 mm (4.7 in) of rain is expected about once in 100 years.
| Expected about once in | A day with at least | Note |
|---|---|---|
| 2 years | 54.8 mm (2.2 in) | |
| 5 years | 71.7 mm (2.8 in) | |
| 10 years | 83.0 mm (3.3 in) | |
| 25 years | 97.2 mm (3.8 in) | |
| 50 years | 107.8 mm (4.2 in) | |
| 100 years | 118.3 mm (4.7 in) | Longer than the 81 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, 81 years of values from 1898 to 1983.
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: 98.8 mm (3.9 in) in 1962; 98.0 mm (3.9 in) in 1902; 97.3 mm (3.8 in) in 1909.
Station Changes
2 suspected2 changes were suspected in the annual mean temperature of Sussex, at 1930 and 1955. Each is measured against neighbouring stations.
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1930 ran 0.6 C (1.1 F) higher than in the years before (possible change).
- Relative to 5 neighbouring stations, the station's annual mean temperature from 1955 ran 0.6 C (1.0 F) lower than in the years before (likely change).
| Year | Shift (C) | Shift (F) | Strength | Neighbours |
|---|---|---|---|---|
| 1930 | +0.6 | +1.1 | possible | 5 |
| 1955 | -0.5 | -1.0 | likely | 5 |
Possible change at the station (a move, a new instrument or a new site); the record is kept as measured. A "likely" change has a larger test statistic than a "possible" one. Neither says why the station differs from its neighbours. How changes are found, and the largest ones.
