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
33 years with a frostAcross 33 years with a frost, the median last spring frost at Dover falls on 10 May and the median first autumn frost on 4 October, which leaves a median of 145 days between them.
Fitted over all years, the growing season changes by -8.2 days per decade at this station.
| Measure | Median, all years | Earliest period | Recent period (1899 to 1935) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 10 May | n/a | 10 May | n/a | +5.9 days per decade |
| First autumn frost | 4 October | n/a | 6 October | n/a | -2.3 days per decade |
| Growing days | 145 days | n/a | 145 days | n/a | -8.2 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.
