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
63 years with a frostAcross 63 years with a frost, the median last spring frost at Kastamonu falls on 23 April and the median first autumn frost on 24 October, which leaves a median of 184 days between them.
In 1973 to 2012 the median growing season was 184 days. The two periods have the same number of growing days.
Fitted over all years, the growing season changes by +0.4 days per decade at this station.
| Measure | Median, all years | Earliest period (1930 to 1968) | Recent period (1973 to 2012) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 23 April | 22 April | 27 April | 5 days later | 0.0 days per decade |
| First autumn frost | 24 October | 23 October | 27 October | 4 days later | +0.3 days per decade |
| Growing days | 184 days | 184 days | 184 days | no change | +0.4 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.
