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
21 years with a frostAcross 21 years with a frost, the median last spring frost at Slana falls on 14 June and the median first autumn frost on 17 August, which leaves a median of 65 days between them.
| Measure | Median, all years | Earliest period | Recent period (1958 to 1998) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 14 June | n/a | 14 June | n/a | n/a |
| First autumn frost | 17 August | n/a | 17 August | n/a | n/a |
| Growing days | 65 days | n/a | 65 days | n/a | n/a |
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.
