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
26 years with a frostAcross 26 years with a frost, the median last spring frost at Upernavik falls on 28 June and the median first autumn frost on 5 July, which leaves a median of 8 days between them.

| Measure | Median, all years | Earliest period | Recent period (1959 to 2001) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 28 June | n/a | 28 June | n/a | -1.4 days per decade |
| First autumn frost | 5 July | n/a | 5 July | n/a | +5.8 days per decade |
| Growing days | 8 days | n/a | 8 days | n/a | +7.2 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.
