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
29 years with a frostAcross 29 years with a frost, the median last spring frost at Lake Minchumina Alaska falls on 15 May and the median first autumn frost on 17 September, which leaves a median of 123 days between them.

| Measure | Median, all years | Earliest period | Recent period (1995 to 2025) | Recent against earliest | Fitted trend |
|---|---|---|---|---|---|
| Last spring frost | 15 May | n/a | 15 May | n/a | +3.8 days per decade |
| First autumn frost | 17 September | n/a | 17 September | n/a | -1.9 days per decade |
