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
32 years with a frostAcross 32 years with a frost, the median last spring frost at Patjens Oregon falls on 15 April and the median first autumn frost on 3 November, which leaves a median of 200 days between them.
