In late June, Portland International Airport set a new all-time high temperature record (pink dots) three days in a row. Not only was this record much warmer than the average high from 1991-2020 (top of the dark gray area), it was well outside the margin of other daily records (light gray). The most extreme heat occurred on June 28, when the daytime maximum temperature reached 116 degrees Fahrenheit, blowing past the previous record of 100 degrees.
