Portland International Airport set a new daily high temperature record of 91 degrees on May 4, 2026. This surpassed the previous record of 89 degrees, which was established in 1992.
A heat advisory remains in effect for the immediate Portland metropolitan area through 11 PM Sunday night. The unusually high temperatures are part of a larger pattern, with current readings about 10 degrees above average for this time of year.
Temperatures peaked at 91 degrees around 4 PM. The warm weather is expected to continue into Mother’s Day weekend, with no significant rain forecasted.
This spike in temperature has drawn attention from local meteorologists and residents alike. Many are enjoying the afternoon sunshine, but caution is advised due to the ongoing heat advisory.
Temperatures are projected to fall back into the 70s later this week. However, the current heat wave has prompted discussions about climate patterns and their potential impacts on local weather.
