Seattle's coldest days are getting warmer

Seattle's average coldest temperatures have risen by 3. 7°F from 1995-2024 compared to 1951-1980, according to an analysis from Climate Central. The research, which utilized data from NOAA's Regional Climate Centers, found that 97% of the 243 locations studied experienced similar warming trends. The implications of this increase could drastically change local ecosystems, affecting plant and insect populations. In addition to warmer coldest days, the Seattle area is witnessing more frequent extreme heat events, further complicating climate impacts.

Boise, Idaho, recorded the highest increase in the Northwest at 6. 9°F, followed closely by Bend, Oregon, and Lewiston, Idaho. This data highlights the urgent need for climate adaptation strategies at both local and regional levels. Understanding these changes is crucial for managing the impacts on agriculture, urban planning, and public health. The findings emphasize the necessity for communities to prepare for a changing climate.
