Portland, Oregon – Spring 2026 could trend warmer and drier across Oregon, reducing late-season mountain snow and increasing early wildfire concerns before summer officially begins.
According to NOAA’s Seasonal Temperature and Precipitation Outlook released February 19, much of Oregon is favored to see above normal temperatures paired with below normal precipitation during March-April-May 2026. That combination signals more frequent mild to warm afternoons and fewer widespread Pacific storm systems through the heart of spring.
In Portland and the Willamette Valley, March may still bring passing rain systems, but overall rainfall totals could trend lighter than average. Warmer daytime highs may push into the 60s and 70s more often by April, with 80-degree readings possible in May. Reduced precipitation may also limit late-season snow accumulation in the Cascades, affecting snowpack levels heading into summer water planning.
Salem and Eugene may see similar trends, with longer dry stretches between frontal systems. In southern Oregon, including Medford and Klamath Falls, above normal warmth combined with limited rainfall could elevate fire weather risk during windy afternoons.
Eastern Oregon, including Bend, may experience accelerated snowmelt at mid-elevations, reducing additional moisture gains in mountain basins.
Overall, Oregon appears poised for a warmer and drier-than-average spring. Residents should prepare for earlier warm spells, declining snowpack gains and heightened wildfire concerns through May as the state transitions toward summer.
