When is peak fall foliage at Umatilla National Forest in 2026?
Our forecast puts peak color at Umatilla National Forest around Oct 20, and the four days to aim for are Oct 19 to 22.
The forest runs from about 2,046 to 5,695 feet, and the color comes downhill over about 12 days: the high stands around Oct 5, the low ground around Oct 9. That's 5 days later than our model alone would say, because this season's reports from the ground moved it.

Height off 3DEP inside the forest’s own boundary; each band carries the date our model gives that elevation, corrections and all. The percentage is how much of the forest stands in it.
That’s 5 days later than our model alone would say. This season’s reports from the ground moved it, and they outrank us.

This forecast is built from the species that stand here, their elevation and this September’s weather, and corrected in season by cameras, foresters and our own crew. Out here we score it against NASA's satellite record of when the canopy shuts down, read inside each unit’s own boundary: two dates in three land within 12 days of it. How this map is made
