The line is the average temperature and the bars are average precipitation at Darrington RS, 7 miles from the center point at 550 feet, station USC00451992 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 83 inches a year. The station sits about 5,200 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
