67° on Nov. 12, 1999, the hottest reading for this week of the year since 1881. Next is 65° in 1899.
Fairwood’s center stands about 1,820 ft above sea level. Within three miles the land runs from 1,560 ft to 2,420 ft, a difference of 860 ft: hilly country. The highest named summit within 15 miles is Krell Hill, about 3,670 ft, 14 miles south-southeast.
Under the town center the state geologic map shows Younger glacial drift (fine-detrital, coarse-detrital), from the Pleistocene, less than 2.6 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 12×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Fine-detrital, coarse-detrital. Age: Late Pliocene to Pleistocene, less than 3.6 million years old. About 10 mi of the line.
Basalt. Age: Late Oligocene to Early Pliocene, 3.6 to 28 million years old. About 7 mi of the line.
Granite. Age: Precambrian to Eocene. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Siltstone, sandstone. Age: Middle Miocene to Early Pliocene, 3.6 to 16 million years old. About 2 mi of the line.

A raindrop that lands in Fairwood reaches the Pacific Ocean by way of the Little Spokane, the Spokane and the Columbia: about 700 river miles.
Lake on the way: Lake Umatilla.
360 miles of the trip are on the Columbia.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Fairwood; river miles along the main stem, rounded.
Fairwood has a dry-summer warm-summer continental climate. Summer afternoons average 84° in July; winter nights fall to about 24° in December. A normal year brings about 45 inches of snow; with the rain, that comes to about 16 inches of water.
On November 14 Fairwood normally reaches 43° and falls to 31°. The record high is 65°, in 1899; the record low −7°, in 1955. The most rain on this date, 0.74 in, fell in 1966.
