77° on Nov. 16, 2008, the hottest reading for this week of the year since 1971. Next is 74° in 1974.
Coquille’s center stands about 70 ft above sea level. Within three miles the land runs from 0 ft to 900 ft, a difference of 900 ft: hilly country. The highest named summit within 15 miles is Sheeps Head, about 2,370 ft, 13 miles east-southeast.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 15×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone. Age: Middle Eocene to Late Eocene, 34 to 48 million years old. About 13 mi of the line.
Sandstone. Age: Middle Eocene, 38 to 48 million years old. About 7 mi of the line.
Gravel, boulders, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone. Age: Paleocene to Early Eocene, 48 to 66 million years old. About 1 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.7 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 0.5 mi of the line.

A raindrop that lands in Coquille reaches the Pacific Ocean by way of Cunningham Creek and the Coquille: about 25 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Coquille; river miles along the main stem, rounded.
Coquille has a warm-summer Mediterranean climate. Summer afternoons average 74° in August; winter nights fall to about 36° in December. About 55 inches of rain fall in a normal year.
On November 14 Coquille normally reaches 59° and falls to 40°. The record high is 73°, in 1995; the record low 18°, in 1978. The most rain on this date, 1.78 in, fell in 1981.
