77° on Nov. 13, 1999, the hottest reading for this week of the year since 1970. Next is 73° in 1995.
Shady Cove’s center stands about 1,410 ft above sea level. Within three miles the land runs from 1,360 ft to 2,800 ft, a difference of 1,440 ft: steep hill country. The highest named summit within 15 miles is Olson Mountain, about 5,060 ft, 15 miles east-northeast.
Under the town center the state geologic map shows Alluvial deposits (sand, gravel, silt), from the Holocene, less than 12,000 years old.
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 6×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Basalt, basaltic-andesite. Age: Oligocene to Miocene, 5.3 to 34 million years old. About 15 mi of the line.
Basalt, basaltic-andesite. Age: Oligocene to Miocene, 5.3 to 34 million years old. About 4 mi of the line.
Volcanic. Age: Tertiary, 2.6 to 66 million years old. About 2 mi of the line.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Gravel, boulders, clay. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.9 mi of the line.
Andesite, hypabyssal-basalt, hypabyssal-basaltic-andesite. Age: Miocene, 5.3 to 23 million years old. About 0.4 mi of the line.

A raindrop that lands in Shady Cove reaches the Pacific Ocean by way of the Rogue: about 140 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Shady Cove; river miles along the main stem, rounded.
Shady Cove has a warm-summer Mediterranean climate. Summer afternoons average 90° in July; winter nights fall to about 31° in January. About 33 inches of rain fall in a normal year, with about 1 inch of snow.
On November 14 Shady Cove normally reaches 55° and falls to 34°. The record high is 73°, in 2025; the record low 11°, in 1978. The most rain on this date, 1.03 in, fell in 2024.
Normals 1991–2020 and records since 1970 at Lost Creek Dam, 8 miles east-northeast, 170 ft higher. NOAA, through RCC-ACIS.
