15° on Nov. 15, 1955, the coldest reading for this week of the year since 1899. Next is 19° in 1961.
Winston’s center stands about 540 ft above sea level. Within three miles the land runs from 480 ft to 1,380 ft, a difference of 900 ft: hilly country. The highest named summit within 15 miles is Nickel Mountain, about 3,480 ft, 11 miles south.
Under the town center the state geologic map shows Sedimentary rocks of Dothan Formation and related rocks (mudstone, sandstone), from the Late Jurassic to Late Cretaceous, 66 to 164 million years old.
The section below crosses 7 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 8×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Sand, gravel, silt. Age: Holocene, less than 12,000 years old. About 7 mi of the line.
Mudstone, sandstone. Age: Late Jurassic to Late Cretaceous, 66 to 164 million years old. About 6 mi of the line.
Basalt. Age: Paleocene to Middle Eocene, 38 to 66 million years old. About 3 mi of the line.
Graywacke, mudstone. Age: Late Jurassic, 145 to 153 million years old. About 3 mi of the line.
Sandstone. Age: Paleocene to Early Eocene, 48 to 66 million years old. About 2 mi of the line.
Siltstone, sandstone. Age: Late Jurassic to Early Cretaceous, 125 to 153 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 1 smaller unit along the line are not listed.

A raindrop that lands in Winston reaches the Pacific Ocean by way of the South Umpqua and the Umpqua: about 130 river miles.
110 miles of the trip are on the Umpqua.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Winston; river miles along the main stem, rounded.
Winston has a warm-summer Mediterranean climate. Summer afternoons average 86° in July; winter nights fall to about 37° in January. About 32 inches of rain fall in a normal year.
On November 14 Winston normally reaches 54° and falls to 41°. The record high is 68°, in 2001; the record low 17°, in 1955. The most rain on this date, 2.01 in, fell in 1941.
Normals 1991–2020 and records since 1899 at Roseburg Regional Airport, 8 miles north-northeast. NOAA, through RCC-ACIS.
