70° on Nov. 13, 2013, the hottest reading for this week of the year since 1945. Next is 65° in 1990.
Stanwood’s center stands about 7 ft above sea level. Within three miles the land runs from 0 ft to 270 ft, a difference of 270 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Stimson Hill, about 2,890 ft, 14 miles east-northeast.
Under the town center the state geologic map shows Alluvium (silt, sand), from the Holocene, less than 12,000 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 16×. 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: Pleistocene, less than 2.6 million years old. About 7 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 4 mi of the line.
Arkose. Age: Late Cretaceous to Eocene, 34 to 100 million years old. About 3 mi of the line.
Fine-detrital, coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Silt, sand. Age: Holocene, less than 12,000 years old. About 2 mi of the line.
Metasedimentary. Age: Devonian to Permian, 273 to 422 million years old. About 0.4 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.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Stanwood reaches the Pacific Ocean by way of the West Pass: about 2 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Stanwood; river miles along the main stem, rounded.
Stanwood has a warm-summer Mediterranean climate. Summer afternoons average 70° in August; winter nights fall to about 37° in February. A normal year brings about 5 inches of snow; with the rain, that comes to about 20 inches of water.
On November 14 Stanwood normally reaches 54° and falls to 41°. The record high is 66°, in 2013; the record low 11°, in 1955. The most rain on this date, 0.70 in, fell in 2015.
Normals 1991–2020 and records since 1945 at Whidbey Island Nas, 16 miles west-northwest. NOAA, through RCC-ACIS.
