The Hansville plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
70° on Nov. 14, 1995, the hottest reading for this week of the year since 1894. Next is 66° in 1905.
Hansville’s center stands about 20 ft above sea level. Within three miles the land runs from 0 ft to 380 ft, a difference of 380 ft: rolling country. Open water lies within three miles. The highest named summit within 15 miles is Jorgenson Hill, about 410 ft, 11 miles northwest.
The section below crosses 2 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 29×. 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 12 mi of the line.

Rain that falls on Hansville runs straight into Puget Sound and the Pacific Ocean.

Hansville has a warm-summer Mediterranean climate. Summer afternoons average 77° in August; winter nights fall to about 37° in January. About 38 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Hansville normally reaches 52° and falls to 41°. The record high is 70°, in 1995; the record low 15°, in 1955. The most rain on this date, 2.27 in, fell in 1906.
