The Strafford 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.
72° on Nov. 11, 2020, the hottest reading for this week of the year since 1950. Next is 70° in 2022.
Strafford’s center stands about 940 ft above sea level. Within three miles the land runs from 900 ft to 1,890 ft, a difference of 990 ft: steep hill country. The highest named summit within 15 miles is Michigan Hill, about 2,410 ft, 14 miles north.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 11×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Phyllite, limestone. Age: Silurian to Early Devonian, 394 to 425 million years old. About 19 mi of the line.
Mica-schist, quartzite. Age: Early Devonian, 394 to 422 million years old. About 4 mi of the line.
Gneiss, granofels, amphibolite. Age: Silurian to Early Devonian, 394 to 425 million years old. About 0.4 mi of the line.

A raindrop that lands in Strafford reaches Long Island Sound and the Atlantic Ocean by way of the West Branch Ompompanoosuc, the Ompompanoosuc and the Connecticut: about 240 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Strafford; river miles along the main stem, rounded.
Strafford has a warm-summer humid continental climate. Summer afternoons average 82° in July; winter nights fall to about 6° in January. About 40 inches of rain fall in a normal year.
