77° on Nov. 15, 1993, the hottest reading for this week of the year since 1963. Next is 72° in 2022.
Asharoken’s center stands about 10 ft above sea level. Within three miles the land runs from 0 ft to 200 ft, a difference of 200 ft: gently rolling country. Open water lies within three miles. The highest named summit within 15 miles is High Hill, about 420 ft, 8 miles south-southwest.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 52×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Clay, sand, gravel. Age: Late Cretaceous, 66 to 100 million years old. About 11 mi of the line.

Asharoken has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 25° in January. A normal year brings about 32 inches of snow; with the rain, that comes to about 46 inches of water.
On November 14 Asharoken normally reaches 54° and falls to 38°. The record high is 69°, in 1980; the record low 19°, in 1986. The most rain on this date, 2.61 in, fell in 1972.
