90° on Nov. 16, 2025, the hottest reading for this week of the year since 1911. Next is 87° in 2021.
Rule’s center stands about 1,680 ft above sea level. Within three miles the land runs from 1,580 ft to 1,690 ft, a difference of 110 ft: gently rolling country.
Under the town center the state geologic map shows Seymour Formation (conglomerate), from the Pleistocene, less than 2.6 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 64×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Claystone. Age: Permian, 252 to 299 million years old. About 6 mi of the line.
Coarse-detrital, fine-detrital. Age: Quaternary, less than 2.6 million years old. About 5 mi of the line.
Fine-detrital, coarse-detrital. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Sand. Age: Holocene, less than 12,000 years old. About 4 mi of the line.
Conglomerate. Age: Pleistocene, less than 2.6 million years old. About 3 mi of the line.
Sandstone-mudstone. Age: Permian, 252 to 299 million years old. About 1 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.
Rule has a humid subtropical climate. Summer afternoons average 97° in July; winter nights fall to about 30° in January. About 26 inches of rain fall in a normal year, with about 4 inches of snow.
On November 14 Rule normally reaches 66° and falls to 40°. The record high is 85°, in 2025; the record low 20°, in 2013. The most rain on this date, 1.89 in, fell in 1954.
Normals 1991–2020 and records since 1911 at Stamford 1, 17 miles south-southeast. NOAA, through RCC-ACIS.
