72° on Nov. 11, 2020, the hottest reading for this week of the year since 1926. Next is 71° in 2022.
Ludlow’s center stands about 250 ft above sea level. Within three miles the land runs from 160 ft to 570 ft, a difference of 410 ft: hilly country. The highest named summit within 15 miles is Mount Pisgah, about 1,270 ft, 13 miles east-southeast.
Under the town center the state geologic map shows Portland Formation (conglomerate, arkose), from the Early Jurassic, 175 to 202 million years old.
The section below crosses 8 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 20×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Conglomerate, arkose. Age: Early Jurassic, 175 to 202 million years old. About 12 mi of the line.
Hornblende-gneiss. Age: Devonian, 359 to 422 million years old. About 4 mi of the line.
Arkose, siltstone. Age: Early Jurassic, 175 to 202 million years old. About 3 mi of the line.
Biotite-gneiss, amphibolite. Age: Late Ordovician to Silurian, 440 to 454 million years old. About 2 mi of the line.
Quartz-monzodiorite. Age: Devonian, 359 to 422 million years old. About 2 mi of the line.
Gneiss. Age: Late Ordovician to Silurian, 440 to 454 million years old. About 0.7 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 2 smaller units 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 Ludlow reaches Long Island Sound and the Atlantic Ocean by way of Fuller Brook, the Chicopee and the Connecticut: about 90 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Ludlow; river miles along the main stem, rounded.
Ludlow has a hot-summer humid continental climate. Summer afternoons average 85° in July; winter nights fall to about 15° in January. About 45 inches of rain fall in a normal year.
On November 14 Ludlow normally reaches 51° and falls to 31°. The record high is 66°, in 2011; the record low 11°, in 2019. The most rain on this date, 1.44 in, fell in 1995.
Normals 1991–2020 and records since 1926 from the Westfield Area threaded record (Westfield-Barnes Regional Airport, 12 miles west). NOAA, through RCC-ACIS.
