3.51 inches of rain fell in two days, the most for this week of the year since records began in 1893. The next wettest, 3.04 inches, fell in 1975.
Methuen’s center stands about 120 ft above sea level. Within three miles the land runs from 30 ft to 270 ft, a difference of 240 ft: rolling country. The highest named summit within 15 miles is Warner Hill, about 620 ft, 12 miles north-northwest.
Under the town center the state geologic map shows Berwick Formation (metaclastic), from the Silurian, 422 to 445 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 37×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granofels, biotite-schist. Age: Ordovician to Silurian, 422 to 487 million years old. About 11 mi of the line.
Granite, pegmatite. Age: Ordovician to Silurian, 422 to 487 million years old. About 8 mi of the line.
Metaclastic. Age: Silurian, 422 to 445 million years old. About 4 mi of the line.
Tonalite, diorite. Age: Silurian, 425 to 435 million years old. About 2 mi of the line.
Granite. Age: Late Devonian, 359 to 384 million years old. About 0.3 mi of the line.

A raindrop that lands in Methuen reaches the Atlantic Ocean by way of World End Brook, the Spicket and the Merrimack: about 35 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Methuen; river miles along the main stem, rounded.
Methuen has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 20° in January. About 49 inches of rain fall in a normal year.
On November 14 Methuen normally reaches 51° and falls to 35°. The record high is 70°, in 1959; the record low 12°, in 1905. The most rain on this date, 2.75 in, fell in 1937.
Normals 1991–2020 and records since 1893 at Lawrence, 2 miles southeast. NOAA, through RCC-ACIS.
