66° on Nov. 11, 2020, the hottest reading for this week of the year since 1996. Next is 63° in 2002.
Madawaska’s center stands about 1,010 ft above sea level. Within three miles the land runs from 580 ft to 1,150 ft, a difference of 570 ft: hilly country. The highest named summit within 15 miles is Glass Hill, about 1,270 ft, 11 miles west-southwest.
Under the town center the state geologic map shows Devonian - Silurian unnamed sedimentary rocks (sandstone, mudstone), from the Silurian to Devonian, 359 to 445 million years old.
The section below crosses 6 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 21×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Mudstone, sandstone. Age: Early Devonian, 410 to 414 million years old. About 6 mi of the line.
Sandstone, mudstone. Age: Silurian to Devonian, 359 to 445 million years old. About 5 mi of the line.
Mudstone, sandstone. Age: Ordovician, 445 to 487 million years old. About 4 mi of the line.
Mudstone, sandstone. Age: Silurian, 422 to 445 million years old. About 2 mi of the line.
Mudstone. Age: Silurian, 422 to 445 million years old. About 1 mi of the line.
Siltstone, limestone. Age: Late Ordovician to Silurian, 434 to 459 million years old. About 0.6 mi of the line.

A raindrop that lands in Madawaska reaches the Bay of Fundy and the Atlantic Ocean by way of Big Brook, the Little River, the Fish and the Saint John: about 320 river miles.
Lakes on the way: Square Lake and Long Lake.
270 miles of the trip are on the Saint John.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Madawaska; river miles along the main stem, rounded.
Madawaska has a warm-summer humid continental climate. Summer afternoons average 76° in July; winter nights fall to about 3° in January. About 33 inches of rain fall in a normal year.
On November 14 Madawaska normally reaches 39° and falls to 26°. The record high is 54°, in 2006; the record low 5°, in 2019. The most rain on this date, 1.49 in, fell in 2006.
Normals 1991–2020 and records since 1996 at Frenchville Northern Aroostook Airport, 3 miles west-southwest. NOAA, through RCC-ACIS.
