13° on Nov. 17, 1959, the coldest reading for this week of the year since 1872. Next is 15° in 1986.
Laconia’s center stands about 650 ft above sea level. Within three miles the land runs from 400 ft to 740 ft, a difference of 340 ft: rolling country. The highest named summit within 15 miles is Bee Knob Hill, about 1,010 ft, 12 miles south.
Under the town center the state geologic map shows Blue River Group (limestone), from the Carboniferous, 324 to 359 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 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.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 12 mi of the line.
Sand, silt. Age: Pleistocene to Holocene, less than 2.6 million years old. About 3 mi of the line.
Siltstone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Limestone. Age: Carboniferous, 324 to 359 million years old. About 2 mi of the line.
Sandstone. Age: Carboniferous, 324 to 359 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. 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.
Laconia has a humid subtropical climate. Summer afternoons average 89° in July; winter nights fall to about 28° in January. A normal year brings about 13 inches of snow; with the rain, that comes to about 48 inches of water.
On November 14 Laconia normally reaches 58° and falls to 40°. The record high is 79°, in 1902; the record low 15°, in 1986. The most rain on this date, 1.44 in, fell in 1929.
Normals 1991–2020 and records since 1872 from the Louisville Area threaded record (Louisville International Airport, 22 miles east-northeast, 170 ft lower). NOAA, through RCC-ACIS.
