77° on Nov. 14, 1999, the hottest reading for this week of the year since 1899. Next is 76° in 2012.
Livermore’s center stands about 1,140 ft above sea level. Within three miles the land runs from 1,080 ft to 1,160 ft, a difference of 80 ft: gently rolling country.
The section below crosses 4 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.
Sandstone, shale. Age: Early Cretaceous to Late Cretaceous, 94 to 113 million years old. About 20 mi of the line.
Dolostone, limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 2 mi of the line.
Dolostone, limestone, siltstone. Age: Early Mississippian, 347 to 359 million years old. About 1 mi of the line.
Limestone. Age: Early Mississippian to Middle Mississippian, 331 to 359 million years old. About 1 mi of the line.

A raindrop that lands in Livermore reaches the Gulf of America by way of Lotts Creek, the Des Moines and the Mississippi: about 1,680 river miles.
Lakes on the way: Roberts Creek and Big Creek Pounding Area.
1,330 miles of the trip are on the Mississippi.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Livermore; river miles along the main stem, rounded.
Livermore has a hot-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 8° in January. A normal year brings about 39 inches of snow; with the rain, that comes to about 35 inches of water.
On November 14 Livermore normally reaches 46° and falls to 26°. The record high is 77°, in 1999; the record low −6°, in 1959. The most rain on this date, 1.35 in, fell in 1909.
Normals 1991–2020 and records since 1899 at Fort Dodge 5 NNW, 20 miles south. NOAA, through RCC-ACIS.
