89° on Nov. 17, 2025, the hottest reading for this week of the year since 1918. Next is 87° in 1921.
Tolar’s center stands about 1,030 ft above sea level. Within three miles the land runs from 940 ft to 1,130 ft, a difference of 190 ft: gently rolling country. The highest named summit within 15 miles is Chalk Mountain, about 1,260 ft, 15 miles south.
Under the town center the state geologic map shows Glen Rose Limestone (limestone, marlstone), from the Early Cretaceous, 100 to 145 million years old.
The section below crosses 2 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, marlstone. Age: Early Cretaceous, 100 to 145 million years old. About 16 mi of the line.
Sandstone. Age: Early Cretaceous, 100 to 145 million years old. About 8 mi of the line.

A raindrop that lands in Tolar reaches the Gulf of America by way of Squaw Creek and the Brazos: about 530 river miles.
Lake on the way: Safe Shutdown Impoundment.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Tolar; river miles along the main stem, rounded.
Tolar has a humid subtropical climate. Summer afternoons average 98° in August; winter nights fall to about 31° in January. About 34 inches of rain fall in a normal year.
On November 14 Tolar normally reaches 69° and falls to 42°. The record high is 87°, in 1989; the record low 20°, in 1976. The most rain on this date, 1.43 in, fell in 1923.
