74° on Nov. 14, 1999, the hottest reading for this week of the year since 1938. Next is 72° in 2022.
Gillford’s center stands about 1,050 ft above sea level. Within three miles the land runs from 930 ft to 1,140 ft, a difference of 210 ft: rolling country.
Under the town center the state geologic map shows Lower Ordovician (dolostone, sandstone), from the Early Ordovician, 471 to 487 million years old.
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 39×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Dolostone, sandstone. Age: Early Ordovician, 471 to 487 million years old. About 21 mi of the line.
Sandstone, siltstone, shale. Age: Middle Cambrian to Cambrian, 487 to 521 million years old. About 2 mi of the line.
Sandstone. Age: Cambrian, 487 to 542 million years old. About 0.8 mi of the line.
Sandstone, siltstone, shale. Age: Cambrian, 487 to 497 million years old. About 0.3 mi of the line.

A raindrop that lands in Gillford reaches the Gulf of America by way of Spring Creek, the Zumbro and the Mississippi: about 1,770 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Gillford; river miles along the main stem, rounded.
Gillford has a warm-summer humid continental climate. Summer afternoons average 83° in July; winter nights fall to about 4° in January. A normal year brings about 48 inches of snow; with the rain, that comes to about 36 inches of water.
On November 14 Gillford normally reaches 44° and falls to 25°. The record high is 74°, in 1999; the record low 3°, in 1996. The most rain on this date, 0.69 in, fell in 1951.
Normals 1991–2020 and records since 1938 at Theilman 1 SSW, 9 miles east-southeast, 300 ft lower. NOAA, through RCC-ACIS.
