95° on Nov. 13, 2007, the hottest reading for this week of the year since 1989. Next is 95° in 2016.
La Habra Heights’s center stands about 650 ft above sea level. Within three miles the land runs from 250 ft to 1,210 ft, a difference of 960 ft: steep hill country. The highest named summit within 15 miles is San Juan Hill, about 1,740 ft, 13 miles east-southeast.
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 14×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 10 mi of the line.
Sandstone, mudstone. Age: Oligocene to Pliocene, 2.6 to 34 million years old. About 10 mi of the line.
Coarse-detrital. Age: Pleistocene, less than 2.6 million years old. About 2 mi of the line.
Sandstone, mudstone. Age: Miocene to Pleistocene, less than 23 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
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.
A raindrop that lands in La Habra Heights reaches the Pacific Ocean by way of La Mirada Creek, Coyote Creek and the San Gabriel: about 20 river miles.
Often dry. About 80% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of La Habra Heights; river miles along the main stem, rounded.
La Habra Heights has a hot semi-arid climate. Summer afternoons average 89° in August; winter nights fall to about 48° in December. About 14 inches of rain fall in a normal year.
On November 14 La Habra Heights normally reaches 77° and falls to 53°. The record high is 94°, in 2007; the record low 39°, in 2000. The most rain on this date, 0.86 in, fell in 2025.
Normals 1991–2020 and records since 1989 at Anaheim, 9 miles southeast, 420 ft lower. NOAA, through RCC-ACIS.
