Heat in Coalinga - Avenal, California

Daytime highs generally ranged between 102 and 107 degrees each day between September 4 and September 9.

A large upper ridge pushed into California from the eastern Pacific Ocean on September 3 and shifted inland and strengthened on September 5 and 6. This resulted in a period of much of above normal temperatures over the area with Heat Risk reaching high levels across the San Joaquin Valley, West Side Hills and Kern County Deserts. The ridge finally broke down and shifted east of the region on September 10 as a trough pushed into the Pacific Northwest.
