Extreme Heat Watch Issued for Los Angeles County

July 12, 2026 · wweather1 editorial · 2 min read

The National Weather Service Los Angeles/Oxnard, CA, has issued an Extreme Heat Watch for several areas within Los Angeles County, effective until July 16 at 8:00 PM PDT. Dangerously hot conditions, with temperatures potentially reaching 108 degrees Fahrenheit, are possible.

The National Weather Service (NWS) Los Angeles/Oxnard, CA, has issued an Extreme Heat Watch for various areas across Los Angeles County. Affected regions include the Eastern and Western San Fernando Valley, Santa Clarita Valley, Santa Susana Mountains, Los Angeles County San Gabriel Valley, and the Los Angeles County Inland Coast, including Downtown Los Angeles.

A Heat Advisory will be in effect from 10 AM PDT Sunday to 10 AM PDT Tuesday, with expected temperatures ranging from 85 to 98 degrees Fahrenheit. This is followed by the Extreme Heat Watch, which anticipates dangerously hot conditions with temperatures of 90 to 108 degrees Fahrenheit possible, starting Tuesday morning and continuing through Thursday evening. The Extreme Heat Watch itself is issued until July 16 at 8:00 PM PDT, with the warmest temperatures expected in the valleys.

These high temperatures pose a high risk for dangerous heat illness for anyone, particularly the very young, the very old, those without air conditioning, and individuals active outdoors. Monsoonal moisture is also expected to contribute to discomfort levels from Sunday and throughout the week.
