San Diego to Remain in Grip of Heat Wave Through Weekend, Forecasters Say

Forecasters said inland valleys could reach 104 to 107 degrees, and heat advisories or extreme heat warnings are possible.

  • The National Weather Service warned that a significant heat wave will push temperatures above 100 degrees across Southern California beginning Thursday, with triple-digit temperatures becoming common away from the coast and the warmest communities reaching between 104 and 107 degrees.
  • A warming trend beginning Monday accelerated through the week, with valley temperatures remaining in the 90s through Wednesday before climbing into triple digits Thursday as onshore trends weakened, creating what forecasters described as a potentially long and dangerous heat wave.
  • Meteorologist Ryan Kittell, with the National Weather Service's Oxnard office, called this "the hottest stretch so far this year," while colleague Robbie Munroe warned the heat wave's duration "can really be concerning," with temperatures potentially reaching 109 in Paso Robles and exceeding 110 in desert areas.
  • Heat advisories span from 10 a.m. Wednesday through 8 p.m. Monday, with the Antelope Valley upgraded to an extreme heat warning expecting highs of 100 to 108 degrees, while Los Angeles maintains more than 100 public cooling locations accessible via 311.
  • Above-Normal temperatures could extend into late July and beyond, with a 60% to 80% chance between July 27 and August 2 according to meteorologist Robbie Munroe, as warm overnight lows provide little relief and humid conditions intensify discomfort across inland regions.
