Orange County Faces Scorching Heat Spike with Excessive Heat Watch Issued
Orange County is bracing for a significant heat spike, particularly in inland areas, with an Excessive Heat Watch issued by the National Weather Service (NWS). This alert will be in effect from Tuesday until 8 p.m. Wednesday, during which residents can expect temperatures to soar into the low-90s in Mission Viejo.
High temperatures are anticipated to impact several communities, with Mission Viejo projected to reach maximums in the low-90s. Inland cities such as Anaheim, Santa Ana, Irvine, Garden Grove, Orange, Fullerton, and Mission Viejo will be under a heat advisory until the same time. Coastal areas are expected to see milder temperatures, ranging from 79 to 83 degrees on Wednesday, providing some relief to those near the shoreline.
Weather Forecast and Advisory
From Tuesday to Wednesday, the temperature in Mission Viejo is expected to rise, with light winds up to 10 miles per hour making it feel even warmer. Other areas forecasted to feel the heat include Palm Springs with a staggering 118 degrees, Palmdale at 103 degrees, and 101 degrees expected in San Bernardino. Additional temperatures on Wednesday will include:
- 100 degrees in Santa Clarita, Woodland Hills, Ontario, Lake Elsinore, and Paso Robles

Health and Safety Precautions
The NWS has cautioned that the extreme heat could lead to heat-related illnesses. Residents are strongly advised to stay hydrated by drinking plenty of fluids, remain indoors in air-conditioned spaces, and seek shade if they must be outdoors. Furthermore, individuals are reminded not to leave pets or children in vehicles, as conditions can quickly turn life-threatening.
Increased Fire Risks Across California
Alongside the heat, increased fire conditions are anticipated across California due to high temperatures, gusty winds, and low humidity. This raises the risk for grass fires, particularly in specific areas such as the Grapevine section of Interstate 5, Ventura County mountains, Antelope Valley, Santa Ynez mountains, and the interior valleys of San Luis Obispo County. An extreme heat warning has also been issued for Death Valley National Park and surrounding regions from 10 a.m. Wednesday through 10 p.m. Thursday.
Additionally, the weather service in Reno has issued a fire weather watch for Alpine and Mono counties and parts of western Nevada, including Reno and Carson City, from Thursday afternoon to Friday afternoon. Residents of these areas should remain vigilant and prepared for potential fire hazards.
Recent Heat Events and Expected Cooldown
The preceding Tuesday saw Southern California experiencing temperatures as high as 102 degrees in Woodland Hills and 89 degrees in downtown Los Angeles. Coastal regions reported more temperate conditions, with highs of just 78 degrees at Los Angeles International Airport and around 77 degrees in both San Diego and Redondo Beach.
A cooldown is anticipated to begin on Thursday, coinciding with the observance of Juneteenth, providing residents with some respite from the extreme heat.
