LOS ANGELES, Calif. — Southern California is heading into an increasingly intense stretch of summer heat as a strengthening ridge of high pressure pushes temperatures well above normal across the region.
Forecasters expect triple-digit temperatures in several inland communities, with little indication of a meaningful cooldown over the coming days.
Saturday is already expected to bring significant heat, with temperatures reaching around 97 degrees in the Los Angeles area and approximately 104 degrees in the Inland Empire.
“The heat is on in a very big way,” forecasters said.
The forecast is expected to become even more challenging early next week as high pressure strengthens over the region.
Inland Areas Face the Worst of the Heat
The Santa Clarita Valley is among the areas facing especially high temperatures.
A heat advisory remains in effect there, with temperatures expected to reach about 101 degrees Saturday. Forecast highs are then expected to climb to 103 degrees Tuesday and 104 degrees Wednesday.
The Inland Empire is forecast to experience even more extreme conditions. Temperatures could reach 104 degrees Saturday, before rising to around 105 degrees Tuesday and 106 degrees Wednesday.
Those temperatures are far above what many residents would consider comfortable, and the prolonged nature of the heat is raising concerns for people who may not have easy access to cooling.
Ventura County will remain somewhat cooler but is also expected to warm considerably. After reaching around 90 degrees Saturday, temperatures could rise to approximately 95 degrees Tuesday.
Forecasters Warn There Is Little Relief Ahead
Unfortunately for residents hoping the weekend heat will quickly fade, forecasters say the opposite may happen. Forecasters said there is “no relief in sight” as the ridge of high pressure strengthens over Southern California.
The weather pattern is expected to keep temperatures elevated throughout much of the coming week. Some locations may start the day with partly to mostly cloudy skies, but sunshine is expected to take over during the afternoon.
That combination could allow temperatures to climb rapidly after the morning clouds clear.
The coast will continue to offer some relief compared with inland communities. Low clouds and fog are expected to remain largely confined to coastal areas, with the marine layer Saturday morning not expected to push very far into the Los Angeles Basin.
Monsoonal Moisture Could Bring Storm Chances
The heat will not be the only weather factor residents need to watch.
Some monsoonal moisture is expected to move into the atmosphere in the coming days, increasing the potential for showers and thunderstorms.
While the coast and inland valleys may experience very different conditions, the added moisture could contribute to changing weather patterns across parts of Southern California.

Residents should continue monitoring local forecasts as conditions evolve, particularly if thunderstorms develop in areas that have been experiencing prolonged hot weather.
Heat and Air Quality Add to Health Concerns
The prolonged stretch of extreme temperatures could create serious health risks, particularly for children, older adults, pets and people who spend extended periods outdoors.
Residents are being urged to stay hydrated, avoid strenuous activity during the hottest part of the day and never leave children or pets unattended inside vehicles.
The combination of heat and poor air quality is another concern.
They said unhealthy air conditions were reported around Redlands, while areas including Rancho Cucamonga were experiencing air quality considered unhealthy for sensitive groups Saturday morning.
People with respiratory conditions may be particularly vulnerable and should take precautions when spending time outdoors.
With temperatures expected to climb further next week, Southern California residents are being urged to prepare for several more days of intense heat rather than expecting a quick break.
