San Diego, CA — Residents across the San Diego region should brace for extreme heat on Friday, as temperatures are forecasted to soar well above seasonal averages. Inland valleys will experience highs from the mid-80s to mid-90s, while areas in the lower deserts, such as Palm Springs and Thermal, could see temperatures climbing as high as 113°F. The intense heat is expected to persist throughout the weekend.
According to the National Weather Service, this spike in temperatures will primarily affect desert and valley regions, making it vital for those living in these areas to stay hydrated and limit outdoor activities during peak heat hours. Residents traveling along I-15 through San Bernardino and Riverside counties should also be cautious of potential heat-related vehicle issues.
For the coastal areas, highs will stay more moderate, hovering around 70°F, providing a cooler escape from the intense inland temperatures. Apple and Lucerne Valleys will also see highs in the 90s. Mountain regions, at elevations of 4500 to 7000 feet, will offer some relief, with temperatures ranging from the mid-70s to upper 80s.
