Southern California Braces for Record-Breaking Heat Friday as Temperatures Soar into 90s and Near 100 in Desert Areas

CALIFORNIA — Forecasters say Friday will be the warmest day of the week across Southern California, with widespread 80s and 90s expected outside the higher mountain elevations — and some desert communities nearing the 100-degree mark.

The heat surge is projected to run 15 to 25 degrees above average, raising the potential for several daily temperature records to be broken.

Widespread 90s Across Inland Communities

Forecast high temperatures show much of inland Southern California heating up significantly:

Anaheim & Riverside: around 93°F
San Bernardino: near 93°F
Ontario: near 92°F
Lake Elsinore & Temecula: around 92°F
El Cajon: near 93°F
Palm Springs: around 97°F
Thermal: near 99°F
Borrego Springs: near 97°F
Ocotillo Wells: near 98°F

Coastal areas will be slightly cooler but still warm for this time of year, with places like Irvine near 90°F and Oceanside around 80°F.

Higher elevations, including Big Bear Lake and mountain communities, will remain cooler but still above seasonal norms.

Record Highs Possible

Meteorologists indicate that Friday’s temperatures could challenge or break daily records in several locations. With highs running 15–25 degrees above average, the warmth stands out as an early-season spike.

Desert areas are expected to experience the most extreme readings, approaching triple digits.
