What’s causing the heat? Belen De Leon has the forecast for March 19, 2026.

Friday’s weather

The region’s 4-day-long Extreme Heat Warning is set to expire at 8 p.m. Friday.

NBC Los Angeles meteorologist Belen De Leon said temps will remain hot throughout the day. Here’s a glimpse of what to expect:

87 degrees in Long Beach

93 degrees in Los Angeles

93 degrees in Anaheim

97 degrees in Van Nuys

99 degrees in West Covina

100 degrees in Riverside

100 degrees in San Bernardino

What’s next?

According to De Leon, the high-pressure system causing this week’s heat wave will shift somewhat east this weekend. That will bring slightly cooler temperatures to the region, but not by much. The high-pressure system will linger through next week.

“Our temperatures are still going to feel like summer, at least through the end of next week,” she said.

De Leon said next week will be warm, but the heat won’t be extreme as what we experienced this week.

Why is it so hot in March in Southern California?

Earlier this week, De Leon explained why it’s so hot in March in SoCal. She said a high-pressure system paired with a few other factors is making it feel more like summer.
