Quick Facts
    • Today’s weather: Hot, hazy
    • Beaches: 90s
    • Mountains: 90s-100s
    • Inland: 100-110
    • Deserts: 100-110
    • Warnings and advisories: Wildfire smoke, excessive heat, red flag

It's been 100 degrees or more these past few days but the good news is that we're in the last stretch of the heatwave. The excessive heat warnings for most the Southern California and red flag warnings for Santa Barbara County ends tonight.

Forecasters say that come tomorrow (Tuesday, Sept. 10) the Southland will begin to cool down between five and 10 degrees. Later this week expect much cooler temperatures — 80s for the valleys and 70s along the coast.

Highs at the beaches will be in the 90s and we're looking at highs in the 100s still for the valleys and inland areas.

Some notable forecasts:

  • Downtown L.A. will reach up to 101 degrees.
  • Woodland Hills will reach up to 110 degrees.
  • Highland, were the Line Fire is actively burning, will see a high of 107 degrees.
  • Coachella Valley will reach up to 111 degrees.

There's a small chance of thunderstorms over the San Bernardino Mountains later this afternoon.

A wildfire smoke advisory has been extended until tonight as wildfires continue to burn across the Southland. That means this afternoon the skies will be hazy and sunny. The smoke will heavily impact L.A, Orange, San Bernardino and Riverside counties.

Here's how you can protect yourself from wildfire smoke.

Where to cool down

In L.A., Orange, San Bernardino, and Riverside counties, call 3-1-1 or call for a list of cooling centers. In the city of Los Angeles, you can also find a list of recreation centerssenior centers and libraries — all good choices for cooling off — online.

  • Tip: Call the center in advance to make sure seating is available.
  • Tip: If the center you want is at capacity, or non-operational, head to a local, air-conditioned library and cool off with a book about ice fishing in Antarctica.

As Editor-in-Chief of our newsroom, I’m extremely proud of the work our top-notch journalists are doing here at LAist. We’re doing more hard-hitting watchdog journalism than ever before — powerful reporting on the economy, elections, climate and the homelessness crisis that is making a difference in your lives. At the same time, it’s never been more difficult to maintain a paywall-free, independent news source that informs, inspires, and engages everyone.

Simply put, we cannot do this essential work without your help. Federal funding for public media has been clawed back by Congress and that means LAist has lost $3.4 million in federal funding over the next two years. So we’re asking for your help. LAist has been there for you and we’re asking you to be here for us.

We rely on donations from readers like you to stay independent, which keeps our nonprofit newsroom strong and accountable to you.
