Topline:

It's been pretty cool so far this year, but brace yourself: Summer temperatures are finally here, with up to 95-105 degrees in some parts of Southern California.

When will it be hottest?: Hot temperatures are expected until Tuesday, but the National Weather Service expects Saturday will see the hottest temperatures.

What are the maximum temperatures?: Interior areas could cross 100 degrees this weekend, including a forecasted high of 106 in Lancaster. Meanwhile, the mountains and foothills are looking at a forecast of between 85 and 95 degrees. The coasts will likely see highs of between 70 and 75 degrees.

Any other weather events?: The heat is the main thing to look out for, but there could be wind gusts of up to 40 miles per hour overnight. There's also a small chance of thunderstorms and potential lightning strikes this weekend, especially in the afternoon hours. Large grass fires are also possible.

The backstory: Summer also means the start of wildfire season, and following a wet winter, the risk of wildfires (and poor air quality) is up too. Firefighters are warning of the potential of a bigger fire year after a few quiet fire seasons in Southern California.

How to protect yourself: With higher temperatures comes higher chance of heat exhaustion and heat stroke, especially in vulnerable populations. Drink lots of water if you're going to be outside or in a hot place — and not just if you're thirsty. And watch out for dizziness, fatigue, and other signs of heat illness.

How to stay cool: For people without air conditioning (or without a way to get to the coast), we have some advice to help you to stay cool without AC.

Where is the closest cooling center: 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 centers, senior 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.

At LAist, we believe in journalism without censorship and the right of a free press to speak truth to those in power. Our hard-hitting watchdog reporting on local government, climate, and the ongoing housing and homelessness crisis is trustworthy, independent and freely accessible to everyone thanks to the support of readers like you.

But the game has changed: Congress voted to eliminate funding for public media across the country. Here at LAist that means a loss of $1.7 million in our budget every year. We want to assure you that despite growing threats to free press and free speech, LAist will remain a voice you know and trust. Speaking frankly, the amount of reader support we receive will help determine how strong of a newsroom we are going forward to cover the important news in our community.

We’re asking you to stand up for independent reporting that will not be silenced. With more individuals like you supporting this public service, we can continue to provide essential coverage for Southern Californians that you can’t find anywhere else. Become a monthly member today to help sustain this mission.

Thank you for your generous support and belief in the value of independent news.
