Riverside and San Bernardino start Tuesday under full sun and a high near 96°F, with a Heat Advisory in effect through Saturday — get outdoor chores, dog walks, or golf in before midday and lean on shade and water once the afternoon sun takes over.
Today’s Setup
Expect zero chance of rain, a high near 96°F, and a west wind of 0 to 15 mph with gusts as high as 25 mph that stirs the air but won’t cool much. Overnight lows dip to a comfortable 69°F, and Wednesday repeats the pattern almost exactly — sunny, high near 95°F, southwest wind 0 to 10 mph with gusts to 20 mph. Forecasters at the National Weather Service note inland high temperatures will run 5 to locally 10 degrees above average through Thursday, keeping the Inland Empire in the 90s to around 103 while the low deserts push 110 to 115.
Best Window To Be Outside
Mornings before 10 AM PT are the best bet for yard work, dog walks, or an early tee time — calm air and full sun make for ideal golf conditions before that west wind gusts near 25 mph by afternoon. Push errands or shaded activities to after 6 PM PT once temps ease back toward the overnight low.
Heat Risk & Safety
The NWS has a Heat Advisory posted for the Inland Empire and surrounding mountains through Saturday, with HeatRisk running moderate here — and major to locally moderate in the deserts, where an Extreme Heat Warning stays in effect through Saturday too. If you’re headed toward Joshua Tree this week, that desert heat risk is serious; Big Bear is the smarter pick if you want cooler mountain air instead. Keep an insulated water jug 1 gallon in the car, and men’s sport sandals plus a hat make midday errands more bearable.
Local Games & Events
Making the drive to San Diego? Los Angeles Chargers Training Camp is underway at USD Torero Stadium on Wednesday, August 5 — bring water for the hot, sunny drive and grab official team gear on Fanatics before you head out. Closer to home, Lionel Richie and Earth, Wind & Fire play Acrisure Arena at Greater Palm Springs on Saturday, August 8 — with the desert’s Extreme Heat Warning still active that day, plan for triple-digit heat getting into the venue. Find tickets on StubHub and grab a Lionel Richie t-shirt for the show.
Dinner Tonight
Clear skies and light evening wind make tonight perfect grilling weather — fire up the grill for burgers, steaks, or grilled chicken with corn on the cob. An instant-read meat thermometer and a grill brush and scraper set make the cookout easier from start to cleanup, and our guide on how to smoke tri-tip like brisket is worth a look if you want to switch things up. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Expect the sunny, hot pattern to hold Wednesday through Saturday as high pressure strengthens, with HeatRisk ticking back up late week for the Inland Empire, mountains, and deserts alike. Forecasters are watching a possible influx of monsoonal moisture for next Sunday and Monday that could bring a slight chance of afternoon showers and thunderstorms to the mountains — worth watching if you’ve got weekend plans up that way.
