Riverside and San Bernardino are baking under sunny skies today, Wednesday, July 15, with the high expected near 102°F as the Inland Empire’s heat officially peaks, according to the National Weather Service. If you’ve got errands or outdoor plans, front-load them into the early morning or push them past sunset.

Today’s Setup

Forecasters at the NWS San Diego office say today’s heat is running 5 to 10 degrees above average for the Inland Empire, with highs reaching the upper 90s to near 102°F away from the coast. Southwest winds stay manageable, around 0 to 15 mph with gusts as high as 25 mph, so expect a little blowing dust around exposed spots like the Santa Ana River bike path or Box Springs Mountain trails. Overnight lows only drop to around 69°F, so the air stays warm well after dark.

Best Window To Be Outside

Mornings before 9 AM and evenings after 7 PM are your best bet for anything active — a walk at Fairmount Park, a round of golf, or a stroll through downtown Riverside. It’s good golf weather early, but plan to be off the course before the midday sun takes over. Skip strenuous outdoor work between noon and 5 PM.

Heat And Rain Risk

There’s essentially no rain in the picture today (just a 3% chance), so hydration is the main concern. A Yeti rambler water bottle is worth keeping full and nearby, and if the kids need to cool off, this is a great afternoon for water guns super soaker in the backyard. For a lazier way to beat the heat at a local pool or lake, the 2-Person Intex Floating Lounge with Cooler Just $24 on Amazon is a smart grab before the weekend.

What’s Changing This Week

The NWS expects Thursday’s high to ease a few degrees to around 100°F, with monsoonal moisture returning and a slight chance of afternoon showers — mainly over the mountains. Friday brings real relief, with highs cooling closer to seasonal averages. If you want an early escape from the valley heat, Big Bear or Joshua Tree make for a solid weekend reset, and now’s a good time to lock in a VRBO weekend cabin rental before everyone else has the same idea.

Game Day And Concerts On The Horizon

The Los Angeles Angels host the Detroit Tigers at Angel Stadium on July 18, with manageable evening temperatures expected for tailgating. Grab a Los Angeles Angels jersey or Los Angeles Angels fitted cap before you go — Get tickets on SeatGeek or Find tickets on StubHub while seats remain. Down in San Diego, Evanescence plays North Island Credit Union Amphitheatre on July 17 (Evanescence t-shirt), and Ed Sheeran’s LOOP Tour hits Petco Park on July 21 — an Ed Sheeran t-shirt or Ed Sheeran hoodie makes a fun keepsake if you’re making the drive.

Tonight’s Dinner Idea

This is textbook grilling weather — fire up the grill for burgers, steaks, or grilled chicken with corn on the cob while it’s warm enough to eat outside after sunset. An instant-read meat thermometer takes the guesswork out of doneness, and a grill brush and scraper set keeps the grates ready. Want to switch it up?

Next Few Days

Expect a gradual cool-down: today’s peak near 102°F eases to around 100°F Thursday, then falls closer to seasonal averages by Friday and holds through the weekend, aside from a slight mountain shower chance each afternoon.

Upcoming Home Games
