Riverside–San Bernardino is in for another blazing Thursday, with highs climbing to near 92°F this afternoon — running 5 to 10 degrees above seasonal averages and enough to keep much of the Inland Empire under a moderate HeatRisk for the day.
Today’s Setup
The National Weather Service forecasts sunny skies with a southwest breeze of 0 to 15 mph and gusts up to 25 mph by afternoon. You may notice marine low clouds lingering near the western valleys at sunrise — that’s normal for early June — but they’ll burn off quickly. By late morning, the valley floor from Fontana to Redlands will be baking under full sun. Tonight brings mostly clear skies with a comfortable low around 63°F.
Best Window To Be Outside
If you’re planning outdoor activity, aim to be done by 10 AM. The Santa Ana River Trail, Box Springs Mountain Reserve near Moreno Valley, and the trails around Lake Perris are all reasonable early-morning options. By 2–3 PM, the pavement radiates stored heat and most IE trailheads become punishing. Bring more water than you think you’ll need — dehydration sneaks up fast above 90°F.
Heat and Fire Danger
Hot temps, low humidity, and gusty afternoon winds are a dangerous combination in this wildfire corridor. Foothill and interface communities near Redlands, Loma Linda, Highland, and the Cajon Pass should stay alert. At minimum, confirm you have a working fire extinguisher home and a smoke detector combo pack with fresh batteries. Stage a go bag emergency evacuation kit near your door so you’re not scrambling if conditions change fast. If smoke drifts into the valley from any direction, an N95 respirator mask smoke will protect your lungs. This isn’t alarmism — it’s just living smart in the IE.
Weekend Games & Events
Angels fans have two home games to look forward to: the Los Angeles Angels host the Tampa Bay Rays at Angel Stadium in Anaheim on both Saturday, June 13, and Sunday, June 14. Expect temps near 90°F at first pitch Saturday — wear light clothing, hydrate early, and bring sunscreen. Grab a Los Angeles Angels jersey to represent, and Get tickets on SeatGeek before seats thin out.
Desert-dwellers and day-trippers, mark June 17 on the calendar: Shakira’s Las Mujeres Ya No Lloran World Tour hits Acrisure Arena at Greater Palm Springs. It’s an indoor, air-conditioned venue, so the desert heat stays outside. Pick up a Shakira t-shirt or Shakira hat and Find tickets on StubHub.
What To Eat Tonight
Nobody should be turning on the oven at 92°F. Cold Thai noodle salad, smoothie bowls loaded with frozen fruit, or a build-your-own wrap bar are the moves. A high-powered blender makes smoothie bowls effortless. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Friday delivers more of the same — sunny with a high near 92°F, and the National Weather Service specifically flags Friday as the peak day for moderate HeatRisk coverage across the Inland Empire. There’s also a slight chance of afternoon showers near the San Bernardino Mountains, so Big Bear hikers and campers should watch the sky. Saturday eases just slightly to near 90°F under continued sunshine. No relief is in sight through the weekend. Follow the Riverside–San Bernardino weather forecast for updates and check outdoor gear deals if you’re stocking up for a hot summer ahead.
