Riverside–San Bernardino wakes up Monday under patchy fog that clears by 8 AM, giving way to full sunshine and a high near 90°F — grab your insulated tumbler 30oz and plan your outdoor time early before this week’s heat really cranks up.
Today’s Setup
The morning fog will burn off fast across the Inland Empire, leaving sunny skies and a west breeze of 0 to 10 mph with gusts up to 20 mph. That airflow keeps things manageable through mid-morning, but by afternoon the heat is in charge. Good news: tonight drops to a comfortable 62°F under mostly clear skies — great sleeping weather while it lasts.
Heat Risk Builds Tuesday and Wednesday
The National Weather Service is flagging moderate HeatRisk for portions of the Inland Empire on Tuesday and Wednesday as strengthening high pressure builds to the east. Both days push near 95°F — 5 to 10 degrees above average for inland areas. If you work outdoors near the Moreno Valley distribution hubs, the Perris Valley, or anywhere with limited shade, plan for extra breaks and shade by midday. Relief is on the horizon: a gradual cooling trend begins Thursday, and by next Sunday highs could run 8 to 12 degrees below average for the valleys.
Best Window To Be Outside
Get your walk, ride, or yard work done before 10 AM. The Santa Ana River Trail and Box Springs Mountain Regional Park are excellent early-morning options. After 6 PM, temps drop quickly and those westerly breezes return — evening picnics and patio dinners are back in play. If the community pool is calling, check out the 2-Person Intex Floating Lounge with Cooler — it’s a summer essential when triple-digit heat is lurking.
Angels at Angel Stadium — Tuesday and Wednesday
The Los Angeles Angels host the Baltimore Orioles on Tuesday, June 23 and Wednesday, June 24 at Angel Stadium in Anaheim. First-pitch temperatures could still be running near 90°F, so come prepared. An insulated tumbler 30oz keeps drinks cold through nine innings. Quick dry swim trunks and men’s sport sandals are smart choices for the bleachers, and a Los Angeles Angels fitted cap will shield you from the afternoon sun. A breathable Los Angeles Angels jersey rounds out the gameday look. Find tickets on StubHub or Get tickets on SeatGeek before seats go fast.
What To Wear
Light, breathable fabrics are the only answer this week. A women’s swimsuit doubles as a pool-day outfit, and a beach towel oversized is worth keeping in the trunk — splash pads and community pools across the IE will be packed. Pack sunscreen regardless of where you’re headed.
Cool-Down Meal Idea
Skip the oven entirely tonight. Smoothie bowls or a cold Thai noodle salad are exactly right when it’s 90°F. A high-powered blender makes quick work of smoothie bowls and frozen fruit drinks. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Tuesday and Wednesday stay near 95°F with moderate HeatRisk in effect for the Inland Empire — the National Weather Service notes some mid- and high-level clouds may drift in from the southeast late Tuesday into Wednesday, but no rain is expected. A slow cooldown arrives Thursday and continues through the weekend. Browse outdoor gear deals now so you’re ready when temperatures finally cooperate for that Big Bear or Joshua Tree weekend trip.
