Riverside-San Bernardino weather today is sunny and warming to 85°F, making it an ideal Saturday for getting outside across the Inland Empire.
Clear skies will dominate through the overnight hours, with lows dropping to around 52°F by early morning—perfect sleeping weather if you crack a window. Once the sun comes up Saturday morning, expect mostly sunny conditions with northwest winds staying light to moderate (0–15 mph, with gusts up to 25 mph). This is classic spring weather for our region, and it’s your green light to tackle outdoor projects, hit the trails, or plan a day trip to Joshua Tree or Big Bear.
What to Do This Weekend
If you’re thinking about heading to Joshua Tree National Park or exploring the high desert around Victorville, Saturday is your day. Temperatures in the low desert will climb into the upper 80s, while mountain areas stay comfortably in the upper 50s to upper 60s—excellent for hiking without the extreme heat. The light winds mean minimal dust stirring up, which is a bonus for air quality.
Sunday follows suit with mostly sunny skies and another high near 85°F. Onshore flow begins returning Sunday night, which will bring cooler air inland by Monday, so don’t wait if you’re planning weekend adventures.
Allergy Alert
With spring in full bloom and light winds keeping pollen concentrated, Saturday is a higher-pollen day across the region. If you’re sensitive to tree and grass pollen, consider keeping an allergy relief nasal spray handy, especially during peak outdoor hours. A pollen count face mask can help if you’re doing yard work or hiking. Indoor folks might benefit from a HEPA air purifier to keep your home’s air clean while enjoying the breeze outside.
Tailgating & Sports Weather
If you’re heading to Crypto.com Arena in Los Angeles for the Lakers vs. Rockets playoff game tonight (Saturday, April 18), you’ll have perfect conditions for pre-game tailgating—mild temperatures, clear skies, and light winds. Bring a light jacket for after the game when it cools to the mid-50s.
Looking Ahead
Monday brings the first shift: onshore flow strengthens, and cooling begins spreading inland. By midweek, expect gusty winds through the passes and canyons, with highs dropping 3–8 degrees below normal. There’s also a slight chance of light precipitation Tuesday into Wednesday morning—nothing severe, but keep an eye on conditions if you’re planning outdoor activities.
Tonight’s Dinner
With pleasant evening temperatures and clear skies, Saturday is perfect for grilling. Fire up some burgers, steaks, or veggie kabobs—the mild winds won’t cause flare-ups, and you’ll have comfortable outdoor dining weather until sunset around 7:30 PM. Pair it with fresh salads and cold drinks. Did you know you can order groceries on Amazon Fresh for all your grilling essentials? Get everything you need delivered straight to your door.
Next 7 Days: Sunday stays mostly sunny and warm (85°F). Monday begins cooling with increasing onshore flow. Mid-week sees gusty winds and slight rain chance. Conditions gradually settle by Friday.
