Riverside–San Bernardino wakes up to patchy fog Wednesday morning, but skies clear by around 11 AM PT for a mostly sunny afternoon with a high near 79°F — a great day to get outside once that marine layer burns off. West winds reach 0–15 mph with gusts up to 25 mph, so grab a light layer for your morning commute through Jurupa Valley or along the Santa Ana River Trail before shedding it by lunch.
Today’s Setup
The National Weather Service notes the marine layer deepened to around 3,000 feet overnight, pushing low clouds well into the valleys. Expect reduced visibility through the Inland Empire corridor through mid-morning — allow extra time if you’re heading out early. Once that fog lifts around 11 AM PT, plan on a classic spring afternoon: sunshine, mild temps, and a refreshing sea breeze keeping things comfortable.
Best Window To Be Outside
Your outdoor sweet spot runs from late morning through early evening. Box Springs Mountain Reserve and the trails around Lake Perris will look inviting this afternoon. Golfers, conditions post-fog are solid — if you’re stocking up for the season, check our best golf balls for high handicappers in 2026 guide for some tested picks. Wind gusts up to 25 mph may affect club selection on exposed holes, so plan accordingly.
Allergy Watch
Inland Empire spring pollen is no joke. The onshore breeze can push coastal allergens well inland, and the marine layer burn-off tends to stir up particulates through the valley. If you’re sensitive, running a HEPA air purifier at home and swapping in a washable HVAC air filter MERV 13 before summer A/C season cranks up can make a real difference. Check the Riverside–San Bernardino weather forecast for air quality updates as warming continues.
Dodgers vs. Giants Tailgate Forecast
Baseball fans are in luck this week. The Los Angeles Dodgers host the San Francisco Giants at Dodger Stadium on Thursday, May 14, under near-perfect conditions: morning fog clears early, sunny skies take over, and the high climbs to near 82°F with a light west breeze. Tailgating in the Dodger Stadium lots should be comfortable — bring sunscreen and maybe a Los Angeles Dodgers fitted cap or a Los Angeles Dodgers jersey to represent. You can Get tickets on SeatGeek or Find tickets on StubHub if you still need seats for the series.
Also on Friday, May 15, the P!NK concert at Petco Park is worth the drive toward San Diego — mild, dry evening conditions make it ideal for an outdoor show. A P!NK hoodie is smart for the cooler coastal air after sundown.
Tonight’s Dinner
A pleasant 56°F evening calls for something simple and satisfying — pasta or a quick stir-fry hits the spot. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Thursday brings sunny skies and a high near 82°F — a notch warmer than today, with morning fog again clearing by 11 AM PT. The National Weather Service forecasts continued warming into Friday, with Inland Empire highs potentially ranging from the upper 70s to upper 80s. Enjoy it while it lasts: stronger onshore flow returns for the weekend, bringing noticeable cooling by Sunday. Then early next week warms back up — Tuesday’s inland highs are expected to run 5–10 degrees above average.
