Riverside–San Bernardino is in for a beautiful Friday with a high near 85°F and wall-to-wall sunshine — great news for anyone with outdoor plans across the Inland Empire today. The National Weather Service calls for west winds 0 to 15 mph with afternoon gusts up to 25 mph. Some patchy fog may linger in western valley areas through mid-morning before clearing; once it does, you’ve got nearly ideal conditions for hiking, golfing, or knocking out yard work before the weekend.
Today’s Setup
A weak upper-level low pressure system to the southwest is nudging temperatures 3–5 degrees above normal — that’s where Friday’s 85°F high originates. Skies stay sunny through the afternoon, with overnight lows easing to around 57°F under partly cloudy skies. The National Weather Service notes the marine layer filled in more aggressively than recent nights, so don’t be surprised by patchy fog after 5 AM — thickest in the western Inland Empire and valley floors near Jurupa Valley and Fontana.
Best Window To Be Outside
Mid-morning through early afternoon is your golden window. Fog typically lifts by 10–11 AM, handing off to clear skies before afternoon winds ramp up. Box Springs Mountain Reserve, Fairmount Park in Riverside, and the trails above Redlands are in great shape today. If you’ve been waiting to apply lawn fertilizer spring treatments, this kind of dry, calm morning is perfect before the breeze picks up. For sun protection, the UPF 50+ Fishing Shirts for $6.50 deal is hard to pass on before your next outing.
Allergy Watch
Clear, breezy late-May days push pollen counts higher across the Inland Empire — a classic pattern for this region. Before stepping outside, grab Zyrtec 24 hour allergy 90 count, and keep an allergy relief nasal spray handy if symptoms flare during those gusty afternoon hours. Closing windows when you return indoors and staying hydrated will also help.
Angels at Angel Stadium This Weekend
Saturday’s forecast is nearly a copy of Friday — a high near 84°F after morning fog clears by around 11 AM. That sets up beautifully for the Los Angeles Angels vs. Texas Rangers at Angel Stadium on Saturday, May 23. Afternoon conditions look sunny with a light breeze — tailgating doesn’t get much better in late May in Anaheim. Rep the Halos with a Los Angeles Angels jersey or Los Angeles Angels fitted cap. Still hunting for seats? Find tickets on StubHub or Get tickets on SeatGeek while options are available.
Next Few Days
Minor cooling arrives Sunday, with a more notable dip by Memorial Day — the National Weather Service says valley highs could run 3–7 degrees below normal by then, a welcome break for Big Bear Lake and Joshua Tree weekend trips. The marine layer deepens through next week with morning fog lifting by mid-morning each day. A stronger system may push through midweek; worth watching if you have outdoor plans for the holiday stretch.
For tonight, keep dinner relaxed — a pasta primavera or quick veggie stir-fry suits these mild spring evenings perfectly. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered right to your door.
