Riverside–San Bernardino is waking up to a warm, sunny Tuesday with highs climbing near 86°F — a great day to get outside, with one caveat: watch those gusty north winds picking up by afternoon.
Today’s Setup
Weak offshore flow is holding over the Inland Empire, pushing temperatures about 5 degrees above average and keeping skies completely clear. The National Weather Service is forecasting north winds of 0–15 mph with gusts as high as 25 mph developing through the afternoon. Tonight looks comfortable — clear skies and a low around 57°F with south winds shifting back in. Leave a window cracked once that evening breeze kicks in.
Best Window To Be Outside
Get out early. Morning hours along the Santa Ana River Trail, Fairmount Park, or any of the area’s golf courses will be calm and gorgeous. By mid-afternoon, those 25 mph gusts make outdoor dining and anything in open spaces noticeably less pleasant. Cyclists and hikers near the Box Springs Mountain Reserve should aim for a morning start.
Allergy Alert
Dry, breezy, warm days like today drive pollen counts up across the valley floor — and this week’s persistent offshore flow means little marine moisture to wash it out. If your nose has been running, this is peak misery season. Running a HEPA air purifier indoors and stashing an allergy relief nasal spray in your bag can make a meaningful difference, especially after time spent outdoors near open fields or the foothills.
Angels Series at Angel Stadium
Planning a trip to Anaheim this week? The Los Angeles Angels host the Athletics on May 20, 21, and 22 at Angel Stadium — and all three games look like weather winners. Wednesday’s forecast mirrors today almost exactly: sunny with a high near 87°F and southwest winds gusting to 30 mph. A Los Angeles Angels fitted cap is essential for those sun-exposed bleacher seats, and showing up in a Los Angeles Angels jersey is half the fun. Find tickets on StubHub before the series sells out.
What To Bring
Pack a Stanley quencher tumbler with ice water for any outdoor stretch — upper-80s temperatures with afternoon wind drain you faster than you’d expect. Sunscreen and sunglasses are non-negotiable. If you’re planning a weekend run out to Joshua Tree or Big Bear, note that the National Weather Service expects patchy fog to develop in the valleys by Wednesday night and morning marine layer to push farther inland through the weekend, so conditions will shift.
Dinner Tonight
A warm evening in the mid-70s calls for something light — pasta or a quick stir-fry won’t heat up the house and comes together fast after a long day outside. Need ingredients? You can order groceries on Amazon and have everything for tonight’s dinner delivered to your door.
Next Few Days
Wednesday tops near 87°F with southwest winds gusting up to 30 mph — nearly a carbon copy of today. Wednesday night, patchy fog is expected to develop, and the National Weather Service notes the marine layer will begin pushing into the inland valleys by the weekend, bringing a gradual cool-down to the Riverside and San Bernardino areas. No rain is in the forecast through at least mid-week. Temperatures should ease a few degrees by next weekend.
Stay current with the Riverside weather forecast all week, and if you’re stocking up for outdoor time, check out outdoor gear deals — including the UPF 50+ Fishing Shirts for $6.50 that are ideal sun protection for long afternoons in the valley sun.
