Riverside–San Bernardino is easing into a mild, mostly sunny Friday with a high near 73°F — the most comfortable day of the stretch before Memorial Day weekend heat kicks in. If you’ve been itching to hit Mount Rubidoux or get in a round at a local course, this afternoon is your window.
Today’s Setup
The National Weather Service notes a deep marine layer is still sitting around 5,000 feet this morning, with a few stray light showers possible over the foothills and mountain slopes before noon. Rainfall will be minimal — a few hundredths of an inch at most — and skies should clear across the Inland Empire valley by midday. West winds build to 0–15 mph by afternoon with gusts near 25 mph, so secure any patio umbrellas before heading out. Today’s 73°F high is running 12–18 degrees below late-May averages for the mountains, per the National Weather Service — that’s genuinely pleasant weather for the region.
Best Window To Be Outside
Friday afternoon from noon through early evening is your sweet spot. Pack a picnic basket set for 4 and head to Fairmount Park or Sycamore Canyon Wilderness Park while conditions are still comfortable. Golfers, this is a gift before the heat arrives. Looking ahead to Saturday and Sunday? A slip and slide in the backyard is going to get plenty of use as temps push into the 80s.
Concerts, Comedy, and Game Day
Tonight, May 29: Pitbull and Lil Jon bring “I’m Back” to the North Island Credit Union Amphitheatre. By showtime, temps will settle into the mid-60s with a light marine breeze — comfortable but worth layering up. Grab last-minute seats with Get tickets on SeatGeek or Find tickets on StubHub. A Pitbull t-shirt is perfect for the warm early set; bring a Pitbull hoodie once the night air drops.
Saturday, May 30: The Los Angeles Dodgers host the Philadelphia Phillies at Dodger Stadium under sunny skies near 82°F — about as good as baseball weather gets in Southern California. Check the full gameday forecast and don’t leave home without your Los Angeles Dodgers jersey or a Los Angeles Dodgers fitted cap for sun protection in the bleachers. The series continues Sunday, May 31.
Also Saturday: Jeff Dunham headlines the Los Angeles County Fair in Pomona — outdoor evening conditions should be comfortable in the upper 70s.
Sunday, May 31, MANÁ: VIVIR SIN AIRE TOUR plays Acrisure Arena at Greater Palm Springs as the desert warms into the mid-80s.
Allergy and Air Quality Watch
Breezy post-marine-layer afternoons can kick up pollen and fine particulates across the Inland Empire. If grass or tree pollen has been bothering you, running a HEPA air purifier at home keeps indoor air cleaner during windy stretches.
Dinner Tonight
Tonight’s mild temps call for something light and quick — a pasta primavera or a veggie stir-fry comes together fast and leaves plenty of energy for the weekend. You can order groceries on Amazon and have everything delivered before dinnertime.
Next Few Days
Saturday reaches near 82°F under full sunshine — a standout day for the whole region. Sunday climbs a few degrees higher, running around 5 degrees above average per the National Weather Service. Into next week, inland areas including the San Bernardino Valley could see highs 4–8 degrees above seasonal average. No rain is in the forecast through at least next Thursday. Big Bear and Joshua Tree trips are in great shape — just bring extra water as summer heat arrives in earnest.
