Riverside, CA starts Thursday, June 25 under patchy fog, but sunny skies and a high near 87°F are on the way — clear your morning plans for after 11 AM and the afternoon opens up beautifully. Check the Riverside weather forecast for daily updates as a notable cooling trend builds this weekend.
Today’s Setup
The National Weather Service is tracking a low pressure system moving in from the northwest, pushing stronger onshore flow across Southern California. For the Inland Empire, that translates to a high near 87°F today — actually a few to around 5 degrees below average for late June. West winds run 0 to 15 mph with gusts up to 25 mph this afternoon. Morning fog near Box Springs Mountain and the Jurupa Valley foothills should lift by 11 AM, then it’s wide-open sunshine through the evening.
Best Window To Be Outside
Once that fog clears, late morning through mid-afternoon is your sweet spot. Golfers at Jurupa Hills Country Club should tee off by 9 AM to get ahead of the heat. Hikers on the trails at Mount Rubidoux Park will find the temperature very manageable once skies clear. If you’re doing yard work, now’s a smart time to set up a soaker hose for garden beds before the weekend cooling makes conditions ideal for planting. Carry an insulated water jug 1 gallon on any outdoor outing — even a mild IE day can sneak up on you.
Rain, Wind, or Heat Risk
No red flags today — no excessive heat warning, no severe weather threat for the Inland Empire. The WPC’s moderate excessive rainfall risk is centered over Kansas and Missouri, nowhere near us. The bigger story locally is the cooling trend incoming. NWS forecasters note Saturday could run 10 to 15 degrees below average for inland valleys, with the Inland Empire seeing highs in the mid 70s to lower 80s. The marine layer deepens through Sunday, with patchy fog and possible light coastal drizzle extending well inland by early Sunday morning.
Angels Weekend Series — Prime Ballpark Weather
The Los Angeles Angels host the Athletics on Saturday, June 27 and Sunday, June 28 at Angel Stadium in Anaheim. With Saturday’s cooling trend bringing highs to the mid-to-upper 70s, this could be the most comfortable game-day weekend of the summer — no brutal heat, no storm threat. Grab a Los Angeles Angels jersey or Los Angeles Angels fitted cap to represent, and Find tickets on StubHub if you still need seats.
