If you’ve spent any real time in the Inland Empire, you know the weather here has a mind of its own. Honestly, most people look at a "Moreno Valley 10 day forecast" and expect standard California sunshine, but January 2026 is throwing us a few curveballs that might mess up your weekend plans if you aren't paying attention.
Right now, Moreno Valley is sitting at a surprisingly warm 76°F. It’s mostly sunny with a light breeze coming out of the east at 3 mph. It feels more like a late spring afternoon than the dead of winter. But don't let that fool you into thinking the whole week is going to be a t-shirt-and-shorts kind of deal.
The Immediate Breakdown
Today, Saturday, January 17, we’re hitting a high of 76°F. It’s partly sunny, but things start to shift as the sun goes down. Expect the clouds to roll in tonight with a low of 52°F. There’s a tiny 10% chance of rain, so you might see a stray drop or two, but it's nothing to cancel your dinner plans over. The wind is picking up a bit from the north at 8 mph.
Tomorrow, Sunday, January 18, looks pretty similar. We’re looking at 75°F for the high and 53°F for the low. It’ll be mostly sunny during the day. Again, there's that nagging 10% chance of daytime rain, though the night should stay dry.
Looking Into Next Week
Basically, the first half of next week is going to be gorgeous if you like crisp, clear winter sun.
- Monday, Jan 19: High of 75°F, low of 48°F. Totally sunny.
- Tuesday, Jan 20: High of 73°F, low of 48°F. Still sunny.
- Wednesday, Jan 21: High of 71°F, low of 48°F. Sunny during the day, but it turns cloudy at night.
Notice how those overnight lows are dipping into the 40s. That’s the classic high-desert-adjacent cooling effect we get here. You’ll definitely want a real jacket if you’re heading out for a late-night run to the grocery store.
The Big Shift: Rain is Coming
Here is where the Moreno Valley 10 day forecast gets interesting. Around the middle of next week, the temperatures start to tumble. By Friday, Jan 23, we drop to 63°F. That’s a 13-degree difference from where we are today.
Then comes Saturday, January 24. This is the day to keep an eye on. We’re expecting light rain both day and night with a high of only 62°F and a low of 46°F. The humidity is going to jump up to 66%. It’s going to feel damp and chilly, a total 180 from the current warmth.
The clouds hang around for Sunday, Jan 25 (high of 64°F) before we start to see the sun again on Monday, Jan 26. By the end of this 10-day stretch on Tuesday, Jan 27, we should be back up to a comfortable 70°F under sunny skies.

What You Should Actually Do
Kinda feels like two different seasons packed into one week, right? If you’re planning a hike at Box Springs Mountain, try to get it in before Thursday. Once that Friday/Saturday front hits, the trails are going to be slick and the visibility will tank.
Honestly, the biggest mistake people make is forgetting how fast it cools down once the sun drops behind the hills. Keep a hoodie in the car. You’ll be glad you have it when that 52°F or 48°F night air hits.
Take advantage of the sun through Wednesday for any outdoor chores or car washing. Once Saturday hits, the rain chance jumps to 25%, which isn't a monsoon, but it's enough to spot up your windshield. Keep an eye on the north winds today; 8 mph isn't huge, but it can make it feel a lot cooler than the thermometer says.
