If you’ve lived in Davis for more than a single winter, you know the drill. You wake up to a wall of Tule fog so thick you can't see your own mailbox, only for it to burn off by noon into a day so blindingly sunny you’re reaching for your sunglasses. Predicting the davis weather 10 day forecast isn't just about checking an app; it’s about understanding the weird, temperamental microclimate of the Sacramento Valley.
Right now, as of January 15, 2026, we are sitting in a classic mid-winter pattern. The current temperature is a crisp 60°F, and honestly, it feels like the calm before a very specific kind of storm. While the sun is out today, the data tells a story of a shifting atmosphere that’s going to catch a few weekend warriors off guard.
The Immediate Outlook: Sunny With a Side of Chilly
Let's look at the next few days. Today, Thursday, we’re topping out at 62°F with a low of 37°F. That’s a 25-degree swing. If you aren't layering, you're doing it wrong. Friday looks like a carbon copy: a high of 62°F and a low of 37°F.
People always ask me why Davis gets so cold at night compared to, say, San Francisco. It’s the "Delta Breeze" in reverse. Without the ocean to moderate us, the heat just escapes into the atmosphere the second the sun goes down.
What the Next Week Actually Looks Like
By the time we hit the weekend, things start getting a bit more complicated. Saturday, January 17, brings in some cloud cover, though the high stays steady at 62°F.
But look at Sunday. The davis weather 10 day forecast shows a slight dip to 61°F and a 20% chance of rain. Now, 20% might not sound like much, but in the valley, that often translates to a gray, damp "mizzle" that doesn't quite wash your car but definitely ruins your bike ride.
Rain is Looming on the Horizon
Moving into next week, the temperatures start to compress. We’re looking at highs of 58°F from Monday all the way through Friday.
The humidity is also creeping up. We're talking 78% to 85% humidity levels by mid-week. When it’s 58 degrees and 85% humidity, it feels a lot colder than the thermometer says. It’s that damp, "gets-in-your-bones" kind of cold.
- Monday, Jan 19: Mostly sunny, high 58°F, low 38°F.
- Tuesday, Jan 20: Partly sunny, high 58°F, low 39°F.
- Wednesday, Jan 21: High 58°F, low 40°F, with persistent cloud cover.
- Thursday, Jan 22: High 58°F, low 43°F. This is the warmest night of the week because the clouds act like a blanket.
The Breakdown of the Final Days
By Saturday, January 24, we’re seeing the tail end of this 10-day window. The high drops to 57°F and the low holds at 40°F.

Wait, is it going to pour? Probably not. The precipitation chances for most of next week hover around 10% to 20%. It’s more of a "bring an umbrella just in case" situation than a "sandbag your garage" situation.
Why the Valley Fog Changes Everything
You can’t talk about Davis weather without talking about the fog. This time of year, we are in the heart of fog season.
Historically, January is our cloudiest month. Data from the UC Davis Arboretum shows that we only get about 9.8 hours of clear skies per day on average this month. If you’re planning a photography session or a long hike, you basically have a four-hour window between the fog lifting and the sun setting at 5:10 PM.
Expert Tips for Davis Survivors
If you're new to town or just a student trying to navigate campus, here’s the reality. The wind is currently coming from the North/Northeast at about 4 to 6 mph. That’s barely a breeze, but it’s enough to make a bike ride feel twice as hard if you’re heading toward Woodland.

Pro-tip: Check the UV index. Even on these "sunny" 60-degree days, the UV index is around 2. You won’t burn, but your plants might still be confused. According to the Old Farmer's Almanac, now is actually the time to start seeds for things like Bell Peppers and Leeks indoors, despite the chilly nights.
Actionable Next Steps for the Week Ahead
Don't let the 62-degree highs fool you into thinking spring is here. It’s a trap.
- Check your tire pressure: The drop to 37 degrees at night will likely trigger your "low tire pressure" light. Don't panic; it’s just physics.
- Layer for the bike commute: If you’re riding at 8 AM, it’s 39 degrees. If you’re riding home at 3 PM, it’s 62. You need a windbreaker that stuffs into a backpack.
- Water your outdoor pots: Even with the humidity, these north winds can dry out container plants surprisingly fast.
- Plan for the gray: Sunday and Monday will be the most depressing days of the week, visually speaking. Save your indoor chores for then.
Stay warm, keep your lights on while biking through the fog, and remember that a 10-day forecast is a suggestion, not a promise.
