Honestly, if you’re planning a trip to the valley or just trying to figure out if you can finally wash the car, the weather in Livermore 10 days from now is looking surprisingly steady. People always think January in the East Bay is just one big, soggy mess. Not this time.
Right now, as of Friday, January 16, 2026, we’re sitting at a crisp 51°F with a light northeast wind. It's actually pretty nice out there. But the real story is how the next week and a half is shaping up to be more about "sweater weather" than "umbrella weather."
The 10-Day Outlook: Dry Skies and Chilly Mornings
Basically, we’re looking at a high-pressure setup that’s keeping things remarkably dry. Today, we’re hitting a high of 64°F, which feels like a gift for mid-January. You’ve got clear skies tonight, but it’s gonna drop. Fast. We’re talking 38°F by morning, so don't let that afternoon sun trick you into leaving the heater off.
The trend stays pretty similar through the weekend. Saturday, January 17, brings some clouds—mostly cloudy during the day and fully cloudy at night—but the temperature holds at 64°F. There's a tiny 10% chance of rain, but honestly, it’s probably not even enough to spot your windshield. Sunday actually looks a bit brighter with partly sunny skies and a high of 65°F.
Monday and Tuesday (January 19-20) are looking like peak Livermore winter. Sunny to mostly sunny, highs around 63°F, and lows dipping back to 39°F. It’s that classic valley temperature swing where you need three different outfits just to get through the day.

What to Expect Mid-Week
As we roll into Wednesday, January 21, and Thursday, January 22, the clouds start creeping back in. We’re looking at partly sunny conditions with highs slowly cooling down to 62°F and 61°F. The lows will actually be a bit warmer, relatively speaking, staying in the low 40s because of that cloud cover acting like a blanket.
The end of the 10-day stretch—Friday, January 23 through Sunday, January 25—stays consistent. You’re looking at highs of 61°F and mostly cloudy skies. Rain chances stay low, around 5% to 10%, which is kind of wild for this time of year when we usually expect at least one decent storm.
Why the Livermore Valley Microclimate Matters
Livermore is a bit of a weird one. Unlike San Francisco or even Oakland, we don't get that immediate coastal cooling, but we do get the "Altamont effect." In January, that often means we trap the cold air in the basin.
According to data from the Western Regional Climate Center, January is typically our wettest month, averaging about 2.91 inches of rain. This year? We're bucking the trend. The current high-pressure ridge is blocking those Pacific storms, leaving us with these dry, sunny afternoons.

If you're heading out to the wineries or hitting the trails at Del Valle, you've got to dress for the transitions. The humidity is hovering around 67% to 73%, which makes that 38°F morning feel a lot bite-ier than a dry 38°F.
Breaking Down the Numbers (Prose Style)
For those who like the specifics, here is the breakdown of the weather in Livermore 10 days out. Today starts us at 64°F. Tomorrow and Sunday stay in that 64-65°F range. Monday through Wednesday we see a slight dip to 63°F and 62°F. By the time we hit the following weekend, we’re looking at a very consistent 61°F for Friday, Saturday, and Sunday.
Rain chances never really break the 10% mark throughout this entire period. Wind speeds are also staying very low, mostly 5 mph or less coming from the northeast or west. It’s basically very calm, very stagnant, and very typical "valley fog" potential weather, though the forecasts aren't calling for heavy Tule fog just yet.
What Most People Get Wrong About January Weather
Most folks assume that "mostly cloudy" in the winter means rain is coming. In Livermore, that’s not always true. Often, those clouds are just high-level marine layers or debris from storms passing way to the north.

Another misconception? That the UV index doesn't matter in the winter. Even with a UV index of 1 or 2, if you’re out on a three-hour hike at Sycamore Grove, you’re still getting sun exposure. It’s low, sure, but it’s there.
Also, don't trust the "high" temperature for your evening plans. In the summer, Livermore stays warm late. In January, the second that sun dips behind the hills, the temperature crashes. If you’re planning an outdoor dinner for next Tuesday when it’s 63°F, remember that by 6:00 PM, it’ll likely be in the 40s.
Planning Your Next Steps
Since it’s going to be dry and relatively mild, it’s actually a great time for yard work or outdoor projects that usually get sidelined by mud this time of year.
- Check your irrigation: With the lack of rain over these 10 days, some of your more sensitive plants might actually need a quick drink, even though it's winter.
- Layer up: Use the "base-mid-shell" approach if you're commuting. That 38°F morning needs a heavy coat, but you’ll want to be in a light sweater by 2:00 PM.
- Watch the overnight lows: If you have delicate succulents or potted lemon trees, keep an eye on those 38°F to 39°F nights. We aren't hitting hard freeze territory yet, but we're close enough to be cautious.
Bottom line: The weather in Livermore 10 days from now is looking exceptionally stable. It’s chilly, it’s dry, and it’s honestly pretty great for being outdoors, provided you have a good jacket handy. Enjoy the sun while it lasts, because February usually likes to make up for lost time when it comes to the rain.
