Honestly, if you’ve lived in the Tri-Valley for a while, you know that "winter" here is a bit of a moving target. Some years we're basically drowning in atmospheric rivers, and other years it’s just crisp, dry, and surprisingly bright. Right now, looking at the 10 day weather dublin ca forecast, we are firmly in that second camp.
It’s January 14, 2026. While the East Coast is reportedly bracing for some sort of "Arctic revenge," we’re out here in Dublin practically wondering if we can get away with wearing shorts for an afternoon walk.
Seriously.
The Immediate Forecast: A Weirdly Warm January
If you’re checking the 10 day weather dublin ca right this second, the first thing you’ll notice is the sun. It’s everywhere.
For the next few days—Wednesday, Thursday, and Friday—we are looking at highs hitting about 62°F or even 65°F. That is significantly warmer than our historical average for mid-January, which usually hovers closer to 58°F.
- Wednesday (Today): Sunny, high of 62°F. Light breeze from the east.
- Thursday: Still sunny. Maybe a degree warmer.
- Friday: The streak continues. Highs near 63°F.
But don't let the afternoon sun fool you. This is still the high desert-adjacent climate of the valley. Once that sun dips behind the hills toward Hayward, the temperature drops like a stone. We’re talking lows in the low 40s, sometimes touching 39°F. If you’re heading to the Regal at Hacienda Crossings for a late movie, bring the heavy jacket. You'll need it when you walk back to the car.

What’s Happening Over the Weekend?
Saturday, January 17, is where things get a tiny bit "moody," though not much. We’re expecting some periodic clouds.
There’s a tiny chance of rain—maybe 5%—which in California terms basically means "don't bother washing your car." The high will stay steady around 62°F.
Sunday is looking like a carbon copy of the earlier part of the week. Clear skies, crisp air, and perfect conditions for a hike at Iron Horse Trail or a quick trip over to the premium outlets before the Monday rush.
The Mid-Term Shift (Days 6-10)
Around Monday, January 19, and Tuesday, January 20, the pattern starts to shift a little. We’ve been stuck in this "January Thaw" that the National Weather Service guys have been talking about, but the ridge of high pressure is going to weaken.
By next Wednesday and Thursday (Jan 21-22), we’ll see:
- More cloud cover: Increasing to about 50-60%.
- Slightly lower highs: Dropping back down to the 58°F range.
- Humidity bumps: It’ll feel a bit more "damp" even if it’s not pouring.
Is a massive storm coming? Probably not in this 10-day window. The models show a lot of that moisture getting sucked up by the Pacific Northwest. We might see a few sprinkles toward the end of next week, but nothing that’s going to trigger a flood watch.
Why Does Dublin Feel Different Than Pleasanton or San Ramon?
It’s the "gap."

Dublin sits right at the mouth of the Hayward Pass. When the wind picks up, it really moves through here. If the forecast says 5 mph, it often feels like 10 mph near Tassajara.
In January, that wind is usually coming from the north or northeast. It’s dry. It’s biting. Even on a 60°F day, if you’re standing in the shade with that breeze hitting you, it feels ten degrees colder. Local meteorologists often point out that the Tri-Valley acts like a bowl; the cold air settles in at night, which is why we get those frosty windshields even when San Francisco is staying a balmy 50°F.
Historical Context: Is This Normal?
Actually, January 2026 is trending about 6°F warmer than last year across the U.S. West.
Last year, the first three weeks of January were pretty brutal. This year? It’s a wholesale change. We’re seeing what some call a "headwind" for winter clothing retailers because nobody needs a parka to go to Whole Foods right now.
Practical Tips for the Next 10 Days
Since the 10 day weather dublin ca is looking so consistent, you can actually plan ahead.

Layer like a pro.
You need a light base layer for the 2:00 PM sun and a legit wool coat or puffer for the 7:00 AM commute. The "feels like" temperature is going to swing by 25 degrees every single day.
Water your garden.
Because we aren't getting the usual January soaking, your perennials might actually be thirsty. Check the soil. If it’s bone dry two inches down, give them a drink.
Allergy Alert.
The warmer weather in the West is triggering early tree pollen. If you’re a "Cedar Fever" sufferer or generally sensitive, you might want to start your antihistamines now. Texas is already seeing a spike, and California isn't far behind.
Outdoor Projects.
If you’ve been waiting to paint a fence or fix a roof leak, this is your window. From now through January 22, the chance of significant precipitation is hovering around 10% or less. You won't get a better stretch of dry weather until April.
What to Watch Out For
The Polar Vortex is the big wildcard.
While the 10 day weather dublin ca looks stable now, the upper atmosphere is doing some weird stuff. The vortex is weakening, which usually means cold air starts "leaking" south. For now, it’s mostly hitting the East and the South. But keep an eye on the forecast for the final week of January. If that cold air shifts west, we could go from 65°F to freezing overnight.
For the next ten days, though? Enjoy the sun. It’s a classic California winter gift.
Stay updated by checking the local stations at Livermore Municipal Airport, as they usually have the most accurate "real-time" data for our specific slice of the valley. Avoid the generic "San Francisco" forecasts—they don't account for the hills, and they'll always tell you it's cooler than it actually is in Dublin.
Take advantage of the dry Friday to clear out your gutters before the pattern inevitably flips in February. Stock up on allergy meds if the wind starts picking up from the north. Most importantly, keep a spare jacket in the car; that 40-degree drop at sunset happens faster than you think.
