Honestly, if you stepped outside in Dublin this morning, you probably noticed it right away. That bite in the air? It's there, but it's not quite the freezing "Valley chill" we usually expect for mid-January.
Dublin CA weather today is putting on a bit of a show. While the rest of the country might be shoveling snow or hiding under parkas, we’re looking at a day that feels more like early spring than the dead of winter. It’s clear, it’s crisp, and frankly, it’s a perfect day to be out at Emerald Glen Park.

The Numbers You Actually Care About
Let's talk specifics. If you're heading out the door right now, the current temperature is sitting at 42°F. It’s chilly, sure. But with the wind barely moving—coming in from the northeast at just 2 mph—it doesn't have that "cut through your bones" feeling.
As the day progresses, we're going to see a significant jump. We are hitting a high of 66°F today. That’s a 24-degree swing!
You've gotta love the Tri-Valley microclimates. You leave the house in a heavy coat and by 2:00 PM, you're regretting every life choice that led to wearing wool.
- Current Condition: Clear skies
- Today's High: 66°F
- Tonight's Low: 40°F
- Rain Chance: 0% (Basically zero)
- UV Index: 2 (Low, but don't let the cool air fool you if you're fair-skinned)
Why Is It So Dry?
People keep asking where the rain went. January is usually our "wet" month, right? Historically, Dublin sees about 3.3 inches of rain throughout January. But today? Not a drop.
According to the latest data from the Old Farmer’s Almanac and local stations at Livermore Municipal Airport, we are in a high-pressure ridge. This "Omega Block" is essentially acting like a giant umbrella over Northern California. It pushes the storm tracks up into the Pacific Northwest, leaving us with these sapphire-blue skies and zero percent precipitation.
Humidity is hanging around 81% this morning, which is why your windshield might have had a thin layer of frost. But that's going to drop to around 64% by this afternoon as the sun does its thing.
Dressing for the Dublin "Layer Game"
If you've lived here long enough, you know the drill. You don't just "wear an outfit." You build a modular survival system.
Start with a light base. A t-shirt is fine because 66°F in the direct sun feels more like 70°F. Throw a medium-weight fleece or a light puffer over that for the morning. By the time you’re grabbing lunch at Persimmon Place, that jacket is going in the backseat.
The wind is the wild card. Today it’s staying calm, mostly northeast at 5 mph this afternoon. It’s just enough to keep the air from feeling stagnant but not enough to ruin a hair day or make your outdoor patio coffee feel like a mistake.
What This Means for Your Weekend
The dry spell isn't just a today thing. This clear, sunny pattern is holding steady.
Looking ahead to Saturday and Sunday, we’re staying in that mid-60s sweet spot. This is rare for 2026. Usually, by mid-January, we're dealing with "Atmospheric Rivers" and soggy lawns. Take advantage of it.
Actionable Next Steps:
- Check your tire pressure: These big temperature swings from 40°F to 66°F can trigger your TPMS light.
- Hydrate your plants: Since we aren't getting rain, your garden is probably thirstier than it looks.
- Plan an outdoor activity: Hit the Iron Horse Trail today before the next cooling trend arrives late next week.
