Honestly, trying to pin down a 10-day weather forecast for Oakland can feel a bit like trying to predict which way a cat is going to jump. We’ve all been there: you check your phone in the morning, see a little sun icon, and by 2:00 PM you're ducking into a coffee shop on Grand Avenue because the fog rolled in faster than a Golden State fast break. But looking at the current data for mid-January 2026, things are actually looking surprisingly steady, if a bit chilly for the Town.
The Immediate Vibe: What’s Happening Now
Right now, as of Sunday, January 18, it’s about 62°F out there. It’s that classic "partly sunny" Northern California winter day where you feel great in the sun but reach for a hoodie the second you hit the shade. We’ve got a light breeze coming from the northeast at about 4 mph, which isn't enough to mess up your hair but keeps the air feeling crisp. Humidity is sitting at 59%, so it’s not that bone-dry air that makes your skin itch, but it’s definitely not muggy either.
If you’re heading out for a walk around Lake Merritt tonight, just a heads up—the temperature is going to dip down to 45°F. That’s basically the floor for the next few days. We’re also seeing about a 10% chance of rain tonight and tomorrow, which in "Oakland speak" usually just means some heavy mist or a light drizzle that barely wets the pavement.

The 10-Day Outlook: Breaking Down the Numbers
When you look at the 10 day weather forecast for Oakland, you start to see a pattern. We aren't hitting those wild 70-degree winter spikes right now, but we aren't freezing either. It’s a very consistent, mid-range stretch.
Basically, the high temperatures are going to hover between 56°F and 63°F through late January. Tuesday and Wednesday (Jan 20-21) look like they’ll be the "coldest" days, with highs only reaching about 57°F or 58°F under pretty heavy cloud cover. If you’ve got outdoor plans, Friday the 23rd is looking like your best bet for actual Vitamin D, as it’s currently forecasted to be full-on sunny with a high of 57°F.

A Quick Peek at the Day-to-Day
- Monday (Jan 19): Mostly a repeat of today. High of 61°F, low of 45°F. A bit more cloud cover moving in by the evening.
- Tuesday & Wednesday (Jan 20-21): This is the "grey stretch." Expect solid clouds. Highs will struggle to break 58°F. Humidity jumps up to around 80%, so it’ll feel a bit damper even if it doesn't dump rain.
- Thursday (Jan 22): The sun starts peeking back through. We’re looking at 57°F with a slight breeze from the west at 7 mph.
- The Weekend (Jan 24-25): Saturday stays mostly sunny (57°F/45°F), while Sunday brings the clouds back in. It’s a bit of a toss-up, but definitely keep the layers handy.
Why Oakland Weather is So Weird (The Microclimate Factor)
You can’t talk about the forecast here without mentioning the "Hills vs. Flatlands" divide. If you’re living up in Montclair or near Joaquin Miller Park, you’re almost certainly going to be a few degrees cooler than someone sitting at a bar in Jack London Square. The marine layer loves to snag on the Berkeley and Oakland hills, often dumping more moisture up there while the rest of the city stays dry.
Also, notice the wind direction in the forecast. Most of this week, the wind is coming from the North/Northeast. That’s key. Usually, our weather comes from the West (the Pacific). When it shifts to the North or East, it often brings drier, slightly more stable air, which explains why our rain chances are staying so low (mostly 5% to 10%) despite the heavy cloud cover predicted for mid-week.

Is Rain Actually Coming?
The short answer? Not really. While the 10-day forecast shows a few "cloudy" days, the actual probability of measurable rainfall is hovering around 10% for most of the week. In meteorological terms, that’s basically a "maybe, but don't count on it" scenario. If you're planning on washing your car, you're probably safe, though Tuesday might give you a few spots of "mist" if the humidity spikes as expected.
Survival Tips for an Oakland January
Since we’re dealing with a 63°F high and a 45°F low, you’re looking at an 18-degree swing every single day. That's the classic California struggle.
- The Layer Cake Method: You know the drill. A t-shirt under a light sweater, under a windbreaker or denim jacket. You'll likely be stripping layers off by noon and piling them back on by 4:30 PM when the sun starts its descent.
- Watch the UV Index: Even on the "partly sunny" days, the UV index is around 1 or 2. It’s low, but if you’re out hiking Redwood Regional for four hours, that winter sun can still catch you off guard.
- Humidity and Your House: With humidity hitting 88% on Thursday night, it's a good time to make sure your windows are sealed. Bay Area houses aren't exactly known for their world-class insulation, and that damp chill can really seep in.
Ultimately, the next 10 days in Oakland are going to be pretty "mid"—in a good way. No major storms, no heatwaves, just solid, chilly-but-fair East Bay winter weather.
Actionable Next Steps:
- Plan your outdoor activities (hiking, gardening) for Friday, Jan 23, which has the clearest "sunny" rating of the week.
- Keep a light rain shell in your car for the Tuesday/Wednesday window, just in case those 10% drizzle chances decide to overachieve.
- Check your tire pressure; those overnight drops to 45°F can cause your "low pressure" light to pop on if your seals are aging.
