You're looking at the 10 day forecast for oakland ca and thinking it's just another week of "mild with a side of fog," right? Honestly, that’s where most people mess up. They see the numbers and assume it’s steady, but late January in the Town is a weird, shifting beast.
One minute you’re walking Lake Merritt in a light hoodie, and the next, a damp wind kicks up off the estuary and suddenly you’re shivering.
The Real Deal on the Next 10 Days
Right now, as of Sunday, January 18, 2026, we’re sitting at a crisp 51°F with a northeast wind that’s barely a whisper at 4 mph. But don't let the "partly sunny" label fool you. This week is basically a slow slide from decent outdoor weather into what the old-timers call "real winter" (or as real as it gets in the East Bay).
Today is actually the peak. We’re hitting 63°F, which is pretty solid for mid-January. If you've got laundry to hang or a dog that needs a long run at Joaquin Miller, do it now. Monday stays in that 63°F range, but the clouds start thickening up. It's that classic Oakland gray that feels like a heavy blanket.
By the time we hit Tuesday and Wednesday, the highs dip slightly to 62°F. You'll notice the night-time lows hanging around 46°F or 47°F. That’s the range where your heater starts kicking on at 3:00 AM.

Why the Microclimates Matter
Oakland isn't just one weather zone.
If you’re down in Jack London Square, you’re getting that direct bay influence. Up in the Montclair hills? You might be five degrees cooler and shrouded in mist while the Fruitvale is basking in a lucky sun patch.
Around Friday, January 23, things get a bit moodier. We’re looking at a high of 58°F and a 15% chance of rain. That doesn't sound like much, but in the Bay Area, a "15% chance" often means a persistent, annoying drizzle that makes the 880 a nightmare.
Saturday, January 24, looks like the coolest day of the stretch.
- High: 57°F
- Low: 47°F
- Rain Chance: 20%
- Humidity: 73%
That 73% humidity is the kicker. It’s that "bone-chilling" dampness. It’s not "cold" like Chicago is cold, but it's a wet cold that finds the gaps in your jacket.
The Long View: January 25 through January 27
As we wrap up this 10-day window, the sun tries to make a comeback. Sunday the 25th holds at 57°F, but by Monday the 26th, we’re creeping back up to 60°F.
Historically, January is our coldest month. We average a high of 58°F, so this particular 10-day stretch is actually trending slightly warmer than the 30-year average. We aren't seeing any massive "Pineapple Express" atmospheric rivers in this specific window, which is a relief for anyone with a leaky roof or a basement in the flats.
What You Should Actually Do
Don't trust the "mostly sunny" icons for the whole week.
Basically, you’ve gotta layer. It’s the cliché California advice because it’s the only thing that works. The difference between the 63°F high on Sunday and the 47°F low on Monday night is enough to ruin your plans if you aren't prepared.
If you're planning any outdoor events, the window between now and Wednesday is your best bet. After that, the "chilly" factor increases significantly.

Keep an eye on the wind direction. When it flips to the southwest on Friday, that's usually the signal that the moisture is moving in from the Pacific.
Actionable Next Steps:
- Check your gutters before the slight rain chances increase toward the weekend.
- Plan outdoor errands for Monday while the temps are still in the low 60s.
- Grab the heavy coat for any evening plans starting Friday, as the humidity and lower temps will make the 40s feel much colder.
