Honestly, if you're standing on Michigan Avenue right now, you already know the answer isn't just a number. It's a mood.
As of mid-afternoon on Saturday, January 17, 2026, the temperature in Chicago is 18°F. But that’s the "official" reading at the airport. If you actually step outside, you’re dealing with a feels-like temperature of 4°F. That’s the real story. The wind is biting. It’s coming out of the west at about 14 mph, which is just enough to make your eyes water if you're walking against it.
The Breakdown of What's Happening Now
Right now, it’s just plain cloudy. There was some light snow earlier, and we’re still looking at a tiny 10% chance of a few more flakes drifting down before the sun sets. The humidity is sitting at 53%, and the UV index is basically non-existent. You won't be needing sunglasses for the glare today.

Chicago weather is famously moody, but today is being remarkably consistent in its chill. We're looking at a high of 19°F and a low of 14°F for the full 24-hour cycle.
Why the Wind Chill is the Real Boss Today
A lot of people check their phone, see 18 degrees, and think, "I can handle that." Then they walk out in a light jacket and realize they’ve made a massive mistake. When the wind hits 14 or 16 mph in this city, that 18-degree air starts acting like it’s in the single digits.

West winds are sweeping across the flat Illinois landscape and funneling between the skyscrapers. It creates those localized wind tunnels that can knock the breath out of you. If you’re heading to a Bulls game or just grabbing a coffee, layers aren't a suggestion—they're a survival strategy.
What to Expect for the Rest of Tonight
As we move into the evening, things aren't exactly warming up. The light snow chance actually bumps up a bit to 20% tonight. It’s not going to be a blizzard, but enough to make the sidewalks a little slick.

Survival Tips for 18-Degree Weather
If you've gotta be out, cover your face. That 4-degree wind chill is prime territory for chapped skin. Also, watch the bridges. Even if the main roads look clear, the overpasses and bridges over the Chicago River freeze way faster because they have cold air hitting them from both the top and the bottom.
Honestly, it's a great day to stay inside, order some deep dish, and wait for the sun to eventually make an appearance—whenever that may be.
Actionable Next Steps:
If you are planning to drive anywhere tonight, check the local salt trucks' progress on the city's plow tracker, as that 20% chance of snow could create "black ice" patches on side streets. If you're walking, stick to the Pedway if you can to avoid the 4°F wind chill altogether.
