Honestly, if you've lived in New York long enough, you know that "mostly cloudy" is basically the official uniform of January. You check your phone, see a gray icon, and assume it’s just another gloomy hump day.
But Wednesday, January 21, 2026, is shaping up to be a bit more nuanced than that. We aren't looking at a "Snowpocalypse" like the one Mayor Zohran Mamdani was prepping us for last weekend, but don't go leaving your scarf at home just because the sun peeks out for ten minutes.
The Wednesday Breakdown: NYC Weather Wednesday Hourly
The vibe for Wednesday is basically a slow fade from morning brightness into a dense, gray evening. It's the kind of day that starts out promising and ends with you questioning your life choices as you wait for the L train.
Here is how the numbers actually look:

Midnight to 5 AM: The Deep Freeze
If you’re a night owl or heading to an early shift at the Fulton Fish Market, prepare for the bite. We’re starting the day at a crisp 18°F, but with the wind coming off the water, it’s going to feel like 8°F.
6 AM to 11 AM: Morning Deception
This is the "golden hour" for Wednesday. You'll actually see some sun. The sky starts clear, but by 9 AM, those high-altitude wisps begin to roll in. Temperatures will struggle to climb, hovering in the low 20s.
12 PM to 4 PM: The Afternoon Peak
We hit our high of 34°F right around mid-afternoon. The clouds are moving in fast now, though. By 2 PM, the "some sun" from earlier is pretty much history. The wind is staying steady from the Southwest at 10 to 15 mph, so it never really feels "warm," even at the peak.

5 PM to Midnight: The Gray Descent
Commute time is going to be mostly cloudy. The mercury drops back down toward 28°F by the time most people are grabbing dinner. While there’s a tiny 10% chance of a stray snow flurry, it’s not the kind of stuff that sticks. It’s just... there.
Why "High" and "Low" Numbers Lie to You
Most people look at a high of 34°F and think, "Oh, it's above freezing, I'm good."
Kinda.

In NYC, the "RealFeel" is the only metric that matters because of the wind tunnels created by the skyscrapers. With a 15 mph wind, that 34°F feels significantly sharper. You’re essentially walking through a giant outdoor refrigerator.
Also, keep an eye on the humidity. It’s hovering around 60%, which in the winter means the air has that "damp cold" quality. It gets into your bones way faster than a dry cold does. If you’re planning a walk through Central Park, you’ve definitely got to layer up more than the thermometer suggests.
Survival Tactics for Wednesday
- The Layer Strategy: Start with a base layer. Even if you're just going to the office, that 8-degree wind chill in the morning will wreck you if you only have a dress shirt under a wool coat.
- Moisturize: The dew point is sitting at a measly 5°F. That is incredibly dry. Your skin and lips will feel like sandpaper by 3 PM if you don't prep.
- Footwear: There’s no major snow expected (only that 10% dusting), so you don't need the heavy-duty Sorels. However, the ground is still cold from the previous weekend’s 1-to-3-inch accumulation. Standard leather boots or thick-soled sneakers are the play.
Basically, Wednesday is a "high-effort, low-reward" weather day. It isn't pretty enough to be a winter wonderland, and it isn't warm enough to be comfortable. It’s just New York in January doing its thing.
Next Steps:
Since the UV index is a flat 1, you can skip the sunscreen, but keep an eye on the wind gusts. If you're near the West Side Highway, expect those 15 mph winds to feel much punchier. Check the subway transit apps before you head out, as the freezing morning temps can occasionally cause some signal delays on the older lines.
