You’ve heard the rumors about New York in January. People say it’s just a gray, slushy purgatory where the wind tunnels between skyscrapers try to steal your soul. Honestly? They aren't entirely wrong, but they’re missing the point.
Right now, if you step outside in Manhattan, you’re hitting a wall of 31°F air. The humidity is sitting at a heavy 91%, and there’s a light snow falling that feels more like a cold mist than a postcard. It’s Sunday, January 18, 2026, and the 10 day new york weather outlook is basically a masterclass in why you need to pack layers, not just a big coat.
The Immediate Mess: Snow and "The Dip"
We are currently staring down a heavy snow storm for the rest of today. The high is struggling to reach 35°F, and by tonight, we’re looking at a low of 23°F. There’s an 86% chance of snow during the day. If you’re planning to take the L train or walk across the Brooklyn Bridge, maybe don’t.
Monday, January 19—Martin Luther King Jr. Day—is going to be a "fake out" day. It’ll be sunny with a high of 32°F, but the low is going to plummet to 15°F. That’s the kind of cold that makes your phone battery die in twenty minutes.

Why Tuesday is the Real Boss
If you think Monday sounds rough, Tuesday, January 20, is the real reality check. We’re looking at a high of only 21°F and a low of 14°F. It’ll be sunny, sure, but that’s "refrigerator light" sun—it looks bright, but it provides zero warmth. Wind speeds will be kicking around 13 mph from the west, making that 21°F feel significantly more aggressive.
mid-Week Muck and the 40-Degree Tease
By Wednesday, January 21, the city starts to "warm up," if you can call 34°F warm. It’ll be mostly cloudy, and the low stays parked at 14°F.
Then comes Thursday. Thursday is the day New York tries to apologize. We’re hitting a high of 40°F. It sounds like nothing, but after a 14-degree night, 40°F feels like a tropical vacation. New Yorkers will literally start wearing light denim jackets and sitting outside at coffee shops. Don't be fooled. The sun will be out, but that low of 23°F is still waiting for you the second the sun ducks behind a building.

The Back Half: More Gray, More Bricks
Friday, January 23, through the following Tuesday is a slow slide back into the freezer:
- Friday: Mostly cloudy, high of 33°F.
- Saturday: Partly sunny, high drops to 25°F. The low? A brutal 7°F.
- Sunday, Jan 25: Mostly cloudy with snow showers at night. High of 22°F, low of 6°F.
- Monday, Jan 26: A 75% chance of actual snow. High of 22°F, low of 11°F.
That Sunday night into Monday stretch looks like the next real "event." If you're traveling, keep an eye on the northwest winds, which are forecasted to hit 21 mph on Monday. That’s enough to turn a light snowfall into a blinding sideways mess.
What Most People Get Wrong About NYC Winter
People think the temperature is the enemy. It’s not. It’s the wind and the "brick." In New York slang, when it's "brick," it means it's cold enough to crack a stone.

The skyscrapers create venturi effects. A 10 mph wind in the forecast becomes a 30 mph gust when it’s squeezed between two glass towers on 6th Avenue. This is why your 10 day new york weather app can say 30°F, but your face tells you it's 10°F.
Also, the "slush puddles." They look like solid ground. They are actually six-inch deep reservoirs of freezing gray Gatorade. If you aren't wearing waterproof boots, your day is over.
Actionable Survival Steps
- The 3-Layer Rule: A moisture-wicking base (no cotton!), a sweater or fleece, and a windproof shell. If you skip the windproof layer, the rest doesn't matter.
- Watch the Lows: The "high" temperature usually only lasts for about two hours in the afternoon. Base your outfit on the low, because that’s what you’ll feel in the shadows.
- Battery Management: Keep your phone in an internal pocket close to your body heat. Frigid temps like the 6°F we’re seeing next Sunday will tank a lithium battery fast.
- Hydrate: You don't feel thirsty when it's 20°F, but the dry air and heaters will dehydrate you faster than a summer day in Jersey.
Basically, the next ten days are going to be a rollercoaster of "pretty snow" and "get me inside right now." Tuesday and next Sunday are the days to stay in and order a bagel. For the rest? Just keep your head down and your scarf up.
