You’ve probably seen the movies. The ones where someone is ice skating at Rockefeller Center while giant, fluffy snowflakes drift down in slow motion. It looks magical. Kinda perfect, honestly.
But if you’re actually planning to be here, the reality of weather in ny for december is a lot messier. Literally.
Most people expect a winter wonderland from day one. Instead, they usually get a damp, gray slush-fest that requires a specific kind of tactical footwear. New York in December is a transitional beast. It’s the month where the city tries to decide if it’s still autumn or if it’s time to unleash the arctic tundra.
The Temperature Rollercoaster
Don't let the "average" numbers fool you. While the National Weather Service (NWS) tells us the average high is around 44°F and the low is 34°F, those numbers are basically just a suggestion.
In early December, you might catch a "warm" day where it hits 55°F. You’ll see locals walking around with their coats open, looking hopeful. Then, 24 hours later, a cold front screams down from Canada and you’re shivering in 28°F wind chills.
The wind is the real killer. Between the skyscrapers, the wind tunnels are brutal. If the forecast says 35°F, it feels like 20°F the moment you turn a corner onto an avenue.

Does it actually snow?
Statistically? Not as much as you’d think.
For the weather in ny for december, we usually see about 4.9 inches of total snowfall for the month. But here’s the catch: it rarely stays pretty. Because of the "Urban Heat Island" effect, the snow often turns into a brownish-gray liquid known locally as "slush puddles of doom."
You'll see a pristine white patch of snow on a park bench, and three feet away, a six-inch-deep lake of freezing melted ice waiting to ruin your suede boots.
According to data from Central Park’s weather station, we’ve had plenty of Decembers with almost zero snow. Conversely, a Nor’easter can occasionally dump 10 inches in one night. It’s a total gamble.
Rain is the silent protagonist
Honestly, you’re more likely to deal with rain than snow.

December is one of the more humid months in New York. You get these misty, drizzly days that aren't quite "storms" but just enough to make the subway stairs slippery and your hair a mess.
- The Dampness Factor: Cold rain at 38°F feels significantly colder than dry air at 25°F.
- The Umbrella Trap: If it’s windy, don’t bother with a cheap street-corner umbrella. It will flip inside out in approximately four seconds.
- The Humidity: Average relative humidity sits around 62% to 65%. It’s a "wet" cold that gets into your bones.
What to actually wear
If you want to survive the weather in ny for december without looking like a shivering tourist, you need to master the art of the layer.
New York buildings are notoriously overheated. You will go from a freezing street corner into a 75°F department store or a humid subway station. If you’re wearing one giant, heavy sweater under a parka, you’re going to sweat.
The Survival Kit:
- Waterproof boots with grip: Forget the fashion heels or sneakers. You need something that can handle a 3-inch deep slush puddle.
- Uniqlo Heattech (or similar): Thin thermal layers are the secret weapon of every local.
- The "Big Coat": A long parka that covers your thighs is better than a short jacket. It blocks the wind from hitting your legs.
- Gloves with touch-screen fingers: You’ll be using Google Maps a lot. Taking your gloves off every time you need to find a bagel shop is a mistake you’ll only make once.
Daylight (or lack thereof)
The sun sets early. Really early.
By mid-December, it’s dark by 4:30 PM. This changes the vibe of the city completely. The holiday lights look great, but the temperature drops the second the sun dips behind the buildings.
If you’re planning a walk across the Brooklyn Bridge, do it at 3:00 PM. By 4:45 PM, that bridge is a freezing wind-swept gauntlet.
Is it worth it?
Despite the gray skies and the slush, there’s a reason people flock here. The air feels crisp, the smell of roasted nuts is everywhere, and when the sun does hit the skyline on a clear, cold day, it’s stunning.
Just don't expect a movie. Expect a bit of a battle with the elements.
How to handle the December elements like a pro
- Check the "RealFeel": Never look at the base temperature; always check the wind chill or "RealFeel" on your weather app. That's the number that actually matters.
- Avoid the "Curb Lakes": When crossing the street after a snow or rain, stay away from the corners. The sewer grates clog, and the deepest water collects right where you're supposed to step off the sidewalk.
- Carry a small bag for layers: You’ll want a place to stuff your scarf, hat, and gloves once you get inside a museum or theater so you don't lose them.
- Moisturize: The combination of biting wind and dry indoor radiator heat will wreck your skin. Pack a heavy-duty lip balm.
The best way to prepare for New York's December weather is to assume it will change three times in the same afternoon. Wear the waterproof boots, pack the thermal shirt, and keep a positive attitude when the wind tries to blow you toward Jersey.
