It was late October. Most people in the city were busy arguing about the upcoming 2012 election or planning Halloween costumes. Then the sky turned a weird, bruised shade of purple. You probably remember the grainy cell phone footage of the Con Edison plant exploding on the East River, or the terrifying sight of seawater rushing into the Battery Park tunnel like a scene from a big-budget disaster movie. But if you’re looking for the specific calendar date of when did Hurricane Sandy hit New York City, the answer is October 29, 2012.
That Monday evening changed the city's DNA forever.
It wasn't just a storm. By the time it reached the Jersey Shore and veered into New York, it had technically been reclassified as a "post-tropical cyclone," but tell that to the people in Breezy Point who watched over a hundred homes burn to the waterline because fire trucks couldn't reach them through the flood. Sandy was massive. It was roughly 1,100 miles wide. For context, that’s about the distance from New York City to Jacksonville, Florida. When that much energy hits a shallow continental shelf during a high tide—and a full moon, no less—you get a recipe for a 14-foot storm surge that breaks every record in the books.
The Night Everything Went Dark
The timeline of when did Hurricane Sandy hit New York City really picks up speed in the late afternoon of October 29. Around 8:00 PM, the storm made landfall near Brigantine, New Jersey. But NYC was already feeling it. The surge didn't wait for the center of the storm. It pushed into New York Harbor, shoving billions of gallons of salt water into the streets of Lower Manhattan, Red Hook, and the Rockaways.
The power went out.

Not just a flicker. A massive, transformative darkness swallowed everything below 34th Street. If you were there, you remember looking south from Midtown and seeing... nothing. Just a black void where one of the most illuminated places on Earth used to be. The Con Ed explosion at the 14th Street substation happened right around 8:30 PM, and that was the signal for many that the "Superstorm" had truly arrived.
Honestly, the sheer speed of the flooding caught people off guard. We'd had Hurricane Irene the year before, and it was mostly a "fizzle" for the city. People got complacent. They stayed in their basement apartments in Queens. They didn't move their cars. Then, in a matter of an hour, the Atlantic Ocean was in their living rooms. According to the New York City Department of City Planning, Sandy damaged or destroyed about 69,000 residential units.
Why the Surge Was Different This Time
The physics were brutal. Usually, a hurricane moves fast. Sandy didn't. It slammed into a block of high pressure over Greenland and got "kinked" back toward the coast.
The water didn't just come from the ocean. It came from the East River. It came from the Hudson. It pushed up through the sewers. This is why the question of when did Hurricane Sandy hit New York City is more about the surge than the wind. While the winds were sustained at about 80 mph—barely Category 1 strength—the water was a different beast entirely. It rose so fast that people in the Lower East Side reported water coming up through their floorboards before they even realized the streets were flooded.
The Human Cost and the "Zones"
We talk a lot about the infrastructure, but the human toll was staggering. Forty-four New Yorkers lost their lives. That’s a number that doesn't get easier to hear with time. Most of those deaths were drownings, and many happened in Staten Island.
Staten Island got crushed.
While Manhattan was worrying about the stock exchange being closed for two days (the first time weather did that since 1888), people in Midland Beach were climbing onto their roofs. There’s a specific kind of trauma in realizing the place you feel safest—your home—is actually a trap. The city had "Evacuation Zones," and a lot of people in Zone A stayed put. Why? Because the "Boy Who Cried Wolf" effect from Irene was real.

The recovery took years. Kinda still happening in some spots, if you look closely at the "Build It Back" signs or the massive construction projects along the FDR Drive. The city realized that its 520 miles of coastline were basically undefended.
The Transit Nightmare
If you think your morning commute is bad now, imagine the week after October 29.
The subway system took a hit that experts called the worst disaster in its 108-year history. Seven subway tunnels under the rivers flooded. Salt water is poison to electrical systems. It eats away at copper wiring and relays. The South Ferry station—which had just been renovated at a cost of $530 million—was filled with water from floor to ceiling. It looked like an aquarium. It took years and hundreds of millions more to fix it.
Even today, when you're on the L train or the F, you're seeing the results of the "post-Sandy" repairs. The "L Project" that shut down nights and weekends? That was all about fixing the damage Sandy did to the Canarsie Tunnel. It’s a long-tail disaster. The event might have happened in 2012, but the city is still paying the bill.

Rebuilding for a New Reality
When we look back at when did Hurricane Sandy hit New York City, we have to look at the "Big U." This is the massive coastal resiliency project designed to wrap around Lower Manhattan. It’s a series of berms, walls, and gates. It's meant to ensure that next time a "100-year storm" happens (which, let's be real, is happening every 10 years now), the lights stay on.
There’s a lot of debate about this. Some residents in the East Village hate that the city razed East River Park to build these levees. It’s a trade-off. You lose a park to save a neighborhood. Is it worth it? Most people say yes until they see the bulldozers. But the alternative—doing nothing—is basically admitting that Lower Manhattan will eventually become an underwater museum.
The city also changed the building codes. You’ll notice in places like the Seaport or Long Island City, new buildings have their mechanical systems—generators, boilers, electrical panels—on the second floor or the roof. Gone are the days of putting the "brains" of a building in the basement. That's a direct lesson from the night of October 29.
What You Should Do Now
Living in New York means living with the water. You can't ignore it. If you're living in a coastal area, or even if you're just near a flood zone, there are a few things that aren't just "nice to have," they’re essential.
- Check the Revised Flood Maps. FEMA updated these after Sandy. You might be in a high-risk zone now even if you weren't in 2012. This affects your insurance and your evacuation plans.
- The "Go-Bag" isn't a cliché. It sounds like something for doomsday preppers, but having your documents, some cash, and your meds in one waterproof bag by the door is just common sense in a post-Sandy NYC.
- Flood Insurance. If you own a home, regular homeowners insurance almost never covers rising water. You need a separate flood policy.
- Know your zone. New York City has a "Know Your Zone" website. Use it. If the Mayor calls for an evacuation of Zone A, don't wait to see if the street starts to flood. By then, it’s usually too late to get out safely.
The reality is that when did Hurricane Sandy hit New York City isn't just a trivia question about October 29, 2012. It’s a marker for the "New Normal." The city is stronger now, sure. We have better gates, better maps, and a better understanding of how the ocean works. But the ocean doesn't care about our plans. It only cares about the path of least resistance.
Keep your batteries charged and your boots ready. The next one is a matter of "when," not "if." Residents should proactively visit the NYC NYC Hazards portal to stay updated on real-time emergency notifications and long-term coastal protection projects in their specific boroughs. Identifying your specific evacuation zone through the city's official "Find Your Zone" tool is the most immediate step any New Yorker can take to ensure they aren't caught off guard when the next surge hits.
