A late-season Caribbean storm

Sandy formed as Tropical Depression Eighteen in the central Caribbean Sea on October 22, 2012, late in the season. It strengthened steadily into Tropical Storm Sandy that same day, then reached Category 1 hurricane status on October 24 just before crossing eastern Jamaica. Over Cuba, Sandy intensified rapidly to Category 3 with 115 mph winds — its peak — before brushing the Bahamas and tracking generally northward off the US East Coast. The track that made Sandy historic was set up by an enormous high-pressure ridge over Greenland that blocked the typical recurvature out to sea. Instead of escaping into the open Atlantic, Sandy turned sharply west-northwest on October 29 and accelerated directly toward the New Jersey coast.

Landfall and the surge

Sandy's New Jersey landfall came at approximately 7:30 p.m. EDT on October 29, 2012, with sustained winds of 80 mph and a central pressure of 945 mb — extraordinarily low for that latitude. The storm had been officially classified as post-tropical 30 minutes earlier, a technical redesignation that did not change its impacts but did affect how warning products were issued at the time. The storm surge was the principal cause of damage. At the Battery in lower Manhattan, the water level reached 13.88 feet above mean low water — the highest on record there. Subway tunnels under the East River filled with seawater, the South Ferry station was flooded to the ceiling, and the substations serving Lower Manhattan failed. In coastal New Jersey the surge destroyed entire blocks of Seaside Heights, removed the iconic Casino Pier roller coaster into the ocean, and inundated low-lying areas of Atlantic City and the Jersey Shore. Long Beach Island and Mantoloking were essentially cut in two by surge breaches.

Recovery and the rebuild

Federal disaster recovery legislation totaling approximately $50 billion was signed into law in January 2013. The New York Metropolitan Transportation Authority spent more than $7 billion repairing and hardening the New York City Subway system, including the construction of permanent floodgates at vulnerable tunnel portals and station entrances. The New Jersey Department of Environmental Protection administered a multi-billion-dollar shore protection program including beach nourishment, dune reconstruction, and the new bulkhead system along Long Beach Island. The retired name "Sandy" was permanently removed from the rotating Atlantic hurricane name list in 2013. The NHC subsequently changed its policies to allow tropical-cyclone watches and warnings to remain in effect even for systems undergoing extratropical transition — a direct lesson learned from the confusion around Sandy's late-stage redesignation.

Frequently Asked Questions

When did Hurricane Sandy hit New Jersey?

Hurricane Sandy made landfall near Brigantine, New Jersey at 7:30 p.m. EDT on October 29, 2012, with sustained winds of 80 mph. At the moment of landfall the NHC had officially designated the storm "Post-Tropical Cyclone Sandy" — it had merged with a mid-latitude trough — but the impacts were comparable to a Category 1 hurricane making landfall over the densest population center in the United States.

How big was Hurricane Sandy?

At its New Jersey landfall, Sandy's tropical-storm-force wind field extended approximately 1,150 miles in diameter — the largest Atlantic hurricane wind field ever measured. The combination of this enormous size, the storm's perpendicular approach to the New Jersey coast, and the timing of landfall near astronomical high tide and a full moon drove a record storm surge into New York Harbor.

How much damage did Hurricane Sandy cause?

Sandy caused approximately $70 billion in damage in 2012 dollars (about $95 billion adjusted to 2024). The figure includes residential and commercial losses across the Mid-Atlantic, New York City subway system flooding repair, regional power-grid damage, beach and barrier-island erosion, and direct losses in New Jersey beach communities including Seaside Heights and the Atlantic City area.

Why was Hurricane Sandy so destructive?

Sandy combined three unusual factors: an unprecedented wind-field diameter that pushed water across the entire Mid-Atlantic Bight, an almost perpendicular approach into the New York–New Jersey coastline (most hurricanes track parallel to the coast), and landfall during a full-moon astronomical high tide. The resulting surge reached 13.88 feet at the Battery in New York City — the highest ever recorded — and inundated subway tunnels, the Hugh L. Carey Tunnel, and the Brooklyn-Battery Tunnel.

Was Hurricane Sandy a hurricane when it hit New York?

Sandy was officially redesignated "Post-Tropical Cyclone Sandy" by the NHC at 7:00 p.m. EDT on October 29, 2012 — 30 minutes before New Jersey landfall — because the storm had merged with a non-tropical trough and lost its warm-core structure. The 80 mph sustained winds, central pressure, and impacts were comparable to a Category 1 hurricane. The semantic shift was controversial, and the NHC has since changed its operating procedures to issue tropical-cyclone advisories even for post-tropical systems that retain hurricane impacts.
