10 All-Time Rainiest Days in New York City History
These are the ten all-time rainiest days in the history of New York City dating back to 1876. The rain data is from Central Park in Manhattan.
New York can have drought periods, but they never really last for very long. The are is subject to weather fronts bringing in moisture from both the west and the south. Typically, the western fronts move quickly and tend to not drop as much precipitation as the southern fronts. Storm systems from the south pick up tons of water from the Atlantic Ocean, and can dump heavy amounts of rain and snow.
I live in the New York City area and can say with reasonable certainty that all the rainiest days listed below came from weather systems moving in from the south. On August 14, 2011, we got 5.81" of rain, which is enough to make this list, from a southern front storm.
I've lived in my current home in New Jersey for the last eight years. My basement floods every time we get seven or more inches of rain over a 24 hour period. The August 14th deluge did not flood my basement, but the rain from another date on the top ten list, April 15, 2007, did flood by basement.
