You think you know the weather in Levittown NY. Most people assume it’s just "typical New York." Cold in the winter, hot in the summer, maybe some rain in between. But if you actually live here or you’re planning a move to this iconic slice of Nassau County, you know that’s basically a surface-level guess. Levittown has this weird, micro-climate vibe because of where it sits on Long Island. It’s not quite the North Shore, and it’s not quite the South Shore. It’s stuck in the middle, and that changes everything.
Honestly, the "average" stats you see on the news don't tell the whole story. You’ve probably looked at a chart and seen that January is the coldest month. Big surprise, right? But what those charts don’t show is the way the wind whips down the straight residential blocks when a Nor'easter hits. Or how the humidity in August feels like you're walking through a warm, damp sponge because the ocean breeze from Jones Beach decides to stall out five miles south of Hempstead Turnpike.
The Seasonal Reality You Won't Find on a Map
Weather in Levittown NY is a game of extremes that most people underestimate. Take the winter. January usually hovers around an average high of 39°F, with lows dipping to 26°F. That sounds manageable. But then you get a year like 2022 where a blizzard dumps two feet of snow, and suddenly, the "average" doesn't mean much when you're digging out a driveway that’s been plowed in for the third time.
The wind is the real killer here. Because Levittown was built on former potato fields, it’s remarkably flat. There are no hills to break the gust. In January, the wind speed averages about 13 mph, but during a storm, those gusts can easily top 40 or 50 mph. It turns a "cold day" into a "don't-even-think-about-going-outside" day.

Summer: The Humidity Trap
Then there’s July. The data says the average high is 82°F. That sounds like a dream. In reality? It’s often 90°F with 70% humidity. Because Levittown is densely packed with houses and asphalt, it creates a mini heat island. You’ll notice it when you drive in from the South Shore; the temperature can actually jump two or three degrees the second you cross into the 11756 zip code.
- Hottest Month: July (Avg High 82°F, but often feels like 95°F)
- Coldest Month: January (Avg Low 26°F)
- Wettest Month: July (4.83 inches of rain, mostly from crazy thunderstorms)
- Windiest Month: January (13-17 mph average)
Rain is another weird one. You’d think spring would be the wettest, but July actually takes the crown for precipitation. It’s not usually a long, dreary drizzle, though. It’s those massive, late-afternoon thunderstorms that roll in after a humid day. They dump two inches of water in an hour, flood the local sumps, and then disappear, leaving the air even stickier than before.
Why the Atlantic Ocean Is Your Best Friend (And Worst Enemy)
Living in Levittown means being perpetually influenced by the Atlantic. Even though the town isn't on the water, it’s close enough that the ocean dictates the daily rhythm. In the spring, you might have a beautiful 65°F day, but then the wind shifts to the south. Suddenly, a "sea breeze" kicks in, and the temperature drops 10 degrees in twenty minutes. It’s why everyone in Levittown keeps a hoodie in their car until at least June.
But the ocean also brings the big stuff. We’re talking about Tropical Storms and Hurricanes. Superstorm Sandy in 2012 is still the benchmark for "bad" around here. While Levittown didn't see the catastrophic storm surge that hit places like Freeport or Long Beach, the wind and rain were relentless. We lost trees that had been standing since the 1950s. More recently, the remnants of Hurricane Ida in 2021 proved that inland flooding is a real risk. When you get 7+ inches of rain in a few hours, the ground just gives up.
The Nor'easter Factor
If you aren't from the Northeast, you might not get the difference between a snowstorm and a Nor'easter. A Nor'easter is a different beast. It’s a low-pressure system that crawls up the coast, pulling in moisture from the Atlantic and cold air from Canada. For weather in Levittown NY, this often means a messy mix. You’ll start with snow, transition to sleet, move to freezing rain, and end with a slushy disaster.
The "Sleet Line" is a local legend. Meteorologists on Channel 12 will spend hours debating exactly where the rain/snow line will fall. Half the time, Levittown is right on that line. You might have friends in Hicksville getting 6 inches of powder while someone three miles south in Wantagh is getting rained on. It’s frustrating, unpredictable, and totally Long Island.
Planning Your Life Around the Forecast
So, when is it actually nice? If you want the "sweet spot," look at September and October. This is when the weather in Levittown NY finally calms down. The humidity of August breaks, the hurricane risk starts to fade, and the temperatures settle into a crisp 60°F to 70°F range.

Honestly, September is the best kept secret. The sky is clear about 63% of the time—the highest for the whole year. It’s perfect for the Levittown Carnival or just walking the neighborhood without breaking a sweat.
- Spring (March–May): Muddy and unpredictable. You'll see snow in March and 80 degrees in May.
- Summer (June–August): Humid. Keep the AC on and watch out for those 4 PM thunderstorms.
- Fall (September–November): Perfection. Crisp air, clear skies, and great for outdoor projects.
- Winter (December–February): Grey and windy. The "January Thaw" is real, but it’s usually followed by a deep freeze.
Actionable Tips for Navigating Levittown Weather
If you’re new to the area or just trying to better prep for the coming season, here’s how to handle it like a local.
First, don't trust the temperature on your phone's home screen. Check the "RealFeel" or "Heat Index." In the summer, the humidity makes an 85-degree day feel like 98. In the winter, the wind chill can turn a 30-degree afternoon into something that feels like 10.

Second, prep your home for the wind. Because the lots in Levittown are generally open, your patio furniture will end up in your neighbor's yard if you don't secure it. This is especially true during the transition seasons of late fall and early spring.
Third, understand the drainage. Levittown has a lot of "sumps"—those big fenced-in basins you see everywhere. They are there for a reason. If a heavy rain is in the forecast, make sure your gutters are clear. The soil here is somewhat sandy, which helps with drainage, but it can’t handle the volume of a tropical remnant without help.
Finally, embrace the layers. You’ll've heard this a million times, but it’s the only way to survive a Long Island spring. You might leave for work in a winter coat and come home in a t-shirt. That’s just the reality of the weather in Levittown NY.
To get ahead of the next big shift, start checking the National Weather Service's "hourly" forecast rather than just the daily high and low. It gives you a much better sense of when those wind shifts or rain bands are actually going to hit your street.
