If you’ve lived in Rockland County for even a single season, you know that the weather in Nanuet NY is less of a background detail and more of a main character in your daily life. One day you’re grabbing a light jacket for a walk at Lake Nanuet, and the next, you’re digging out the heavy-duty snow shovel because a Nor'easter decided to camp out over the Hudson Valley. It’s fickle. It’s dramatic. Honestly, it’s exactly what you’d expect from a suburb sitting right in that transition zone between the city’s coastal influence and the colder breath of the Catskills.
Most people think of Nanuet as just another stop on the New York State Thruway, but its local climate has its own weird quirks. Because we’re tucked into a pocket of Rockland, we often miss the worst of the coastal flooding that hits places like Piermont, yet we get significantly more "sticking" snow than our neighbors just ten miles south in Jersey. It’s a delicate balance of humidity, elevation, and luck.

Why the seasons in Nanuet feel so different
Nanuet falls into a humid continental climate zone. Basically, this means we get the full four-season experience, no shortcuts. Summers are a sticky, 85°F blur of humidity, while winters can drop a respectable 34 inches of snow on your driveway annually.
The humidity factor
Summer isn't just hot here; it's heavy. In July, the dew points often climb high enough to make a simple trip to the Shops at Nanuet feel like a trek through a rainforest. The average high sits around 83°F to 85°F, but with the humidity, the "real feel" frequently pushes into the 90s.
Is it unbearable? Usually not. But you'll definitely want the AC cranking by mid-afternoon. Interestingly, August is often our wettest month, averaging about 5 inches of rain. These aren't usually all-day drizzles either. We’re talking about those massive, late-afternoon thunderstorms that roll in, dump two inches of water in an hour, and then disappear, leaving everything smelling like wet asphalt and cut grass.
The long transition of autumn
September is, hands down, the best month in Nanuet. The sky clears up—statistically, it’s our clearest month—and the humidity finally breaks its grip. You’ve got highs in the mid-70s and crisp nights that drop into the 50s. It’s perfect.
By October, the foliage in nearby Bear Mountain and Harriman State Park starts to peak, and Nanuet gets that classic "Upstate" vibe despite being so close to the city. But don't get too comfortable. By late November, the "windiest" season starts to pick up, and those 10-15 mph gusts start biting.
Surviving the Nanuet winter
Winter in Nanuet officially kicks off in December, but the real teeth of the season show up in January and February. January is the coldest, with average lows hovering around 23°F. If you’re commuting into the city or over to Westchester, this is when the Tappan Zee—pardon me, the Mario Cuomo Bridge—becomes a wind tunnel.
Snowfall expectations:
- Annual Average: ~34 inches.
- Peak Month: February (averages about 10.3 inches).
- First Snow: Usually mid-to-late December.
- Last Gasps: Don't be surprised by a "tax day" flurry in mid-April.
The "slush factor" is real. Because Nanuet sits at a slightly higher elevation than the coastal parts of NYC, we often see "snow-to-rain" transitions. You might wake up to six inches of powder, but by noon, it’s turned into a heavy, grey slush that weighs a ton. It’s the kind of snow that breaks plastic shovels. Pro tip: if you see a storm coming that looks like a "mix," clear your driveway early before the rain turns the snow into concrete.
Spring: The season of mud and surprises
Spring in Nanuet is a bit of a tease. March is technically spring, but it usually acts like Winter's angry younger brother. You’ll get 50°F days followed by a sudden freeze that kills your early-blooming crocuses.
May is when things finally stabilize, though it’s actually one of the cloudiest months. We trade the snow for a lot of grey, overcast days and a 39% chance of rain on any given day. But once the trees leaf out, the suburban landscape of Nanuet completely transforms. Everything turns a deep, vibrant green, and the local parks like Germonds start filling up with families again.
What most people get wrong about our weather
A common misconception is that Nanuet weather is identical to New York City weather. It’s not. We are consistently 3-5 degrees cooler than Central Park. That might not sound like much, but in the winter, those few degrees are the difference between a cold rain in Manhattan and a treacherous ice storm in Rockland.
We also deal with "microclimates." If you’re living near the swampier lowlands toward West Nyack, you might see fog that doesn't exist up on the hills near New City. It's localized, it's weird, and it makes checking the "generic" NY forecast almost useless for Nanuet residents.

Real-world prep for Nanuet residents
Living here means being a bit of a weather nerd by necessity. If you’re moving to the area or just visiting, there are a few non-negotiables.
Invest in a good drainage system. Since Nanuet gets about 50 inches of precipitation a year—well above the US average—basement flooding is a common topic of conversation at local hardware stores. Make sure your gutters are clear before the November rains hit.
Keep an "emergency kit" in the car. During the winter months, the wind chill in Nanuet can dip into the teens or even the single digits. If you get stuck on the Palisades or Route 59 during a sudden squall, you’ll want more than just a light sweater. A real blanket, a small shovel, and some salt can save your afternoon.
Monitor the "feels like" temp, not just the number. In the summer, a 75°F day with 80% humidity feels worse than an 85°F day with 20% humidity. Conversely, in the winter, a 35°F day with those 15 mph winds coming off the Hudson feels like 20°F. Always check the wind chill and dew point before you head out.

Your Nanuet Weather Action Plan
- Winterize by November 15: Get the snowblower serviced and buy your salt early. Once the first flake falls, the Nanuet Home Depot will be a madhouse.
- Spring Planting: Wait until after Mother’s Day. Frost is a persistent threat in Rockland County until mid-May, no matter how nice that one Tuesday in April felt.
- Summer Storms: Keep an eye on the radar during July and August afternoons. Our storms move fast and can drop a lot of water in a very short window, leading to flash flooding on local roads like Convent Road.
- Commuter Check: If you cross the bridge for work, follow the "Nanuet" specific forecast on apps like WeatherSpark or local NY news, rather than just "New York, NY," to account for the Rockland temperature gap.
The weather in Nanuet NY is varied and occasionally frustrating, but it’s part of the charm of the Hudson Valley. You get the crisp falls, the white Christmases (usually), and the lush, green summers that make this corner of the world feel like home.
To get ahead of the next seasonal shift, start by inspecting your home’s exterior seals and grading this weekend to ensure the 50 inches of annual rain stays exactly where it belongs—outside.
