Living on the "Palisades" isn't just about that killer view of the Manhattan skyline. If you've spent more than a week in Union City, you know the atmosphere here is basically its own character in the story of the town. One minute you're walking down Bergenline Avenue in a light sweater, and the next, a wind tunnel effect off the Hudson River makes you feel like you're trekking through the Arctic.
Honestly, the weather in Union City NJ is a bit of a trickster. Because of our elevation on the cliffs, we catch breezes—and storms—differently than the folks down at sea level in Hoboken or over in the concrete canyons of Midtown.
The Microclimate on the Cliff
Most people check their phone apps and see the forecast for "New York City" or "Jersey City" and assume it’s the same here. It’s not. Not exactly. We sit on a giant trap rock ridge. This means when the humidity kicks in during July, the air gets heavy and sits on the town like a wet wool blanket.
Temperatures in the summer usually hover around 85°F, but the "feels like" index is the real boss. Between the lack of sprawling green space and the dense urban heat island effect, Union City can feel five degrees hotter than the suburbs in Bergen County. You'll see the locals huddled under the awnings of panaderias, waiting for that late-afternoon thunderstorm that almost always rolls through to break the heat.
The wind is the other thing. Since we are literally looking down on the river, the west winds have a clear shot at us. In the winter, that 35-degree day feels like 20 because the wind chill doesn't have any skyscrapers to slow it down before it hits your face.

Season by Season: What to Actually Expect
- Winter (December - March): It gets cold. Bitterly so. January is usually the toughest month, with lows averaging around 26°F. We get our fair share of snow, and because the streets are so narrow and the hills are so steep, a three-inch dusting can turn a commute into a nightmare.
- Spring (April - June): This is the sweet spot, though it's rainy. April brings about 3.8 inches of rain on average. Everything smells like damp concrete and blooming trees for a few weeks.
- Summer (July - August): Hot and sticky. July is the wettest month too, surprisingly, thanks to those massive tropical-feeling downpours that flood the low spots near the Lincoln Tunnel entrance.
- Fall (September - November): This is when Union City shines. The air clears up, the humidity drops, and you get those crisp, blue-sky days where the Empire State Building looks like you could reach out and touch it.
Why the Rain Hits Differently Here
You ever noticed how some streets in Union City turn into literal rivers during a heavy storm? That’s the topography at work. We have a lot of asphalt. When a "Nor'easter" or a remnant of a tropical storm hits the coast, the water has nowhere to go but down.
Infrastructure is always a conversation here. Old sewer systems meet high-density living. If the forecast calls for more than an inch of rain, you've gotta be careful about where you park. The "dip" areas can swamp a car faster than you can say "alternate side parking."
Also, fog. Because of the temperature difference between the Hudson River water and the air on the cliffs, Union City gets some of the most dramatic "soupy" fog in the metro area. There are mornings where the city across the water just... disappears. It’s eerie and beautiful, but it's a mess for the ferries and the bus drivers.
The Commuter's Weather Survival Guide
If you're one of the thousands of people heading into the Port Authority every morning, the weather in Union City NJ is your primary antagonist. A little bit of ice on the 495 approach can add an hour to a ten-minute bus ride.

- The Wind-Proof Umbrella is a Myth: Don't bother with the cheap ones from the corner store. The wind off the Palisades will snap them in thirty seconds. Get a heavy-duty one or, better yet, a real raincoat with a hood.
- Layering is the Only Way: You might be freezing while waiting for the 159 bus on 31st Street, but by the time you're crammed into a bus with 50 other people, it’s 80 degrees. Wear layers you can peel off.
- Footwear Matters: This is a walking town. In the winter, the salt on the sidewalks will eat your leather boots. In the summer, the heat from the pavement will melt thin soles. Invest in some rugged sneakers or treated boots.
Real Talk on "Best Time to Visit"
If you're bringing friends into town or planning an outdoor event at Washington Park, aim for late September. The hurricane season is usually winding down, the "swamp air" of August is gone, and the temperatures sit in a comfortable 68°F to 74°F range.
Early June is a runner-up, but the pollen counts on the ridge can be brutal if you have allergies. The trees along Manhattan Avenue are gorgeous, but they will make your eyes itch like crazy.
Dealing with the Extremes
We’ve had some wild years lately. 2025 saw some record-breaking cold snaps in December that dropped the mercury to nearly 10°F. Then you have the occasional freak heatwave where we hit triple digits.
The city usually opens cooling centers in places like the public library or certain school gyms when the heat gets dangerous. If you don't have AC, don't try to "tough it out." The brick buildings in Union City hold heat long after the sun goes down, meaning your apartment might stay hot well into the night.

How to Prepare Right Now
Check the local barometric pressure if you're prone to headaches; the rapid changes in coastal weather can be a real trigger for people living on the ridge. Keep a "go-bag" in your car or by the door with an extra pair of socks and a portable charger. Power outages aren't super common, but when a summer transformer blows because everyone has their AC on "Arctic" mode, you’ll want your phone charged.
Keep an eye on the NJ Transit alerts more than the actual weather app. Often, the "weather" that matters most is whatever is happening at the mouth of the Lincoln Tunnel. If there's a flood or a snowbank there, it doesn't matter how sunny it is in the rest of the town—you aren't going anywhere.
Monitor the tide charts for the Hudson if you live near the lower borders of town. While Union City is mostly high up, the drainage to the surrounding areas like Hoboken can back up during high-tide storm surges, effectively trapping the city on its own little island of rock. Stay ahead of the shifts by using local-specific stations rather than national feeds.
Next Steps for Staying Safe:
- Check the wind chill specifically, not just the base temperature, before heading to the bus stop.
- Sign up for Union City emergency alerts via the city's official website to get street-clearing and snow-emergency info sent to your phone.
- Invest in a high-quality dehumidifier if you live in a garden-level or older brick apartment to combat the intense summer moisture.
