If you’ve spent any real time in Bergen County, you know the vibe. One day you’re walking down Palisades Avenue in a light hoodie, and the next, you’re digging your car out from under a foot of heavy, wet slush. Honestly, the weather in Garfield NJ isn't just a daily forecast; it’s a lifestyle hurdle. It’s the kind of climate that keeps your basement pump on high alert and your closet perpetually confused.
Most people look at the averages and think they understand what’s coming. They see "warm summers" and "cold winters" and figure it's standard Northeast stuff. But Garfield has its own quirks, mostly thanks to its relationship with the Passaic River and its position in the valley. It’s a bit wetter, a bit more humid, and sometimes a lot more unpredictable than the "official" Newark or Teterboro readings might suggest.

The Reality of the Garfield Seasons
Let’s be real: January is brutal. It’s not just the temperature, which averages a high of 39°F but often feels like 10°F when that wind kicks up off the river. It’s the gray. January is the cloudiest month here, with the sky staying overcast or mostly cloudy about 53% of the time. You’ve basically got a 1-in-2 chance of seeing a depressing ceiling of slate-colored clouds when you step outside.
By the time we hit July, the script flips entirely. It gets thick. We’re talking an average high of 85°F, but the humidity makes it feel like you’re breathing through a warm, damp towel. July is also the wettest month on average, bringing in about 5 inches of rain. These aren't just light drizzles; they're those heavy, afternoon thunderstorms that turn the streets into temporary streams.
The Snow Situation
Everyone remembers the big ones, like the 2011 storms or the random October surprises, but the day-to-day reality is more of a grind. Garfield averages about 29 inches of snow per year.
- February is usually the king of the snow pile, averaging 9.4 inches.
- The "snowy period" stretches from early December to late March.
- You’ll rarely see anything measurable after April 1, though the NJ weather gods love to prove us wrong with a stray flurry.
If you're moving here, buy a good shovel before the first frost. By the time the flakes start falling, the local hardware stores are usually picked clean of the good ergonomic ones.
Why the Passaic River Changes Everything
You can’t talk about weather in Garfield NJ without talking about the Passaic River. The Dundee Dam area and the low-lying streets like Outwater Lane and River Drive are basically the front lines of North Jersey flooding.
The U.S. Army Corps of Engineers has been studying this basin since basically the dawn of time. They’ve noted that since 1900, the basin has seen at least 26 major floods that were bad enough to get a Federal Disaster declaration. When the NWS station at Dundee Dam (DDCN4) hits the "Action" stage at 3.5 feet, residents start watching the clouds. If it hits 7 feet? That’s major flooding territory. At 8.5 feet, Midland Avenue starts looking like a lake.
It’s a weird paradox. You want the rain for the gardens, but you dread the "nor'easters" that park themselves over the state for three days. These storms are the real villains of Garfield weather. They don’t just bring rain; they bring a slow-motion rise of the river that can trap cars and ruin basements long after the sun comes back out.

Spring and Fall: The "Comfortable" Months
There is a silver lining. Garfield gets about 150 "comfortable" days a year. These are those golden windows where the high is between 65°F and 86°F, and the dew point stays low enough that you aren't sweating through your shirt.
September is arguably the best month in the city. The sky is clear or mostly clear 63% of the time—the highest of the year. The humidity of August breaks, the leaves start to turn near 20th Century Field, and the air actually feels crisp. It’s the one time of year when the weather isn't trying to drown you or freeze you.
Survival Tips for the Garfield Climate
If you’re living here or just passing through, there are a few "pro-move" ways to handle the local elements.
Check the River Gauges, Not Just the App
Standard weather apps tell you if it’s raining. They don't tell you if the Passaic is cresting. Use the NOAA Water Prediction Service for the "Passaic River at Clifton (Dundee Dam)" to see real-time levels.
The Basement Rule
If you live in the lower parts of town, assume your basement will eventually see moisture. It’s not a matter of "if" but "when." Invest in a high-quality sump pump with a battery backup. When the power goes out during a summer storm, that battery is the only thing standing between you and a very expensive swimming pool in your cellar.

Dress in Layers (The Jersey Uniform)
In April and October, the temperature can swing 20 degrees in a single afternoon. You’ll start the day in a winter coat and end it in a T-shirt.
Watch for Ice on the Bridges
The bridges crossing over into Clifton or Paterson freeze faster than the surface roads. In those "wintry mix" scenarios that NJ loves so much, the bridge decks become skating rinks while the rest of the road is just wet.
The weather in Garfield NJ is a study in extremes. We deal with some of the coldest Januaries and the muggiest Julies in the region, all while keeping a nervous eye on a river that has a history of overstepping its bounds. But for those 150 perfect days, it’s worth the hassle. Just make sure you know where your snow boots are and keep an eye on the dam levels.
