Honestly, if you've lived in the 08034 zip code for more than a week, you know the drill. One minute you're grabbing a coffee at the Wegmans on Haddonfield Road in a light fleece, and the next, you’re sprinting through a freezing slush-storm that wasn’t even on the radar an hour ago. People look at the weather for Cherry Hill NJ 08034 and think it’s just a "standard Philadelphia suburb" forecast.
It isn't. Not really.
Because of how we sit—nestled between the Delaware River and the Pine Barrens—we get this weird micro-climate effect that messes with the standard predictions. Today is Wednesday, January 14, 2026, and if you looked out your window this morning, you saw exactly what I mean. It’s cloudy. Kinda damp. The temperature is hovering right around 46°F, but with that southwest wind kicking at 10 mph, it feels more like 40°F. Basically, it’s that raw Jersey winter gray that makes you want to stay in bed until April.
The Mid-January Shift: What’s Actually Happening
We’ve had it relatively easy so far this month. There’s been a bit of a "January Thaw" across South Jersey, with temperatures trending significantly warmer than the brutal cold snaps we saw in early 2025. But don't get too comfortable. The National Weather Service out of Mt. Holly is already signaling a shift.

Right now, we’re looking at a high of 52°F for today, which is actually quite mild for the middle of January. But the "wintry mix" threat is lurking. By tonight, the temperature is expected to drop to 38°F, and there’s a 25% chance of light rain moving in. If you’re commuting tomorrow morning, keep your eyes on the road. That rain can easily turn into a slick glaze if the ground temp drops faster than the air.
Thursday, January 15, is when the real reality check hits. We’re going from a spring-like 52°F today down to a high of only 36°F tomorrow. That’s a massive swing. The wind is going to shift to the west, gusting up to 30 mph. It’s going to be brutal.
Why the 08034 Zip Code is a Weather Weirdo
You ever notice how it can be dumping snow in Moorestown but just raining at the Cherry Hill Mall? That’s not your imagination. The "urban heat island" effect from the paving around Route 38 and Route 70 creates a little bubble of warmth.

- The River Factor: The Delaware River acts as a thermal regulator. It can keep us a few degrees warmer in the early winter, preventing snow from sticking when it’s piling up further inland.
- The Pine Barrens Influence: To our east, the sandy soil of the Pines loses heat incredibly fast. When a breeze blows from the east, it brings a dry, biting cold that feels sharper than the humidity-heavy air from the south.
- The "08034 Slope": There’s a slight elevation change as you move from the lowlands near the river up toward the higher ground near Woodcrest. It’s enough to change a rain-snow line by half a mile.
Looking Ahead: The Polar Vortex Rumors
There is a lot of chatter among meteorologists right now regarding the Polar Vortex. For the second half of January 2026, the models are looking increasingly "unsettled," which is a polite way of saying we might get hammered.
Specifically, watch the window between Saturday, January 17 and Monday, January 19. While Saturday looks partly sunny with a high of 41°F, there’s a system tracking toward the East Coast that could bring significant snow or ice. By Tuesday, January 20, we are looking at a projected high of only 27°F and a low of 17°F. That is "pipe-bursting" territory.
If you haven't checked your outdoor spigots or salt supply, do it now. Seriously.
Common Misconceptions About South Jersey Winters
Most people think January is our snowiest month. Statistically, it's often February or even early March that brings the "Big Ones." January in Cherry Hill is usually characterized more by its cloud cover—about 53% of the time the sky is overcast. It’s the gloomiest month of the year, even if it’s not always the snowiest.
Humidity is another weird one. You’d think winter would be dry, but Cherry Hill stays surprisingly humid, averaging around 83% relative humidity in January. This is why the cold here feels "wet." It gets into your bones in a way that a dry, crisp cold in the Midwest just doesn't.

Practical Steps for the Next 7 Days
Since the weather for Cherry Hill NJ 08034 is about to do a total 180-degree flip, here is how you should actually prepare:
- Wednesday (Today): Enjoy the 52°F. It’s the warmest day you’ll see for at least two weeks. Get the leaves out of your gutters before the rain/snow mix hits tonight and freezes them solid.
- Thursday Morning: Anticipate a messy commute. Even if it’s just rain, the wind gusts of 30 mph will make driving high-profile vehicles on I-295 a nightmare.
- Friday: The temperature won't break 32°F. If you have pets, keep their outdoor time short. The ground will be frozen solid by noon.
- Weekend Prep: Stock up on the basics by Friday night. If the Saturday/Sunday system shifts further west, we could see the first "plowable" snow of the season.
The most important thing to remember about 08034 weather is that the forecast is a suggestion, not a promise. Between the river, the turnpike traffic, and the Atlantic influence, things change fast. Keep your ice scraper in the car and your heavy coat by the door. You’re going to need them both by Friday.
Check your car's tire pressure today while it's still relatively mild; those pressure sensors are going to start screaming the second that arctic air hits on Thursday night.
