So, if you’ve spent any time at the Cherry Hill Mall during the dog days of August, you already know the vibe. It’s thick. It’s that heavy, South Jersey air that feels like you’re trying to breathe through a damp wool sweater. Honestly, the temperature in cherry hill isn't just a number on your iPhone—it’s a whole personality.
One day you're scraping ice off your windshield at 6:00 AM near Haddonfield Road, and by the next Tuesday, it’s 65 degrees and people are wearing shorts at Wegmans. It’s chaotic. But there’s a science to why this specific slice of Camden County feels the way it does.
The Numbers Nobody Actually Memorizes
Let’s get the basics out of the way. July is usually the month that tries to kill your AC unit. We're talking average highs around 86°F or 87°F, but that’s a bit of a lie because the humidity makes it feel more like 95°F.
On the flip side, January is the "stay inside and order PrimoHoagies" month. Average lows dip to about 26°F or 27°F. If you’re lucky, you get that crisp, dry winter air. If you’re unlucky, you get that slushy, 33-degree rain that ruins everyone's commute on Route 70.
Records? Yeah, we've had some.
The state has seen some wild Julys lately. Back in 2020, New Jersey had its hottest month on record with a statewide average of 78.8°F. That doesn't sound high until you realize that includes the middle of the night.
What’s Really Happening in the Summer?
It’s the "Bermuda High." Basically, this giant pressure system pumps tropical air straight up the coast and parks it right over our suburban sprawl. Because Cherry Hill is tucked away from the actual ocean—you've got to drive at least an hour to hit AC or Brigantine—we don't get that "sea breeze" relief.
We just bake.

The asphalt at the Garden State Pavilion or the Crowne Plaza parking lot acts like a giant radiator. Scientists call this the Urban Heat Island effect. Even though we have plenty of trees in neighborhoods like Barclay Farm, all that pavement holds onto the heat long after the sun goes down.
- July Average High: 88°F (but feels like a sauna)
- August: Often stickier, though technically a degree cooler at 86°F.
- September: The "Fake Fall" where it's 80°F until the last week.
Winter is a Different Beast
Cherry Hill is in this weird transition zone. We’re far enough north to get hit by Nor'easters, but far enough south that half the time the "blizzard" turns into a giant ice skating rink.
January is officially the coldest.
Average highs hover around 41°F.
But you've probably noticed that "very cold" is rare. It rarely drops below 13°F. It’s just... gray.
The wind is what gets you. Especially near the open spaces of Cooper River Park, the wind chill can make a 35-degree day feel like 20 real fast. March is actually the windiest month in town, averaging about 17 mph, which is why your recycling bins always end up three houses down during early spring.

The Spring and Fall Sweet Spots
If you want the best temperature in cherry hill, you aim for May or October.
May is basically perfect. Highs in the mid-70s. Everything is blooming.
October is the local favorite for a reason. Highs around 66°F and lows near 50°F. It’s perfect "hoodie weather."
Living with the Cherry Hill Climate
Look, the humidity is the real villain here. In December, the relative humidity actually peaks at about 85%. That’s why the cold feels so "damp" and gets into your bones.
You've gotta prepare.
If you're new to the area, or just tired of your pipes freezing, keep an eye on those overnight lows in late January and February. When the forecast says it’s hitting that 20°F mark, leave your faucets on a tiny drip. It’s better than a $2,000 plumbing bill.
For the summer, it's all about timing. If you’re hitting the trails at Pennypacker Park, do it before 9:00 AM. After that, the dew point climbs and you’ll be drenched in sweat before you even hit the halfway mark.
Quick Weather Survival Tips for Locals
- Check your gutters in November. If they're clogged and the temperature drops, you get ice dams. That leads to water in your ceiling. Not fun.
- Reverse your ceiling fans. In the winter, make them spin clockwise to push the warm air down.
- The "Salt" Rule. If a storm is coming and the temperature is hovering at 32°F, salt your driveway before it starts. Once it turns to ice, it's game over.
- Hydrate like a pro. In July, the temperature in cherry hill combined with the humidity means you lose water way faster than you think, even if you’re just walking from the car to the Apple Store.
Dealing with the weather here is just part of the Jersey experience. It's unpredictable, occasionally miserable, but those 72-degree May afternoons make you forget all about the humid August nights and the February slush. Stay on top of the local forecasts, keep your scraper handy, and maybe invest in a really good dehumidifier for your basement.
Check your insulation before the February deep freeze hits. Old Cherry Hill homes, especially the split-levels from the 60s, are notorious for having drafty attics that let all your expensive heat escape. Swapping out your air filters every three months will also keep your HVAC from dying when it's trying to fight off a 98-degree heatwave.
