If you’re moving to Burlington or just passing through, you’ve probably heard the standard "it gets cold in the winter and hot in the summer" spiel. But honestly? That doesn't even scratch the surface. Burlington has this weird, moody climate that can go from "perfect picnic" to "where did I put my snow shovel?" in about twelve hours flat.
I’ve seen people pack for a mild spring weekend only to end up shivering in a surprise nor'easter. Or worse, thinking July will be a breeze and finding out that New Jersey humidity is basically like wearing a warm, wet blanket.
Why Weather in Burlington New Jersey is So Unpredictable
Burlington sits right on the Delaware River, and that water matters more than you’d think. It acts like a giant thermostat, but one that’s a bit glitchy. In the winter, the river can keep things just a tiny bit warmer than the inland parts of South Jersey, which often means the difference between three inches of slush and a foot of powder.
But then there's the "Atlantic Corridor" effect. We’re in this narrow strip where cold air from Canada and warm, moist air from the Gulf of Mexico like to have a wrestling match right over our heads.
The Humidity Factor
Let’s talk about the elephant in the room: the humidity. From late June through August, the weather in Burlington New Jersey isn't just about the temperature on the thermometer. You might see 88°F and think, "Oh, that’s not bad."
Wrong.

With the dew point often hovering in the 70s, it feels like 100°F. Your hair will frizz, your shirt will stick to your back, and you’ll find yourself planning your entire life around where the nearest air conditioning unit is located. July is historically the hottest month, with average highs of 86°F, but it's the 68°F nights that stay sticky and keep you from ever really cooling down.
A Season-by-Season Reality Check
Most travel guides make every season look like a postcard. Reality is a bit messier.
Winter: The Gray Months
January and February are the heavy hitters. January is officially the coldest month, with average lows of 27°F. You’ll get those piercingly blue, windy days where the air feels like it’s biting your face.
Snowfall is a total crapshoot. Some years, we get a measly 15 inches all winter. Other years? You're digging your car out of two feet of the white stuff because a nor'easter decided to stall over the coast. According to the Rutgers Climate Lab, severe winter weather is a legitimate hazard here, often bringing ice storms that are way more annoying than snow because they take out the power lines.
Spring: The Great Tease
March is the most frustrating month in Burlington. You'll get one day that’s 65°F and sunny, making you think you can plant your garden. Don't do it. A week later, you'll have a frost.

April and May are actually when the weather starts to behave. It’s arguably the best time to be outside. Everything turns neon green, the cherry blossoms pop, and the temperatures sit comfortably in the 60s and 70s. This is when the weather in Burlington New Jersey is actually as good as the brochures say.
Summer: The Long Soak
By June, the "wet" season kicks in. It’s not a constant drizzle; it’s more like sudden, violent thunderstorms that roll in around 4:00 PM. These storms are a staple of Burlington summers. They’re loud, they’re fast, and they usually drop an inch of rain in twenty minutes before disappearing and leaving the air even steamier than before.
Fall: The Real Winner
If you can choose any time to be here, make it October. September is still kinda summer-lite—pretty warm and sometimes hurricane-influenced (think back to the remnants of Ida or Isaias). But October? October is perfect. The humidity vanishes. The sky stays clear. The average high is 66°F, which is prime "light sweater" territory.
The Surprising Risks Nobody Mentions
Most people worry about snow, but the real threat in Burlington is water.
Because we’re right on the Delaware, flooding is a genuine concern during heavy rain events. It’s not just the river overflowing; it’s the flash flooding in the streets. When tropical systems move up the coast in late summer or early fall, the ground gets saturated fast.

We also get the occasional "sneaky" tornado. They aren't the massive mile-wide monsters you see in Kansas, but Burlington County has seen its fair share of smaller, destructive twisters, particularly during those intense July heatwaves.
How to Actually Prepare for Burlington’s Mood Swings
If you’re living here or visiting, "dress in layers" is a cliche for a reason.
- The "Mud Room" is essential. In the winter and spring, you’ll be tracking in salt, slush, and Jersey mud. Having a dedicated spot for boots will save your floors.
- Download a high-quality radar app. Don’t just trust the "daily forecast." In the summer, you need to see those storm cells forming over Pennsylvania before they cross the river.
- Check your gutters in the fall. With the crazy rain totals we’ve seen in recent years—sometimes exceeding 6 inches in a single month—clogged gutters are a recipe for a flooded basement.
- Acclimatize to the humidity. If you're coming from out west, give yourself a few days. Drink twice as much water as you think you need.
The weather in Burlington New Jersey isn't always easy, but it keeps things interesting. You get the full four-season experience, for better or worse. Just maybe keep an extra ice scraper in your trunk until at least mid-April. You’ve been warned.
To stay ahead of the next big shift, keep a backup power bank charged for those summer lightning strikes and make sure your tires have enough tread for the February slush—Burlington roads don't forgive bald tires when the sleet starts falling.
