It is 2026, and if you are standing outside near the Oxford Valley Mall right now, you probably already know that the temperature in Levittown PA is more than just a number on your phone. It is a mood. It is a logistical puzzle. One day you are digging your car out of a slushy mess from a clipper storm, and three months later, you are hiding in the air conditioning because the humidity from the Delaware River has turned the air into a warm, wet blanket.
Honestly, living here means becoming an amateur meteorologist by necessity. You quickly learn that "40 degrees" in January feels wildly different when the wind is whipping off the open fields near the edge of town than it does in the middle of a sheltered cul-de-sac in Forsythia Gate.

The Reality of the Temperature in Levittown PA
Most weather apps will tell you that Levittown follows a standard humid subtropical pattern. That is the textbook answer. But the real experience is a bit more chaotic. You have probably noticed that the "average" high in January is around 40°F, but we rarely actually spend time at that average. We usually oscillate between "freezing our noses off" at 25°F and those weird, unsettling 55°F days that make the local plants think it’s spring way too early.
January is officially the coldest month. If you are checking the temperature in Levittown PA during this stretch, you are looking at night-time lows that hover around 26°F. It is that damp, bone-chilling cold that Pennsylvania is famous for. Unlike the dry cold you might find out west, the moisture here clings to you. It makes 30 degrees feel like 15.
Breaking Down the Seasons
Spring is a bit of a tease. March starts off windy—the windiest month of the year, actually—with gusts that make the 50-degree highs feel much cooler. By the time May rolls around, things get comfortable. Highs reach about 73°F. This is arguably the best time to be outside. The humidity hasn't quite ramped up yet, and the nights are still cool enough to keep your windows open without the hum of the AC.
Then comes July. If you’ve spent a summer here, you know.

The average high is 86°F, but that doesn't account for the heat index. Because Levittown is situated in the low-lying Delaware Valley, the humidity settles in and stays. It is common to see 10 to 20 days a year where the temperature breaks 90°F. When you factor in the dew point—often sitting in the mid-60s—the "real feel" easily clears 100°F.
Autumn is the local favorite for a reason. September brings highs of 77°F, dropping to a crisp 66°F in October. It’s predictable. It’s dry. It’s the one time of year when the temperature in Levittown PA actually behaves itself.
Why the "River Effect" Matters
A lot of people forget how much the Delaware River influences our local climate. Since Levittown is basically a neighbor to the water, we often experience slightly more moderate temperatures than places further inland, like Doylestown or even parts of Philadelphia.
The water acts as a thermal regulator. In the early winter, the river stays warmer than the land, which can sometimes turn a predicted snowstorm into a "slush-fest" for us while the rest of the county gets six inches of powder. Conversely, in the spring, the cold water can keep the immediate area a few degrees cooler, delaying the bloom of those famous Levittown cherry blossoms by just a few days.
- Hottest month: July (Average high of 86°F)
- Coldest month: January (Average low of 26°F)
- Wettest month: July (Nearly 5 inches of rain on average)
- Driest month: February (Usually around 2.2 inches of precipitation)
Extreme Weather and What to Watch For
We can’t talk about the temperature in Levittown PA without mentioning the extremes. Pennsylvania has seen a significant uptick in "billion-dollar weather events" over the last few decades. For us, that usually means two things: tropical remnants in the summer and "clippers" in the winter.
The state climatologist data shows that Pennsylvania is getting warmer and wetter. We are seeing about 1.8°F of warming over the last century, which doesn't sound like much until you realize it means more frequent heatwaves. By mid-century, we might see 30+ days a year where the temperature hits 95°F. That is a massive shift for a town built on 1950s infrastructure.

Flooding is the other big concern. When heavy rain hits the frozen ground in late winter, or when a summer thunderstorm dumps three inches of rain in an hour, the local drainage systems get tested. Places near Queen Anne Creek or the various man-made lakes in the area have to stay vigilant.
Surviving the Levittown Climate
If you are new to the area or just trying to manage your utility bills, there are a few local "rules" to live by.
First, don't trust a sunny February morning. If the temperature in Levittown PA looks nice at 8:00 AM, there is a 50% chance a cold front will have you shivering by noon. Layers are your best friend.
Second, handle your insulation. These houses—many of which are the original Levitt & Sons models—weren't always built with 2026 energy efficiency in mind. If you haven't checked your attic insulation or replaced those old single-pane windows, your HVAC system is going to fight a losing battle against the Bucks County humidity.
Third, watch the dew point. In the summer, the temperature is only half the story. If the dew point is over 65, you are going to feel miserable regardless of what the thermometer says. That’s the time to plan indoor activities or head to the pool.
Practical Next Steps for Locals
Since the weather here is getting more unpredictable, it pays to be prepared. Check your home's grading before the spring rains start to ensure water is moving away from your foundation. If you’re a gardener, wait until at least mid-May to plant your sensitive annuals; we’ve had "surprise" frosts as late as Mother's Day that can ruin a weekend's worth of work at the nursery.
Keep an eye on the local NWS Philadelphia/Mount Holly briefings rather than just relying on a generic national app. They understand the specific geography of the Delaware Valley and provide much more accurate "real feel" data for our specific corner of Bucks County.
