You've probably checked your phone, seen a 40% chance of rain, and figured you’re safe to wash the car or head out to Freedom Park. In Medford, that’s usually your first mistake. Weather here doesn’t always follow the broad Philadelphia-area "box" that big-box weather apps love to use. Because we sit right on the edge of the Pine Barrens, our medford nj weather hourly data often tells a much quirkier story than the rest of Burlington County.
Today, January 15, 2026, is a perfect example of that Medford "mood swing." We started the morning with some lingering clouds and a touch of humidity at 81%, but the atmosphere is currently shifting fast. If you’re looking at the hourly breakdown for the rest of the day, you’ll see temperatures peaking around 38°F before they absolutely crater tonight.
It's cold. Honestly, it’s the kind of cold that bites because of the wind. We’re looking at west winds sustained at 16 mph, which basically means that "38 degrees" is a lie—it’s going to feel like the high 20s most of the afternoon.
Why the Hourly Forecast in Medford is Different
Most people don't realize that Medford exists in a bit of a geographic transition zone. To the west, you have the urban heat island effect of Philly and Cherry Hill. To the east, the vast, sandy expanse of the Pine Barrens begins. This matters for your medford nj weather hourly planning because sand loses heat way faster than pavement or loamy soil.
Have you ever noticed that Medford can be three or four degrees colder than Marlton at 11:00 PM? That’s not a glitch in your car’s thermometer. It’s the "radiational cooling" hitting the sandy soil.

- Morning (6 AM - 10 AM): Often damp. We see a lot of "Pine Barrens fog" when the humidity is high like it was this morning.
- Midday (11 AM - 3 PM): This is usually your window of stability. Today, the sun is fighting through, but those 25 mph gusts are going to keep you in a heavy coat.
- Evening (4 PM - 8 PM): The drop-off. Once the sun dips (sunset is around 5:00 PM this time of year), the temperature doesn't just slide; it dives.
The Hourly Breakdown for January 15, 2026
If you’re planning your evening commute or a late-night run to Murphy’s Oxbow, here is what the atmosphere is actually doing. We are transitioning from a "cloudy with a chance of flurries" morning into a "clear but freezing" night.
12:00 PM - 2:00 PM: Temperatures hovering at 38°F. The sky is clearing, but the wind is the main character here. Expect gusts that make walking the dog at Kirby’s Mill a bit of a chore.
3:00 PM - 5:00 PM: The sun stays out, but the "real feel" drops into the low 20s. This is when the southwest wind flips more toward the west-northwest, bringing in that drier, Canadian air.
6:00 PM onwards: Total loss of heat. We are heading toward a low of 20°F by early tomorrow morning. If you have sensitive plants in a sunroom or haven't disconnected your hoses, this is the hour the frost starts to take hold.

What the "Chance of Precipitation" Actually Means Here
We’ve all seen the "30% chance of snow" and wondered if we should buy bread and milk. In Medford, the medford nj weather hourly precipitation percentage is often about "virga"—rain or snow that evaporates before it hits the ground—or highly localized squalls.
Because we are flat and relatively close to the Delaware Bay, we sometimes get "ocean moisture" that creeps in and meets cold air coming from the north. This creates those weird micro-events where it’s snowing on Tuckerton Road but just cloudy on Main Street.
- Humidity Spikes: Our average humidity in January is a whopping 83%. This makes the cold feel "wet" and bone-chilling compared to the dry cold out west.
- Wind Chill: With an average winter wind speed of 15.7 mph, the hourly forecast's "Ambient Temperature" is almost irrelevant. Always look at the "Feels Like" column.
- The Pine Barrens Effect: The porous sandy soil means that after a heavy rain, the humidity can stay trapped in the low-lying areas (like the Lakes) long after the sun comes out.
Navigating the Seasons in 08055
While we’re focused on the current freeze, it’s worth noting how the hourly trends shift as we move toward the "Comfortable Weather" months. Experts at the Rutgers State Climatology Lab often point out that South Jersey has some of the most variable daily weather in the country.
In the spring, Medford is famous for "false starts." You’ll get an hourly forecast showing 70°F at 2:00 PM in late March, only to see it drop to 35°F by 8:00 PM. This "diurnal temperature swing" is much more dramatic here than in coastal towns like Ocean City because we don't have the ocean to act as a heat stabilizer in the spring.

In the summer (especially July), the hourly humidity is the killer. We often hit "uncomfortable" levels by 10:00 AM. If you’re planning to hike at Wharton State Forest or bike the local trails, the hourly data usually suggests a "hard stop" by 11:00 AM to avoid the heat index peak, which can easily hit 100°F even if the thermometer says 90°F.
Practical Tips for Tracking Medford Weather
Stop relying on the "built-in" app on your iPhone that just says "Philadelphia." It’s often wrong for us.
Instead, look for stations specifically at the South Jersey Regional Airport (KVAY) or the local Mount Holly (KTPD) station. These are much closer to Medford's actual elevation (about 52 feet above sea level) and soil profile.
If you are a local gardener or someone who works outdoors, keep an eye on the dew point in the hourly forecast. When the dew point and the temperature get within 2 or 3 degrees of each other, expect fog or black ice on the back roads like Medford Lakes Road or Branin Road.
Your Medford Weather Action Plan
Don't let the "sunny" icons fool you today. The air is dry, the wind is high, and the temperature is on a downward escalator.
- Layering is non-negotiable: Between 2:00 PM and 6:00 PM today, you’ll lose about 10 degrees of actual heat, but the wind chill will make it feel like a 20-degree drop.
- Watch the wind: Secure any loose outdoor decor or trash cans. Gusts up to 25 mph are expected through the early evening.
- Prepare for the freeze: Tomorrow morning will start at a brutal 20°F. If you’re commuting, give your car a few extra minutes to warm up—the humidity from this morning's clouds will likely have turned into a thin layer of frost on windshields.
Check the hourly updates again around 5:00 PM. That’s when the "cold front" fully settles in, and you’ll know exactly how many layers you’ll need for the Friday morning hustle. Keep an eye on local sensors for the most accurate, street-level data.
