Honestly, Millville is a bit of a weather enigma. If you’ve spent any time at the Holly City’s airport or wandering near the Maurice River, you know the sky here doesn’t always follow the script written for Philly or Atlantic City. We're tucked just far enough inland to miss the immediate coastal warming but close enough to the Delaware Bay to get smacked by weird moisture plumes that the rest of the state completely misses.
Right now, looking at the weather for millville nj on this Thursday, January 15, 2026, it’s a classic winter standoff.
The current temperature is sitting at exactly 36°F, but the air doesn't feel that "warm." Thanks to a steady 14 mph wind coming straight out of the west, the real-feel temperature is actually a biting 27°F. It’s sunny, sure, but it’s that deceptive winter sun that offers zero warmth the moment you step out of the light. Humidity is low at 38%, which explains why the air feels so crisp—or, more accurately, why your skin probably feels like sandpaper.
The Weirdness of South Jersey Winters
South Jersey weather is basically a game of "will it or won't it" with the rain-snow line. Today, the high is expected to reach 40°F, while the low tonight will dip down to a freezing 20°F.

There is a 35% chance of snow during the daytime. That’s a frustrating number. It’s high enough to make you look for the shovel, but low enough that it might just end up being a few "social media flurries" that don't even stick to the mulch. The wind is going to stay persistent, too, holding at about 15 mph.
Historically, January is the coldest month for us. We usually average a high of 42°F and a low of 26°F. Today is actually trending slightly colder on the low end than the historical norm. If you're heading toward the water, keep in mind there's a Small Craft Advisory active for the Delaware Bay until 6 PM today, followed by a Gale Warning tonight. The west winds are kicking up gusts near 35 knots out there. Basically, stay off the boat.
Why Millville Is Its Own Climate Zone
The weather for millville nj is shaped heavily by the Pine Barrens to our north and the bay to our south.

Unlike the urban heat island of Philadelphia, Millville can experience massive temperature swings once the sun goes down. It's not uncommon for us to be five degrees colder than Vineland just because of how the air settles in the lower elevations near the river.
- Average January Snowfall: Roughly 5.1 inches.
- Cloud Cover: January is actually our cloudiest month, with overcast skies about 52% of the time.
- The Wind Factor: We get a lot of "tunneling" wind from the west that follows the flat terrain of the local farms.
When people talk about Jersey weather, they usually think of the Shore. But Millville is different. We get the "Piney" cold. It’s a damp, deep-in-your-bones cold that makes the feels-like 27°F we’re seeing today feel more like 15°F if you’re standing in the wind.
What to Actually Do With This Forecast
If you're planning your day, don't let the "sunny" label fool you. That 35% snow chance usually manifests as a quick burst of graupel or light snow that can slick up the backroads around the Motorsports Park or the outskirts of town toward Cedarville.

Layering is non-negotiable today. With the UV index at a measly 1, you aren't getting any help from the sun. The most important thing to watch is that temperature drop tonight. Going from 40°F down to 20°F means any moisture on the roads from that 35% precip chance is going to turn into a sheet of ice by 9 PM.
Seal up your drafty windows and maybe throw an extra blanket on the bed. It’s going to be a loud, windy night as that west wind hammers the siding. Tomorrow looks even colder, with a projected high of only 33°F. Winter has finally decided to show up for real.
Practical Steps for Millville Residents Today:
Check your tire pressure; these 20-degree drops usually trigger those annoying dashboard sensors. If you have outdoor pets, bring them in before 5 PM when the sun dips and the wind chill takes over. Lastly, if you’re commuting toward the bay tomorrow morning, leave ten minutes early to deal with potential black ice from the evening’s clearing skies.
