Winter at the Shore is weird. Honestly, if you’re looking at the atlantic city extended weather forecast and expecting a simple "cold and snowy" or "mild and rainy" answer, you’re probably going to be disappointed. Or surprised. Atlantic City has this strange microclimate where the ocean acts like a massive space heater—or a giant ice pack—depending on which way the wind is blowing.
Right now, we're looking at a classic mid-January squeeze. Today, Sunday, January 18, 2026, the city is dealing with a messy mix of rain and snow. It’s sitting at 34°F, but with the northwest wind kicking at 14 mph, it feels like a biting 24°F. That’s the "Boardwalk chill" locals know all too well. Humidity is thick at 89%, so that cold just sinks right into your bones.
The Immediate Outlook: Sun vs. Shivers
Tomorrow, Monday, January 19, things shift. We lose the precipitation but keep the cold. Expect a high of 37°F and a low that dips down to 21°F. It’ll be sunny, which is great for a walk, but the wind is actually picking up to 16 mph from the southwest.
Tuesday is looking like the coldest day of this stretch. We’re talking a high of only 27°F. The low? A frigid 17°F. If you’re planning on being outside, you’ve basically got to layer up like you’re heading to the Arctic.
What the Next 10 Days Look Like
| Day | Conditions | High/Low | Wind |
|---|---|---|---|
| Wednesday, Jan 21 | Partly Sunny | 38°F / 19°F | 21 mph S |
| Thursday, Jan 22 | Partly Sunny | 43°F / 27°F | 12 mph SW |
| Friday, Jan 23 | Mostly Cloudy | 33°F / 17°F | 17 mph W |
| Saturday, Jan 24 | Snow Showers (Night) | 20°F / 14°F | 15 mph NW |
| Sunday, Jan 25 | Snow Showers | 22°F / 15°F | 11 mph N |
Basically, the middle of the week sees a brief "warm-up" (if you can call 43°F warm), followed by another sharp drop over the weekend. Saturday night into Sunday has the highest potential for actual snow accumulation, with highs struggling to even break 20°F.

Why the Atlantic City Forecast Is Never Simple
Meteorologist Joe Martucci has often pointed out that the 2025-2026 winter season is being driven by a weak La Niña. This usually means a "battleground" scenario for the Mid-Atlantic. We’re stuck between the warm air from the south and the cold Canadian air masses.
In Atlantic City, the ocean temperature is currently hovering around 41°F. Because water holds heat longer than land, the "immediate coast" (the Boardwalk and the casinos) often stays 5 degrees warmer than the mainland near the airport. This is why you’ll often see rain at the Steel Pier while it’s snowing five miles inland at the Atlantic City International Airport (KACY).

The "Miller B" Factor
Most of the storms we’re seeing this month are what forecasters call Miller-B systems. These aren't the giant "Nor'easters" that dump two feet of snow in one go. Instead, they’re messy. They often start inland, transfer their energy to the coast, and result in a "redeveloping precipitation shield."
What does that mean for your weekend plans? It means the "snow/mix/rain line" is constantly moving. You might wake up to snow, see it turn to sleet by noon, and have it end as a freezing drizzle. It's annoying for drivers, but it's the reality of the atlantic city extended weather forecast this time of year.
Real-World Survival for AC in January
If you're heading down for a concert or a weekend at the tables, don't trust the "high" temperature. Humidity in AC stays high—usually around 80% in January. Cold, humid air is much harder to dress for than "dry" cold.
- Wind-Proof is Life: The wind comes off the ocean and cuts through wool coats. Wear a shell or a down jacket with a nylon exterior.
- Watch the Tides: This winter has seen more frequent "quantity over quality" tidal flooding. Even a small storm can flood the Black Horse Pike or the back-bay streets if it hits during high tide.
- Footwear Matters: The Boardwalk gets slippery. It’s wood, it’s wet, and it freezes fast. Leave the slick-bottom shoes in the hotel room.
By the end of next week, specifically Wednesday, January 28, things look to remain chilly with a high of 23°F. This isn't a "thaw" year. We are firmly in the grip of a cold cycle that looks to last at least through mid-February.

Actionable Insight: If you’re planning travel for the weekend of Jan 24-25, keep a close eye on Friday's update. The shift from "partly sunny" to "snow showers" is a 20-degree drop in high temperatures, which will likely impact bridge icing and parkway conditions. Pack an emergency kit in the car, specifically focused on de-icing tools and extra blankets, as the 14°F nighttime lows are no joke if you get stuck.
