If you’re planning to hit the boards or grab a seat at a poker table this week, you better pack a parka. And maybe a raincoat. Honestly, probably both. Atlantic City is about to get hit with that classic, messy "Jersey Shore transition" weather that makes packing a total nightmare.
Right now, it’s a crisp 39°F outside. It feels more like 30°F thanks to a 14 mph southwest wind whipping off the water. If you're out near the Steel Pier tonight, you’ve noticed the sky is clear but starting to get those periodic "checkerboard" clouds moving in.
The big story isn't just the cold, though. It's the weird mix of rain and snow we're looking at for the next 7 days.
The Atlantic City 7 Day Forecast Breakdown
Look, Atlantic City weather is basically a game of "how close is the rain-snow line?" This week, the answer is "uncomfortably close."
Saturday, January 17: We’re starting the weekend with a high of 45°F. Sounds okay, right? Wrong. There’s a 40% chance of light rain during the day. By nightfall, things get dicey. The temperature drops to 36°F, and that rain is going to mix with snow. If you're driving down the Parkway, watch for those slick spots where the rain turns to slush.
Sunday, January 18: This is the messiest day of the bunch. We’re looking at a high of only 36°F with a continued 40% chance of a rain and snow mix. It’s that heavy, wet Atlantic City slush that ruins shoes. The wind shifts to the north at 7 mph, and the humidity is going to be a swampy 88%. Expect damp, bone-chilling cold that sticks to you.
Monday, January 19: Finally, some sun. It’ll be 37°F and sunny, but the night gets brutal. We’re talking a low of 20°F. If you’re heading to the casinos, valet your car. You don’t want to be walking through a parking garage in 20-degree weather at 2 AM.
Mid-Week Reality Check
By Tuesday, the "sunny" part of the forecast is a bit of a trap.

It’s going to be the coldest day of the week. We are looking at a high of 24°F and a low of 18°F. Even with the sun out, that 16 mph northwest wind is going to make it feel like single digits.
Wednesday, January 21, bounces back a little to 38°F with some clouds, but by Thursday, we are right back into the "rain and snow" cycle. High of 41°F, low of 29°F, and a 35% chance of snow showers at night.
Basically, the 7 day forecast for Atlantic City New Jersey is a seesaw. You’re going from 45 degrees one day to 24 degrees three days later.
Why the Ocean Changes Everything
People forget that the Atlantic Ocean is a massive radiator.
Right now, the water temperature at the Absecon Channel is sitting around 40.5°F. That’s actually warmer than the air most days this week! This is why you’ll see it snowing in Egg Harbor Township while it's just raining on the Boardwalk. That five-mile difference between the mainland and the island is everything.
If the wind is coming off the ocean (onshore), it brings that "warm" 40-degree air and keeps the snow away. But this week, we’ve got a lot of southwest and northwest winds. Those are land winds. They bring the cold air from the continent out to the coast, which is why we’re seeing those 18-degree lows.

How to Handle This Week in AC
If you’re coming down, don't just look at the high temperatures. The "feels like" is what matters.
- Footwear is key. Sunday’s rain-snow mix means the streets will be a puddle of gray slush. Wear waterproof boots, not your "going out" sneakers.
- The Wind Tunnel Effect. The gaps between the massive casino towers turn a 15 mph wind into a 30 mph gust. If it says it's 24 degrees, treat it like it's 10.
- Layering. Since you'll likely be moving from 72-degree casino floors to 30-degree boardwalk air, you need stuff you can peel off quickly.
Honestly, it’s a typical January at the shore. Wild swings, a bit of slush, and enough wind to make you question why you left the house. But hey, at least the casinos are climate-controlled.
Check the forecast one last time before you leave, especially for Sunday. That rain-snow line is notorious for shifting 10 miles at the last second, which is the difference between a car wash and a snow shovel.
Stay warm out there. Avoid the boardwalk when the wind is gusting over 20 mph unless you really like the "exfoliating" feeling of salt air and ice on your face.
Next steps for your trip: Grab some heavy-duty wool socks and check the tide charts if you're parking in low-lying areas, as that Sunday mix combined with a north wind can sometimes push extra water into the back bays.
