Typical January temperature pattern in Atlanta:

Key takeaways for January temperatures in Atlanta:

• Freezing temperatures are possible, especially overnight and early morning.
• Afternoons are often cool but not brutal, making light layers comfortable.
• Warm spells happen – it’s not unusual to get a few days in the 60s or even near 70°F when a warm front moves through.
• Cold snaps do occur, with overnight lows dropping below freezing and occasional days that don’t get out of the 30s or 40s.

Rain, Clouds, and Humidity

January in Atlanta tends to be:

• Cloudy to partly cloudy much of the time
• Moderately rainy, with multiple rainy days spread throughout the month
• Damp, especially early in the morning and after rain

Common patterns:

• Light to moderate rain is more common than thunderstorms.
• Rain often comes in fronts: a day or two of rain, followed by clearer, cooler air.
• You may go several days with dreary, overcast skies, then get a stretch of crisp, sunny weather.

If you live in or visit Atlanta in January, it’s wise to:

• Keep a compact umbrella or light rain jacket handy.
• Expect wet roads and slower traffic on rainy mornings and evenings.
• Be prepared for fog in some areas, especially near rivers or low-lying spots, during cool, calm mornings.

Snow and Ice: How Likely Are They in January?

Atlanta is known for being snow-sensitive: even a little winter weather can cause big disruptions. But true snowstorms are uncommon.

How often does it snow in January?

• Light snow or flurries: Occasionally, some years may see a dusting or a brief light snow event.
• Measurable accumulation: Happens some years but not most; when it does, totals are often modest.
• Ice is often the bigger problem: Freezing rain or sleet can create icy roads and sidewalks even when snow is minimal.

What winter weather can look like in Atlanta

• A cold rain that briefly mixes with sleet or wet snow and doesn’t stick.
• A shallow layer of ice on bridges and overpasses, especially at night or early morning.
• In less common events, snow-covered streets that lead to closures and delays across the metro area.

Because Atlanta’s infrastructure and drivers aren’t geared to frequent snow and ice:

• School closures and delays are common when ice or snow is in the forecast.
• Elevated roadways (interstates, ramps, bridges) can become slick quickly.
• Public agencies may pre-treat major roads, but neighborhood streets can stay icy longer.

For official winter weather alerts affecting Atlanta and Fulton County, local residents often rely on:

• National Weather Service – Atlanta/Peachtree City Office
  4 Falcon Drive, Peachtree City, GA 30269
  Recorded forecast/phone info is often available through national weather lines.

Wind and “Feels Like” Temperatures

January winds in Atlanta are usually light to moderate, but they can make it feel colder than the actual temperature.

• Breezy days in the 40s °F can feel like the 30s °F.
• After a cold front, dry, northwesterly winds can make mornings feel especially brisk.

When planning outdoor time:

• Remember the wind chill effect—what the weather “feels like” on your skin.
• A windproof or insulated jacket helps a lot more than just a thick sweater on breezy days.

Daylight in Atlanta During January

January days are short, and that affects commutes, outdoor activities, and travel plans.

Typical daylight pattern in Atlanta during January:

• Sunrise: Around 7:30 a.m. early in the month, gradually a bit earlier by month’s end.
• Sunset: Around 5:30–6:00 p.m.

What this means in practice:

• Morning and evening commutes often happen in the dark, especially early in January.
• Outdoor errands or exercise are often best planned midday, when it’s both lighter and warmer.
• Visitors should plan sightseeing and walking tours to maximize daylight hours.

What to Wear in Atlanta in January

Layering is the key for Atlanta’s variable January weather. You want to be ready for chilly mornings, comfortable afternoons, and cool evenings.

Everyday clothing basics

Consider building outfits around:

• Light to medium-weight jacket (denim, fleece, lined windbreaker, or light parka)
• Sweaters or sweatshirts for layering
• Long-sleeve shirts or light base layers
• Jeans or long pants
• Closed-toe shoes (sneakers, waterproof shoes, or casual boots)

On colder or wetter days, you may also want:

• Heavier coat or insulated jacket when a cold snap hits
• Scarf, hat, and gloves, especially if you’ll be outside at night or early morning
• Water-resistant outer layer if rain is in the forecast
• Wool socks or thicker socks on especially chilly days

For walking around Atlanta

If you’re visiting or exploring neighborhoods like Midtown, Downtown, Old Fourth Ward, or Buckhead:

• Wear comfortable walking shoes that can handle wet sidewalks.
• Dress in layers you can easily take off if the sun comes out and temperatures climb into the 60s °F.

How January Weather Affects Daily Life in Atlanta

Commuting and traffic

January brings:

• Wet roads on many days due to rain.
• Potential black ice on bridges and overpasses on the coldest mornings, especially after overnight rain.
• Slower traffic when winter weather is in the forecast, as many Atlantans adjust driving habits.

If you’re commuting:

• Allow extra travel time during rainy or freezing mornings.
• Pay special attention to interstates like I‑285, I‑75, I‑85, and GA‑400, where traffic can back up quickly in bad weather.
• Check local forecasts and traffic reports before leaving home, especially if temperatures are near freezing.

Outdoor activities and events

Many Atlanta attractions remain open year-round, including:

• Atlanta BeltLine trails
• Piedmont Park

January is often pleasant enough for:

• Walking or jogging during the warmest part of the day
• Casual outdoor dining on heated patios
• Visiting outdoor attractions on clear, sunny days

However, weather can swing quickly from mild to raw and rainy, so it’s smart to:

• Check the forecast the morning of your plans.
• Pick alternate indoor options (museums, the Georgia Aquarium, indoor markets) in case rain moves in.
