How Cold Does Atlanta Get in January?
Daytime: Chilly but Often Manageable
During the day, Atlanta’s January weather usually feels:
- Cool to cold, but not brutal by northern standards
- Comfortable with a medium-weight jacket, especially in the sun
- Noticeably colder on damp or windy days
If you’re walking around Downtown, Midtown, or Buckhead, expect to want:
- A coat or insulated jacket
- Long sleeves or a light sweater underneath
- Something to cover your ears/hands if you’ll be outside for a while
Nighttime: Expect a Real Chill
Once the sun goes down, temperatures regularly dip:
- Into the 30s°F, sometimes just below freezing
- Colder in open or higher spots, like the northern suburbs
If you’re going out in the evening—say to events around State Farm Arena, Mercedes-Benz Stadium, or the BeltLine—plan for:
- A warmer coat
- Hat and gloves on colder nights
- Closed shoes or boots rather than sandals or thin sneakers
Does It Snow in Atlanta in January?
Snow Is Possible, But Not Guaranteed
Atlanta can get snow or wintry mix in January, but:
- Snow events are usually brief and light
- Many years see little or no measurable snow
- When snow or ice does hit, even a small amount can disrupt travel and schedules
You’re more likely to see:
- Cold rain
- A rain/sleet mix
- Black ice on bridges and overpasses on very cold mornings
Why Small Storms Cause Big Problems
Atlanta isn’t built for heavy winter weather. When a January winter event hits:
- Roads can ice over quickly
- Traffic can slow or stall
- Schools and some offices may close or delay opening
This is especially true on hilly neighborhoods and elevated roadways, such as:
- Interchanges on I‑75, I‑85, I‑285, and GA‑400
- Higher spots in North Atlanta, Sandy Springs, Dunwoody, and Buckhead
If a winter weather advisory is issued, many locals adjust travel plans or stay home where possible.
Rain, Clouds, and Sunshine in January
A Generally Gray, Damp Month
January in Atlanta tends to be:
- Cloudier and wetter than fall
- Marked by frequent light to moderate rain, sometimes for a day or two at a time
You’ll notice:
- Wet streets and puddles are common
- Occasional heavier showers with passing cold fronts
- A damp chill, especially in the mornings or after sunset
Sun Breaks Still Happen
Between systems, Atlanta often enjoys:
- Clear, bright days that still feel crisp
- Afternoons that can feel surprisingly mild in the sun
On these days, outdoor spots like Piedmont Park, the Atlanta BeltLine, and parks in Decatur or Grant Park can feel very comfortable with a light jacket.
What to Wear in Atlanta in January
Daily Clothing Basics
For most January days in Atlanta, a layered approach works best:
- Base layer: T‑shirt or long-sleeve shirt
- Middle layer: Light sweater, fleece, or sweatshirt
- Outer layer: Medium-weight jacket or coat
This lets you adjust when moving between:
- Colder mornings and milder afternoons
- Heated MARTA trains, offices, malls, and restaurants
- Windy versus sheltered areas downtown
Shoes and Accessories
Consider:
- Closed-toe shoes or ankle boots
- Water-resistant footwear on rainy days
- Umbrella or rain jacket—showers are common
- Hat, scarf, gloves for colder snaps or evening events
Visitors from warmer climates (like Florida or the Caribbean) often find January in Atlanta colder than expected, especially with the damp air and wind.
Driving and Transportation in January Weather
Normal Days: Just Cool and Sometimes Wet
On most January days, Atlanta roads are:
- Fully passable, just wet during or after rain
- Busy with typical rush-hour congestion on I‑75/85, I‑20, and I‑285
You’ll mainly want to:
- Use headlights and extra caution in heavy rain
- Watch for standing water during downpours
- Allow extra time for low-visibility mornings with fog or drizzle
Icy Days: Rare but Serious
On the less common icy mornings or snow days:
- Bridges, ramps, and overpasses can freeze first and worst
- Residential streets, especially in hilly neighborhoods, may be slick
- Some locals opt to work remotely or delay travel
If you must drive during possible winter weather:
- Check conditions through local news, 511 Georgia road updates, or navigation apps
- Consider major roads first, which are more likely to be treated or cleared
- Drive slowly and avoid sudden braking or sharp turns
Public transit via MARTA (rail and many bus routes) may run modified schedules in severe weather, so it’s wise to verify service before you head out.
