Typical Temperatures in Atlanta, Georgia: What to Expect All Year

If you’re wondering “What is the temperature in Atlanta?” the honest answer is: it depends on the time of year, the time of day, and even the humidity. Atlanta’s weather is known for hot, humid summers, mild winters, and frequent temperature swings between seasons.

This guide walks through average temperatures in Atlanta by season and month, what those numbers actually feel like, and how locals typically plan around the weather.

Atlanta’s Climate at a Glance

Atlanta has a humid subtropical climate. That means:

• Summers: Hot, often humid, with many days in the upper 80s to 90s°F
• Winters: Generally mild, but short cold snaps and freezing nights do occur
• Spring & Fall: Comfortable, but temperatures can jump up or down quickly
• Rain & storms: Thunderstorms are common in warmer months, which can make it feel hotter or cooler than the actual temperature

Here’s a simple overview of average daytime highs and overnight lows in Atlanta through the year. These are long-term typical values, not today’s forecast.

Average Atlanta Temperatures by Month

These are averages, so any given day can be warmer or colder. Heat waves in summer and cold snaps in winter are normal.

Seasonal Temperatures in Atlanta

Winter in Atlanta (December–February)

Typical temperature range:

• Daytime: mid‑40s to mid‑50s°F (7–13°C)
• Night: low‑30s to upper‑30s°F (0–4°C)

What to expect:

• Many winter days are cool but not freezing, especially in the afternoon.
• Freezing nights are common, especially in January and early February.
• Snow and ice are possible but usually limited; some winters see only flurries or cold rain.
• Lakes, shaded parks, and higher spots in the metro (like parts of North Fulton or Cobb) can feel a bit colder than central Atlanta.

Practical tips:

• Black ice can form on roads and bridges after rain and overnight freezing temperatures.

Spring in Atlanta (March–May)

Typical temperature range:

• March: 60s°F days, 40s°F nights
• May: upper‑70s to low‑80s°F days, around 60°F nights

What to expect:

• Early spring can swing between chilly mornings and mild afternoons.
• By April and May, many days feel comfortable and warm, often ideal for outdoor activities.
• Pollen (especially from trees) is significant, which many residents notice more than the temperature itself.

Practical tips:

• Outdoor events at places like Piedmont Park, the Atlanta BeltLine, or Botanical Garden are popular in this season because temperatures are usually pleasant.

Summer in Atlanta (June–August)

Typical temperature range:

• Daytime: mid‑80s to low‑90s°F (29–34°C)
• Night: upper‑60s to low‑70s°F (20–23°C)

This is when many people most notice “Atlanta heat.”

What to expect:

• Many afternoons feel hot and humid, especially in July and August.
• The heat index (what it feels like with humidity) can make mid‑80s° days feel like 90°F+.
• Afternoon thunderstorms are common, briefly cooling the air but often leaving it more humid afterward.
• Heat tends to linger in built-up areas like Downtown, Midtown, and Buckhead due to concrete and traffic (urban “heat island” effect).

Practical tips:

• ☀️ Plan strenuous outdoor activities (like running the BeltLine) early in the morning or closer to sunset.
• Light, breathable clothing is most comfortable.
• Air conditioning is widely used in homes, offices, MARTA trains, and most public buildings.

Fall in Atlanta (September–November)

Typical temperature range:

• September: low‑80s°F days, mid‑60s°F nights
• November: low‑60s°F days, mid‑40s°F nights

What to expect:

• Early fall (September) can still feel summery during the day.
• By October and November, many days are clear, dry, and mild, with crisp mornings and evenings.
• This is often considered one of the most comfortable times temperature-wise in Atlanta.

Practical tips:

• A light jacket or sweater is handy for mornings and nights.
• Outdoor festivals, sports events, and patio dining are common because temperatures are usually manageable.

How Humidity Affects Atlanta Temperatures

Even if the thermometer says one thing, humidity changes how the temperature feels. In Atlanta:

• Summer humidity is usually high, which:
  • makes hot days feel hotter
  • slows down sweat evaporation, so your body cools less effectively
• In winter, the air can feel relatively damp, making cool or cold days feel raw and more penetrating.

You will often see local forecasts mention:

• “Feels like” temperature – factoring in humidity (in summer) or wind (in cooler months)
• Heat index – used in hot weather to describe how the combination of heat and humidity affects the human body
• Wind chill – occasionally in winter when it’s windy and below about 50°F

Day vs. Night Temperatures in Atlanta

Atlanta typically has a noticeable drop from daytime to nighttime temperatures, especially outside summer.

• In winter, nights are often 10–15°F colder than daytime highs.
• In summer, the city tends to stay warm overnight, often remaining in the 70s°F.

Areas with more trees and less pavement, such as near Chastain Park, Grant Park, or along the Chattahoochee River, can feel a bit cooler at night than dense urban neighborhoods.

Microclimates Across the Atlanta Area

While official temperatures are usually reported from Hartsfield–Jackson Atlanta International Airport, you might feel small differences across the metro:

• Intown neighborhoods (Midtown, Downtown, Old Fourth Ward, Buckhead):
  Often a little warmer, especially at night, due to buildings and pavement.
• Suburban and outer areas (Marietta, Alpharetta, Peachtree City, Stone Mountain):
  Can be slightly cooler, particularly in the early morning.
• Higher elevations north of the city:
  Sometimes a few degrees cooler, especially in winter mornings.

These differences are usually modest (often just a few degrees), but you may notice them if you move around the region frequently.

Where to Check the Current Temperature in Atlanta

For up-to-the-minute temperature and forecasts for Atlanta, many residents rely on:

• National Weather Service (NWS) – Atlanta Office
  • Based in Peachtree City, GA
  • Main phone (public line often listed): (770) 486-1133
  • Provides official current conditions, hourly forecasts, and weather alerts for the Atlanta metro.

You can also get current Atlanta temperatures from:

• Local TV stations based in Atlanta
• Weather apps and smartphone widgets
• Radio weather updates, especially during storms or extreme heat/cold

When planning your day, especially in summer or during potential winter ice events, it’s useful to check both:

• The current temperature
• The expected high/low and “feels like” temperature
