Atlanta’s weather shapes daily life in a big way—from what you wear on your commute, to how you plan weekends at Piedmont Park, to when you book flights through Hartsfield–Jackson. Understanding the weather in Atlanta by season helps you plan smarter and stay comfortable.

Below is a clear, local-focused guide to Atlanta’s climate, typical temperatures, storms, and practical tips for both residents and visitors.

Atlanta’s Climate in a Snapshot

Atlanta has a humid subtropical climate. In plain terms, that means:

• Winters: Generally mild, with occasional brief cold snaps and rare snow.
• Springs: Comfortable but can be stormy, with thunderstorms and pollen.
• Summers: Hot, humid, and often muggy, with afternoon showers.
• Falls: Warm to mild, often considered the most pleasant season.

You’ll notice that humidity and sudden storms are recurring themes, especially from late spring through early fall.

Month‑by‑Month: Typical Atlanta Weather

Use this table as a quick planning guide. Temperatures are typical ranges, not guarantees.

Key takeaway: If you’re coming from a drier or cooler climate, Atlanta will likely feel warmer and more humid than you expect, especially from May through September.

Atlanta Weather by Season

Winter in Atlanta (December–February)

Atlanta winters are relatively short and mild compared to many U.S. cities.

What to expect:

• Daytime temperatures often in the 40s–50s°F
• Nights in the 30s°F, with occasional dips below freezing
• Snow and ice are possible but rare; when they do occur, they can cause significant travel disruptions because the city is not built for heavy snow operations.
• Cold rain is more common than snow.

Practical tips:

• Keep a warm coat, hat, and gloves for colder snaps.
• If there’s a forecast for freezing rain or ice, expect delays on major roads like I‑75, I‑85, and I‑285, and check with Hartsfield–Jackson Atlanta International Airport about potential flight impacts.
• If you live on a hill or in a neighborhood with steep streets, consider stocking some essentials at home when ice is forecast; driving can get hazardous quickly.

Spring in Atlanta (March–May)

Spring is when Atlanta really wakes up, both in weather and in greenery.

What to expect:

• Mild, comfortable days from the 60s–70s°F
• More sunshine, mixed with rainy and stormy days
• Thunderstorms, some strong, especially from late March through May
• High pollen levels, especially from trees and grasses—cars and sidewalks often turn yellowish.

Practical tips:

• For outdoor plans (BeltLine walks, festivals at Centennial Olympic Park, events at Piedmont Park), watch same‑day forecasts; storms can move in quickly.
• Strong storms may bring:
  • Heavy rain
  • Gusty winds
  • Dangerous lightning
• Keep rain gear in your car or bag—light layers plus a compact umbrella usually work well.
• If you are sensitive to pollen, many locals adjust outdoor time when levels are highest and keep car windows closed.

Summer in Atlanta (June–August)

Atlanta summers are hot, humid, and often sticky. This is when “Hotlanta” really feels accurate.

What to expect:

• Daytime highs commonly in the upper 80s to low 90s°F
• High humidity, making it feel even warmer
• Frequent afternoon or early evening thunderstorms
• Warm nights, often staying in the 70s°F

Heat and storms:

• On many days, the heat index (what it feels like with humidity) can be several degrees higher than the air temperature.
• Storms often:
  • Build in the afternoon
  • Bring brief heavy rain and lightning
  • Clear out within an hour or two

Practical tips for summer in Atlanta:

• ☀️ Plan outdoor activities earlier in the morning or closer to sunset when possible.
• Drink water regularly if you’re out at:
  • Atlanta United or Falcons games near Mercedes‑Benz Stadium
  • Concerts at Chastain Park or outdoor festivals
• In heavy downpours, some streets can see quick flash flooding. Low‑lying areas and underpasses can fill with water fast—avoid driving through standing water.
• Air conditioning is standard in housing, MARTA trains, shops, and offices, so bring a light layer if you get cold indoors.

Fall in Atlanta (September–November)

Many locals consider fall the best time of year in Atlanta.

What to expect:

• Warm days in September, gradually cooling
• Lower humidity compared to summer
• Clearer skies and comfortable conditions for outdoor events
• Colorful foliage from mid‑October into November in and around the city

Practical tips:

• This is a prime season for:
  • Hiking close to Atlanta or up toward North Georgia
  • Festivals, sports, and events downtown and in Midtown
• Early fall can still feel like summer, so don’t pack away shorts and T‑shirts too soon.
• Nights grow cooler by late October and November, so layers are useful if you’re out late or catching evening games.

Rain, Storms, and Severe Weather in Atlanta

How Rain Typically Works Here

Atlanta sees rain spread fairly evenly across the year, with a slight increase during late winter and early spring, and frequent summer thunderstorms.

Most rain falls as:

• Light to moderate showers
• Thunderstorms that pass fairly quickly
• Occasional heavier rain systems tied to large weather patterns

Thunderstorms and Lightning

Thunderstorms are a regular part of Atlanta’s warm‑season weather.

They can include:

• Frequent lightning
• Heavy downpours
• Brief gusty winds
• Small hail on occasion

If you’re attending a Braves game at Truist Park, walking the BeltLine, or at an outdoor concert:

• At the first rumble of thunder, seek shelter indoors or in a car.
• Avoid high, open areas and metal bleachers until storms fully pass.

Tornadoes and Severe Weather

Atlanta is not in the very highest‑risk tornado areas of the country, but tornadoes and severe storms do occasionally occur, especially in spring and sometimes in late fall.

Severe weather may bring:

• Damaging straight‑line winds
• Large hail
• Tornado warnings in or near the metro area

What local residents commonly do:

• Pay attention to local alerts on phones, TV, or radio.
• Know an interior room away from windows in their home or workplace where they can go if a tornado warning is issued.
• Avoid driving during intense storms when possible.

Winter Weather: Snow, Ice, and Freezes

While Atlanta is known for warm seasons, winter weather can still matter, mostly because the city is not heavily equipped to handle snow and ice.

Snow

• Light snow events can happen some winters.
• Snowfalls that accumulate significantly on roads are uncommon but impactful.
• Snow can quickly turn to slush or ice, especially when daytime temps are near freezing.

Ice and Freezing Rain

Ice is often more disruptive than snow:

• Even a thin layer of ice can make bridges and interstates dangerous.
• Steep neighborhood roads can become nearly impassable.

During such events, government agencies and schools often:

• Delay openings or close early
• Urge people to stay off the roads until conditions improve

If you’re visiting during a forecasted winter storm, build flexibility into your travel schedule.

Humidity, Air Quality, and Heat in Atlanta

Humidity

High humidity is a constant feature from late spring through early fall.

You may notice:

• Sweat evaporates more slowly, making it feel warmer.
• Early mornings can feel damp or sticky, even before the day heats up.

Most locals adapt by:

• Wearing light, breathable fabrics
• Taking advantage of shade, especially downtown and in urban parks
• Planning the most strenuous activities for earlier or later in the day

Air Quality and Haze

On some summer days, air quality can decline, particularly during stagnant, hot periods.

Common experiences:

• Hazy or less crisp views of the skyline
• Air quality alerts that suggest limiting prolonged outdoor exertion, especially for sensitive groups

People who are more sensitive often adjust by:

• Exercising earlier in the morning
• Spending the hottest, hazier part of the day indoors

How Weather Affects Daily Life in Atlanta

Commuting and Transportation

Whether you rely on I‑20, I‑75, I‑85, I‑285, GA‑400, or MARTA, weather can impact your commute.

• Heavy rain can slow traffic significantly and increase accidents.
• Fog on some mornings may reduce visibility on highways.
• Thunderstorms can briefly disrupt MARTA rail and bus service schedules.
• In rare ice events, bridges, flyovers, and hilly roads become hazardous quickly.

If you drive:

• Allow extra time during storms.
• Be cautious in known low spots and underpasses prone to brief flooding.

If you fly through Hartsfield–Jackson Atlanta International Airport:

• Summer thunderstorms and winter storms can cause delays.
• Build a buffer if you have tight connections on stormy days.

Events, Sports, and Recreation

Outdoor life in Atlanta—festivals, concerts, professional sports, and neighborhood events—is heavily influenced by the weather.

• Spring and fall are peak seasons for outdoor festivals and runs.
• Summer events often plan for cooling stations, shaded areas, and evening start times.
• Sudden storms may pause or delay outdoor events, but they often resume once conditions improve.

If you have tickets or plans:

• Check the day‑of forecast for heat, storms, or chill.
• Bring what you’re likely to need:
  • Light rain jacket or poncho
  • Hat and sunscreen
  • Extra water on hot days
