Below is a clear, season-by-season guide to Atlanta’s climate, typical temperatures, storms, and practical tips tailored to life in the city.

Atlanta’s Climate at a Glance

Atlanta sits in the Piedmont region of north Georgia, with a humid subtropical climate. In plain terms, that means:

• Springs: Warm, often stormy, and very pollen-heavy.
• Summers: Hot, humid, with frequent afternoon thunderstorms.
• Falls: Comfortable, less humid, and often the most pleasant season.

Quick Seasonal Snapshot for Atlanta

Use this table as a rough guide to typical weather patterns. Actual conditions can and do vary.

Winter in Atlanta (December–February)

What It Feels Like

Atlanta winters are short and relatively mild, but they can be unpredictable:

• Many days are cool to mild, with afternoon temperatures in the 50s or 60s.
• Nighttime temps often fall into the 30s or low 40s.
• Hard freezes (below 28°F) do happen but are usually brief.
• Snow and ice are possible but not frequent. When they do occur, even a small amount can disrupt travel.

Snow, Ice, and “Wintry Mix”

Atlanta doesn’t get reliable snow every year, but:

• Light snow or wintry mix (snow/sleet/freezing rain) may occur a few times in a winter.
• Ice is often a bigger issue than snow, especially on:
  • Overpasses and bridges
  • Hilly neighborhood roads
  • Interstates around the city, like I-285, I-75, I-85, and GA-400

When there’s a risk of ice, schools and businesses sometimes delay opening or close, even if accumulation is minor.

How to Prepare for Winter in Atlanta

• Layer your clothing: A light or medium-weight jacket, sweaters, and a rain-resistant layer are usually enough.
• Prepare for cold snaps: Keep gloves, a warm hat, and a heavier coat handy for those few very cold days.
• Drive cautiously in winter weather: Many local drivers are not experienced with ice; if it’s icy, consider avoiding the roads if possible.
• Monitor local updates:
  • National Weather Service Atlanta Office (Peachtree City)
  • Local TV stations and radio for closures and advisories

Spring in Atlanta (March–May)

Warming Temperatures and Storms

Spring in Atlanta is pleasant but active:

• Temperatures usually rise into the 60s and 70s, with some days in the 80s by late spring.
• Thunderstorms become more frequent, especially from March through May.
• Some storms may bring strong winds, hail, or tornado warnings, especially across north and central Georgia.

While severe storms are not an everyday event, it’s important to stay aware of weather alerts, especially if you spend a lot of time outdoors or commuting.

Pollen and Air Quality

Atlanta is well known for its spring pollen season, especially from trees like pine and oak:

• Cars, sidewalks, and outdoor furniture often get coated in a yellow-green dust.
• Many residents experience seasonal allergies and irritation.
• Pollen counts tend to spike on dry, breezy days after a warm-up.

If you’re sensitive to pollen:

• Keep windows closed on high-pollen days.
• Use your home and car air conditioning with recirculation when needed.
• Consider showering and changing clothes after spending time outside to remove pollen.

Practical Spring Tips for Atlanta

• Keep an umbrella or light rain jacket on hand.
• Be aware that outdoor events and festivals can be affected by storms; check forecasts before heading to places like:
  • Piedmont Park
  • Atlanta BeltLine
  • Truist Park or Mercedes-Benz Stadium
• Pay attention to tornado watches and warnings; know your interior shelter area at home or work.

Summer in Atlanta (June–August)

Heat and Humidity

Atlanta summers are hot and humid, especially from late June through August:

• Daytime highs commonly reach the upper 80s and 90s.
• High humidity can make it feel hotter than the actual temperature.
• Nighttime temperatures often stay in the 70s, especially in the city.

This combination can lead to stressful conditions for outdoor work, sports, and long walks, especially in the afternoon.

Afternoon Thunderstorms

A classic Atlanta summer pattern is:

• A hot, humid morning and midday.
• Pop-up thunderstorms in the afternoon or early evening.
• Storms may be brief but intense, bringing:
  • Heavy rain
  • Lightning
  • Gusty winds
  • Localized flooding on low-lying streets and underpasses

Areas with frequent pooling water can include:

• Downtown and Midtown underpasses
• Low spots along major corridors when drainage is overwhelmed

Staying Safe and Comfortable in Summer

• Hydrate regularly: Especially if walking around Downtown, Midtown, or popular outdoor spots.
• Plan outdoor activities for early morning or evening: Cooler and often less humid.
• Use sun protection: Shade, hats, and sunscreen are important when visiting:
  • Atlanta Botanical Garden
  • Zoo Atlanta
  • Outdoor festivals and concerts
• When storms are forecast:
  • Move indoors when you hear thunder.
  • Avoid parking under large trees during high-wind events.

Fall in Atlanta (September–November)

Generally the Most Pleasant Season

Many locals consider fall the best time for Atlanta weather:

• Daytime highs usually settle into the 60s and 70s.
• Nights become cooler, in the 40s and 50s, especially by late October and November.
• Humidity drops, making the air feel more comfortable.

Fall Color and Outdoor Activities

Thanks to Atlanta’s many trees, fall can bring colorful foliage, especially in:

• Intown neighborhoods with mature trees
• Parks like Piedmont Park, Grant Park, and Chastain Park
• Nearby areas like Stone Mountain or north Georgia mountains (a popular day trip)

Rain still occurs, but generally less intense heat and fewer storms than in summer.

How to Plan for Atlanta Fall Weather

• Keep layers handy: mornings can be cool while afternoons are warm.
• Fall is ideal for:
  • Walking the Atlanta BeltLine
  • Visiting outdoor markets
  • Attending college and professional football games
• Watch for early cold fronts in October and November that can bring quickly dropping temperatures.

Severe Weather and Storms in Atlanta

Thunderstorms, Lightning, and Heavy Rain

Thunderstorms can occur any time of year, but are most common in spring and summer:

• Lightning can develop quickly, even with storms that look distant.
• Short bursts of heavy rain can cause ponding and localized flooding, particularly:
  • Along smaller creeks and streams
  • On busy roads with poor drainage

If you’re driving and encounter heavy rain:

• Slow down and increase following distance.
• Avoid driving through standing water where depth is unclear.
• If visibility is very low, safely pull over to a secure area until conditions improve.

Tornado and Severe Weather Awareness

While tornadoes are not daily events in Atlanta, tornado watches and warnings do occur:

• A watch means conditions are favorable.
• A warning means a tornado has been indicated or seen; you should move to your safest indoor spot.

In multi-story buildings in Atlanta:

• Go to the lowest floor possible, away from windows.
• Choose an interior hallway, bathroom, or stairwell.

Who Provides Official Weather Alerts in Atlanta?

For residents and visitors, official alerts come from:

• National Weather Service (NWS) – Atlanta/Peachtree City Office
  4 Falcon Drive, Peachtree City, GA 30269
  General forecast and warnings for the Atlanta metro area.

• Fulton County Emergency Management Agency (EMA)
  Offers county-level emergency preparedness and alert information for much of the city.

Many people also sign up for county or city alert systems for text or email notifications about tornado warnings, flash flooding, and other emergencies.

Hurricanes and Tropical Weather in Atlanta

Atlanta is not on the coast, but tropical systems from the Gulf of Mexico or Atlantic can still affect the city:

• Remnants of hurricanes and tropical storms can bring:
  • Heavy rain
  • Gusty winds
  • Isolated tornadoes and power outages
• These impacts are usually weaker than on the coast, but can still disrupt travel and outdoor plans.

During tropical weather impacts:

• Secure or bring in loose outdoor items (patio furniture, grills, yard decorations).
• Check forecasts if you’re traveling to Hartsfield-Jackson Atlanta International Airport, as flights can be delayed by heavy rain and storms.
• Be prepared for short-term power interruptions, especially in heavily treed neighborhoods.

Microclimates Around Atlanta

Even within metro Atlanta, you may notice small differences in weather depending on where you are:

• Urban Core (Downtown, Midtown, Buckhead):
  • Often slightly warmer, especially at night, due to buildings and pavement.
• Suburban and Outlying Areas (Sandy Springs, Decatur, South Fulton, Cobb, Gwinnett):
  • Can be a bit cooler overnight and may see more frost in winter.
• Hilly or Higher-Elevation Neighborhoods:
  • Sometimes experience slightly cooler temperatures and different wind patterns.

These differences are usually small, but can matter for gardening, commuting conditions, and outdoor events.
