Weather in Metro Atlanta: What to Expect Through the Year

Metro Atlanta’s weather can feel like a little bit of everything: steamy summers, mild winters, sudden thunderstorms, and the occasional surprise ice event. Understanding Atlanta’s climate helps you plan your days, your wardrobe, and even your commute.

This guide walks through typical weather patterns in Metro Atlanta, what to expect in each season, and how it affects daily life across the region—from downtown and Midtown to Sandy Springs, Decatur, Marietta, and beyond.

Atlanta’s Climate at a Glance

Atlanta sits in the humid subtropical climate zone. That means:

• Hot, humid summers
• Mild to cool winters
• Plenty of rain spread throughout the year
• Occasional severe storms, including thunderstorms and remnants of tropical systems
• Rare but disruptive snow and ice events

You’ll notice that weather can change quickly. A sunny morning in Buckhead may turn into a thunderstorm by late afternoon, especially in summer.

Typical Weather by Season in Metro Atlanta

The chart below gives a general sense of what the year looks like across the metro.

These are general patterns; day-to-day conditions can vary across areas like Cobb, Gwinnett, DeKalb, and Clayton counties, but overall the metro moves together.

Winter in Metro Atlanta (December–February)

Temperature and Feel

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

• Daytime highs often in the 50s to low 60s
• Nighttime lows commonly in the 30s and 40s
• Occasional dips below freezing, especially overnight

You’ll see some days where you can comfortably walk the BeltLine in a light jacket, and others where you’ll want a heavier coat first thing in the morning.

Rain, Snow, and Ice

• Rain is more common than snow.
• Snowfall is usually light when it happens—sometimes just a dusting.
• The bigger concern for Atlanta is often freezing rain and black ice, especially on roads and bridges.

Elevated roadways on interstates like I‑75, I‑85, I‑20, and the Downtown Connector can become slippery quickly during winter events. Even small amounts of ice can cause major traffic problems.

What Locals Typically Do

• Keep a warm coat and waterproof footwear for cold, wet days.
• Allow extra commute time when temperatures drop below freezing and rain is in the forecast.
• Pay attention to Atlanta-Fulton County Emergency Management Agency (AFCEMA) alerts for winter weather advisories and road conditions.

Spring in Metro Atlanta (March–May)

Temperature and Transition

Spring in Atlanta can feel like a fast climb from cool mornings to summer-like afternoons:

• Early spring: highs often in the 60s and low 70s, cool nights
• By late spring: highs regularly in the 80s, more humid

You’ll notice days that start off chilly in the suburbs like Johns Creek or Peachtree City and turn warm by mid-afternoon.

Pollen and Air Quality

Spring is peak pollen season in Metro Atlanta:

• Yellow-green pollen dust can cover cars, patios, and streets.
• Trees and grasses across the region contribute heavily, especially in wooded neighborhoods around Chamblee, Dunwoody, and East Cobb.

People commonly adjust their outdoor time, keep windows closed, and use air conditioning more often during high-pollen days.

Storms and Severe Weather

Spring is an active season for:

• Thunderstorms
• Heavy downpours
• Occasional hail and strong winds

Some storms can become severe, so you’ll often hear about watches and warnings from the National Weather Service office in Peachtree City, which covers Metro Atlanta.

Practical Tips for Spring

• 🌧️ Keep an umbrella or light rain jacket handy, especially in April and May.
• 🤧 Plan outdoor activities earlier in the day or after rain, when pollen can be somewhat lower.
• Monitor weather apps or local media for severe thunderstorm or tornado watches.

Summer in Metro Atlanta (June–August)

Heat and Humidity

Summer is where Atlanta’s humid subtropical climate really shows:

• Highs often in the upper 80s to mid-90s
• Humidity makes it feel hotter, especially in low-lying areas
• Overnight lows usually stay in the 70s, especially in the urban core

Downtown, Midtown, and Buckhead can feel warmer than outlying suburbs due to the urban heat island effect—more pavement and buildings, less shade and green cover.

Afternoon Thunderstorms

A classic Atlanta summer pattern:

• Mornings can be sunny and calm.
• Afternoon thunderstorms bubble up, especially on hot days.
• Storms may be brief but intense, with heavy rain, gusty winds, and frequent lightning.

This can affect:

• Evening commutes on I‑285 and major surface roads
• Outdoor events at places like Piedmont Park, Truist Park, or Mercedes‑Benz Stadium (before or after indoor events)
• Power interruptions in some neighborhoods

Tropical Influences

While Atlanta is not on the coast, remnants of tropical storms or hurricanes from the Gulf of Mexico or Atlantic can bring:

• Extended periods of heavy rain
• Gusty winds
• Local flooding in low-lying areas and near creeks

Areas along Peachtree Creek, South River, and Chattahoochee River can be more prone to high water during these events.

Staying Comfortable in Atlanta Summers

• Plan outdoor exercise earlier in the morning or near sunset when it’s cooler.
• Dress in light, breathable clothing and stay hydrated if you’re walking around Downtown, the BeltLine, or outdoor festivals.
• Watch for heat advisories, especially if you work outdoors or spend long periods outside.

Fall in Metro Atlanta (September–November)

Cooling Temperatures

Fall is often considered the most comfortable season in Metro Atlanta:

• Early fall: highs still in the 80s, gradually easing.
• Mid to late fall: highs slide into the 60s and 70s with cooler nights.

You’ll notice a distinct shift by October, when evenings in Decatur, Smyrna, and Alpharetta start feeling crisp.

Rain and Storms

• Rain chances usually decrease compared to late spring and summer.
• Some early fall days can still see storms, especially in September.
• By late fall, the pattern dries out and becomes more stable.

Fall Foliage and Outdoor Weather

Moderate temperatures and lower humidity make fall ideal for:

• Hiking at places like Stone Mountain, Kennesaw Mountain, or along the Chattahoochee River National Recreation Area
• Festivals and outdoor markets across the metro area
• Comfortable football weather at college and high school stadiums

Microclimates Around Metro Atlanta

While the overall pattern is similar across Metro Atlanta, you may notice small temperature and rainfall differences:

Urban Core vs. Suburbs

• Downtown, Midtown, Buckhead:
  • Often slightly warmer, especially at night
  • More pavement and buildings retain heat
• Outer suburbs and exurbs (e.g., Cumming, Fayetteville, Douglasville):
  • Can be a few degrees cooler, particularly overnight
  • Sometimes see earlier frost in late fall and winter

Elevation Differences

Metro Atlanta has rolling hills, so:

• Higher-elevation areas (parts of Cobb County, North Fulton) can feel just a bit cooler and breezier.
• Lower-lying spots near rivers and creeks may be more humid and fog-prone in cool seasons.

These differences are usually small but noticeable if you drive from one part of the metro to another frequently.

Rainfall and Storm Patterns

Overall Rainfall

Rain is spread across the year, with:

• Often wetter months in late winter, spring, and summer
• Late fall sometimes drier

Short heavy downpours can cause flash flooding, especially:

• Along creeks in DeKalb, Fulton, and Cobb counties
• In low-lying underpasses and older drainage systems in parts of the city

Thunderstorms and Lightning

Thunderstorms are common from late spring through early fall:

• Lightning can be frequent, especially in summer storms.
• Outdoor sports, music events, and festivals sometimes pause or delay activities when storms roll in.

Locals often keep an eye on radar before heading to open areas like Grant Park, Piedmont Park, or the Atlanta BeltLine Eastside Trail on summer afternoons.

Severe Weather Risks in Metro Atlanta

Metro Atlanta does see severe weather, but risk levels vary by season and event type.

Tornadoes

• Tornadoes do occur, though strong ones are relatively rare within the core city.
• Surrounding counties—like Coweta, Paulding, Henry, and Cherokee—have seen more noticeable tornado impacts over the years.
• Tornado risk is often higher in spring and late fall, but storms can happen outside those periods.

Many Atlantans rely on:

• Weather apps with loud alerts
• Local TV and radio
• NOAA Weather Radio, especially in areas more prone to outages

Winter Weather Hazards

Snow and ice are infrequent but disruptive:

• Light snow can accumulate on shaded roads.
• Ice can quickly lead to accidents on major interstates, side streets, and hilly neighborhoods like those around Virginia‑Highland or Morningside.

When winter storms are forecast, schools and workplaces across the metro often adjust schedules in advance.

Flooding

Heavy rain, especially from:

• Slow-moving thunderstorms
• Remnants of tropical systems
• Multi-day rain events

can lead to:

• Flash flooding on smaller creeks and drainage channels
• Ponding on major roads
• Temporary closures of low-lying streets and greenways

Residents near waterways often monitor local forecasts closely and watch for flood advisories.

How Atlanta Weather Affects Daily Life

Commuting

Weather can significantly impact travel across Metro Atlanta:

• Rain: Slows traffic on interstates and surface streets; visibility drops, travel times increase.
• Storms: Downed limbs or power lines occasionally block lanes.
• Ice or snow: Even light accumulations can trigger major delays or closures.

If you depend on MARTA buses or trains, strong storms or winter weather may cause service adjustments, especially on bus routes.

Outdoor Plans and Events

From concerts at Chastain Park to sports at Truist Park or State Farm Arena, weather is built into planning:

• Summer events often include water stations and shaded areas.
• Spring and fall festivals may publish rain plans or reschedule dates depending on forecasts.
• Parks and trails may temporarily close during flooding or high wind events for safety.

Home and Neighborhood Considerations

Metro Atlanta residents often think about:

• Tree maintenance before storm seasons, especially near roofs and power lines.
• Drainage around homes during heavy-rain months.
• Heating and cooling costs, since air conditioning runs heavily in summer and heating is needed on colder winter nights.
