Seasonal Weather in Atlanta, GA

Spring in Atlanta (March–May)

Spring is one of the most comfortable times in Atlanta, but also one of the most changeable.

What you can expect:

• Temperatures: Often mild, with cool mornings and warm afternoons
• Rain: Regular showers and some heavier thunderstorms
• Pollen: Tree and grass pollen can be intense in March and April
• Storms: Occasional strong thunderstorms, sometimes with hail or gusty winds

How to plan:

• Keep a light jacket and umbrella handy.
• If you spend time around Piedmont Park, the BeltLine, or outdoor festivals, watch the forecast for storms in the afternoon or evening.
• Check air quality and pollen levels if you’re sensitive to seasonal conditions.

Summer in Atlanta (June–August)

Summer in Atlanta is hot, humid, and often stormy in the afternoons.

Typical summer patterns:

• Daytime highs: Often in the upper 80s to 90s, sometimes higher during heat waves
• Humidity: High, which makes it feel hotter than the actual temperature
• Storms: Pop-up thunderstorms are common, especially late afternoon and early evening
• Overnight: Warm and muggy, especially in the city center

Local tips for summer:

• Plan outdoor activities early in the morning or closer to sunset.
• If you’re walking around Downtown, Midtown, or Buckhead, be prepared for heat radiating from streets and buildings.
• Many Atlantans rely on short-term radar and lightning alerts during summer to know when to stay indoors.

Fall in Atlanta (September–November)

Fall is often one of the most pleasant seasons in Atlanta, with more comfortable temperatures and colorful foliage.

What you’ll notice:

• Early fall (September): Still quite warm, often feeling like late summer
• Mid to late fall (October–November): Cooler mornings and evenings, comfortable afternoons
• Rain: Periodic showers but fewer storms than summer
• Leaves changing: Noticeable color in areas like Grant Park, Inman Park, and city neighborhoods with mature trees

How to use the forecast:

• Great time for parks, tailgates, festivals, and hiking in and around Atlanta.
• Dress in layers – mornings may be cool, afternoons pleasantly warm.

Winter in Atlanta (December–February)

Winters in Atlanta are usually mild compared to northern cities, but the area does see cold snaps, freezing nights, and occasional winter weather events.

Key winter features:

• Typical temperatures: Chilly mornings, cool to mild afternoons
• Freezing temperatures: Not every night, but common enough to matter
• Snow/ice: Infrequent, but ice storms or light snow can disrupt travel significantly
• Cold rain: More common than snow, and can feel raw and damp

Why small winter events matter here:

• Roads and bridges around I-285, I-75, I-85, and GA 400 can become dangerous with even a thin layer of ice.
• Because winter storms are less frequent, the city can be more sensitive to school and business disruptions when they do happen.

Common Atlanta Weather Hazards to Watch

Thunderstorms and Lightning

Thunderstorms are very common, especially from late spring through early fall.

You may see:

• Heavy downpours with localized flooding
• Frequent lightning
• Gusty winds and occasional hail

If you’re at outdoor events, sports fields, Piedmont Park, or rooftop venues, it’s smart to:

• Check the hourly forecast and radar before heading out.
• Move indoors if you hear thunder; storms can develop quickly.

Heat and Humidity

During hot spells, the heat index (what it feels like) can be higher than the actual temperature.

This matters if you:

• Work or exercise outside
• Use MARTA and spend time at outdoor or partially covered stations
• Attend festivals, concerts, or games at outdoor venues

Practical habits:

• Look at “feels like” temperatures in addition to the actual number.
• Plan breaks in indoor, air-conditioned spaces when exploring Downtown, Midtown, or the Westside by foot.

Heavy Rain and Flash Flooding

Short but intense rain events can cause flash flooding, especially in:

• Low-lying intersections
• Underpasses along major roads
• Areas near creeks and streams

If the forecast mentions flood advisories or warnings:

• Avoid driving through standing water on roads.
• Give extra time for commutes along I-20, I-75/85, I-285, and surface streets that tend to back up in storms.

Tornado and Severe Weather Risk

Atlanta and the surrounding metro area do experience severe thunderstorms, and tornadoes are possible, though not daily.

When forecasts mention “severe weather risk” or tornado watches/warnings:

• Know where your indoor safe space is (interior room on the lowest floor, away from windows).
• Enable notifications for tornado warnings and severe weather alerts on your phone for your Atlanta location.

How Atlanta’s Microclimates Can Affect You

Even within the city, weather can feel different from one neighborhood to another.

Some patterns locals notice:

• Urban heat: Downtown, Midtown, and Buckhead can feel hotter than shaded neighborhoods with more trees.
• Elevation changes: Parts of Atlanta are hillier; higher spots can feel slightly cooler and breezier.
• Tree cover: Areas like Druid Hills, Virginia-Highland, and Decatur often feel cooler in summer because of shade.

When checking the weather, it helps to look specifically at your ZIP code or neighborhood instead of just a generic “Atlanta, GA” reading.

Using Atlanta Weather Information in Daily Life

Planning Your Commute

Weather has a direct impact on traffic and public transit:

• Heavy rain, thunderstorms, or winter weather can slow traffic on I-75, I-85, I-20, GA 400, and the Downtown Connector.

Check the forecast when:

• Scheduling early morning or late-night drives

Weather tips:

• For outdoor venues (parks, amphitheaters, open-air markets), use:
  • Hourly forecasts to time arrival and departure
  • Rain chances and thunderstorm timing in summer
• For evening events, especially in spring and fall:
  • Carry a light layer – it can cool off quickly after sunset.

Home and Property Considerations

Atlanta weather can influence how you manage your home:
