Atlanta Weather by Season
Summer (June–August): Hot, Humid, and Stormy
Atlanta summers are typically:
- Daytime highs: Often in the upper 80s to mid-90s °F
- Humidity: High, making it feel hotter than the actual temperature
- Rain: Frequent afternoon and evening thunderstorms
Common experiences in Atlanta summers:
- You may start the day clear and sunny, then see clouds build and thunderstorms hit suddenly mid- to late afternoon.
- Short, heavy downpours can lead to localized street flooding, especially in low-lying areas and near creeks.
- Heat indexes can climb into the upper 90s or above, especially downtown and around major roads where the “urban heat island” effect kicks in.
💡 Local tips for summer:
- Keep light, breathable clothing and a compact umbrella or rain jacket handy.
- If you’re outdoors at places like Piedmont Park or the Atlanta BeltLine, try to plan long walks or runs for early morning or later evening.
- In very hot stretches, seek public cooling options like malls, libraries, or large indoor attractions such as Ponce City Market or Atlanta History Center.
Fall (September–November): One of the Best Times to Be Outside
Fall in Atlanta is usually:
- Warm to mild early (September), cooling steadily by November
- Less humid than summer, much more comfortable
- A mix of crisp mornings and pleasant afternoons
You can expect:
- September may still feel like an extension of summer, especially early in the month.
- By October and November, daytime highs often fall into the 60s and 70s, with cooler nights.
- Colorful fall foliage appears across parks like Grant Park, Freedom Park, and Chastain Park, depending on the year and temperature trends.
🍂 Local tips for fall:
- Layers work best—think light jacket or hoodie in the morning, T-shirt weather by afternoon.
- It’s a prime season for outdoor events, festivals, and sports, so watch for cool evenings if you’re out at Mercedes-Benz Stadium or Truist Park.
Winter (December–February): Mostly Mild, Occasionally Icy
Winter in Atlanta is often:
- Mild overall, with some cold snaps
- A mix of chilly rain, clouds, and occasional sunny days
- Rarely very snowy, but ice events are possible
Typical patterns:
- Daytime highs: Frequently in the 40s and 50s °F
- Nighttime lows: Often in the 30s, occasionally dipping below freezing
- Wintry weather: Light snow or sleet is possible some years, and ice can be more of a problem than snow
The city is not built for regular snow and ice, so even small accumulations can disrupt roads, schools, and transit. Bridges and overpasses, including portions of I-75, I-85, and the Downtown Connector, can become slick quickly.
❄️ Local tips for winter:
- Keep a coat, hat, and gloves handy, especially for early mornings and late nights.
- Watch for freezing rain or “wintry mix” forecasts, which can impact commutes and flights through Hartsfield-Jackson Atlanta International Airport.
- If you must drive in icy conditions, many Atlantans allow extra time, avoid steep hills and side streets, and stick to major roads that are treated more quickly.
Spring (March–May): Pleasant, Pollen-Filled, and Storm-Prone
Spring in Atlanta is:
- Often comfortable by day and cool at night
- Known for pollen season, especially from trees and grasses
- A time when strong thunderstorms can appear
You’ll notice:
- Rapid swings from cooler to warmer days, especially in March.
- By April and May, many afternoons are warm and pleasant, often in the 70s and low 80s.
- Yellowish-green pollen dust on cars, sidewalks, and outdoor furniture, especially late March through April.
⛈️ Local tips for spring:
- Keep a light rain jacket and umbrella available.
- Follow local weather updates for thunderstorm watches and warnings, particularly in the afternoon and evening.
- If you have outdoor plans at places like Atlanta Botanical Garden or the Zoo Atlanta area, check the day’s forecast for any storm timing.

Typical warm-season experiences:
- Midday and late afternoon outdoors can feel draining or oppressive.
- Areas with lots of pavement and limited shade, such as some parts of Downtown, Midtown, and Buckhead, often feel hotter than nearby shaded neighborhoods.

Winter Weather: Snow, Sleet, and Ice in Atlanta
While snow is not a regular feature every winter, when it does appear, even a little can cause significant disruption.
Winter weather can include:
- Light snow that melts quickly
- Sleet and freezing rain, which can coat roads, sidewalks, and power lines
- Travel delays near Hartsfield-Jackson and along major interstates
Because Atlanta roads and local drivers are not accustomed to frequent snow or ice:
- Many residents stay off the roads during active winter storms.
- Schools and local government may delay or close when conditions look unsafe.
- Icy conditions on hills and side streets can remain an issue even after main roads improve.
🧊 If winter weather is in the forecast:
- Check for official updates from City of Atlanta and surrounding counties regarding closures and road conditions.
- Keep some basic essentials at home so you don’t need to drive if conditions worsen unexpectedly.
- Use extra caution on shaded roadways, bridges, and overpasses where ice lingers.

You’ll often see:

- Increased sniffles and irritation for those sensitive to tree or grass pollen
- Outdoor furniture needing regular rinsing during peak weeks
On certain days, air quality can also be affected by:
- Ozone levels, especially during hot summer afternoons
- Smoke from regional fires when conditions funnel smoke into the city
🌳 Local habits during heavy pollen or poor air quality:
- Many people keep windows closed and use air conditioning or air filtration.
- Outdoor plans might be shifted to times of day when pollen or ozone impacts are lower, depending on personal sensitivity.
- Some Atlantans rinse off porches, cars, and outdoor spaces frequently during the heaviest pollen days.
