Average Weather in Atlanta: What to Expect Month by Month
Atlanta’s weather is famously changeable: you can get a warm afternoon in January and a chilly morning in April. Still, there are clear patterns that locals rely on when planning commutes, outdoor events, and visits to places like Piedmont Park, the BeltLine, or downtown.
This guide breaks down the average weather in Atlanta, Georgia through the year so you know what to pack, what to wear, and how to plan your days.
Atlanta’s Climate at a Glance
Atlanta has a humid subtropical climate. In practical terms, that means:
- Winters: Generally mild, short, and often wet
- Springs: Warm, breezy, and pollen-heavy
- Summers: Hot, humid, with frequent afternoon storms
- Falls: Comfortable, drier, and great for outdoor activities
Atlanta’s elevation (around 1,000 feet above sea level) keeps it slightly cooler than many other Southern cities at similar latitudes, but heat and humidity are still a big part of life here.

Thunderstorms and Lightning

Snow and Ice: How Often Does Atlanta Get Winter Weather?
Atlanta’s average winter brings:
- Mostly rain and chilly days
- A few freezing nights each year
- Infrequent snow or ice, but impactful when it happens
When snow or ice does arrive, even in small amounts:
- Roads and interstates (like I‑75/85 through downtown) can become very slick
- School and office closings are more common than in cities accustomed to heavy snow
Locals often monitor winter forecasts closely and adjust travel plans quickly when winter storms are mentioned.
Humidity and “Feels Like” Temperatures
Atlanta’s humidity is a major factor, especially from late spring through early fall.
- Summer humidity makes it feel hotter than the air temperature
- Morning commutes can already feel muggy, and evenings may not cool off much
- Air conditioning is standard in homes, offices, MARTA trains, and most public buildings
When you see “feels like” or heat index values in forecasts, those numbers often matter more for comfort than the actual temperature, especially in July and August.
Air Quality, Pollen, and Seasonal Comfort
Pollen
Atlanta is known for strong spring pollen seasons, especially March through April:
- Pine pollen is highly visible (the yellow dust on cars and sidewalks)
- Other tree, grass, and weed pollens contribute to seasonal discomfort
If you’re sensitive to pollen, many residents:
- Keep windows closed during peak days
- Use air conditioning and change home filters regularly
- Avoid extended time outdoors during early morning when pollen counts can be higher
For pollen forecasts specific to Atlanta, local media and weather services often provide daily updates.
Air Quality
On some hot, still summer days, ozone and particulate levels can rise, leading to lower air quality. These days are more likely:
- During heat waves
- When there’s little wind or air movement
Residents who are concerned about air quality often follow local “air quality alerts” shared by the Georgia Environmental Protection Division (EPD) and local news outlets.
