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 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.
Below is a simplified look at typical temperatures in Atlanta. Actual numbers vary year to year, but these ranges reflect what residents and visitors commonly experience.
| Season | Typical Highs (°F) | Typical Lows (°F) | What It Feels Like |
|---|---|---|---|
| Winter | Mid‑40s to mid‑50s | Low‑30s to low‑40s | Mostly mild, occasional cold snaps and freezes |
| Spring | Low‑60s to mid‑70s | Mid‑40s to mid‑50s | Pleasant, can swing cool to warm quickly |
| Summer | Mid‑80s to low‑90s | Upper‑60s to low‑70s | Hot and humid, sticky afternoons |
| Fall | Mid‑60s to mid‑70s | Upper‑40s to mid‑50s | Comfortable, less humid, cooler nights |
