Atlanta’s weather is famously changeable, but there is a pattern once you know what to look for. Whether you live in the city, commute in for work, or are planning a visit, understanding Atlanta’s monthly weather helps you pack the right clothes, plan outdoor time, and prepare for storms, heat, and pollen.

Below is a month‑by‑month guide to typical conditions in Atlanta, Georgia, plus tips tailored to local life.

Quick Overview: Atlanta Weather by Month

Use this as a fast reference for typical conditions. Actual weather can vary from year to year.

Atlanta’s Climate in Plain Terms

Atlanta has a humid subtropical climate. For residents and visitors, that usually means:

• Hot, humid summers with frequent afternoon thunderstorms
• Mild to cool winters, with only occasional ice or snow
• Long spring and fall seasons with big swings in temperature
• Plenty of rain spread across the year, not just one “rainy season”

Because Atlanta is a little higher in elevation than many Southern cities, it can feel slightly cooler than places along the coast, but humidity and summer heat are still very noticeable.

For day‑to‑day local forecasts, many people check the National Weather Service Atlanta office (Peachtree City), which covers the metro area:
