Running in Atlanta in September: FAQ
Is it good to run in Atlanta in September?
Generally yes, with sensible timing. The typical daytime Run Score is 69 (Good), with temperatures around 73°F (23°C) and noticeable dew points. The best window is usually 6–9 AM.
How hot is it for running in Atlanta in September?
Typical temperatures average 73°F (23°C) (Warm) with dew points near 61°F. Dew point — not the thermometer — usually decides how hard the run feels.
What is a good Run Score?
Scores run 0–100. 97+ is Perfect, 80–96 is Great — conditions are actively working in your favour. 65–79 (Good) is solid. 45–64 (Mixed) means at least one factor — usually heat or dew point — is taxing you. Below 45 (Poor), expect a noticeably harder effort or hold back for safety.
Why does dew point matter more than temperature?
Your body cools by evaporating sweat. When the dew point climbs above roughly 60°F, the air is too saturated for sweat to evaporate efficiently, so heat builds up even if the thermometer looks reasonable. That's why a 70°F muggy morning can feel harder than a dry 80°F afternoon.
