Dew Point in Atlanta — Frequently Asked Questions
What's the highest dew point ever in Atlanta?
The highest value in Atlanta's 1995–2024 reanalysis record is 79°F, reached on August 16, 2017. That is the same 30-year window the monthly table above uses — not an official observing-station record, which is a different and shorter dataset. The median July dew point reaches about 69°F, so the all-time mark sits roughly 10°F above a normal summer high.
Is Atlanta more humid or dry?
Dry for most of the year. The median dew point sits below the sticky range from October through May. Atlanta's sticky stretch runs June–September, peaking at a median of 69°F.
Is Decatur as humid as Atlanta?
The two cities share the same air mass, so their sticky days line up closely — when one turns muggy, the other usually does within a day. The table above shows the current readings side by side.
What is a comfortable dew point in Atlanta?
The comfort scale is the same everywhere: a dew point between 50°F and 60°F (10–16°C) feels comfortable to most people in Atlanta, 60–65°F starts to feel sticky, and anything above 70°F feels oppressive. Local climate changes how often you see each range, not how it feels.
How often does the Atlanta dew point update?
The reading on this page refreshes every 30 minutes from Open-Meteo, and the timestamp shown is Atlanta local time. Dew point moves slowly compared with air temperature, so a recent reading is reliable for planning the next few hours.
Why is dew point better than the humidity percentage?
Relative humidity changes meaning with the temperature — 50% is dry on a cool morning and oppressive on a hot afternoon. Dew point is absolute, so 65°F always represents the same amount of moisture and the same sticky feeling.
