A live Georgia AQI map shows the current air quality index for each monitored city, color-coded Good to Hazardous. Read two things: the number and the pollutant driving it.
TL;DR
Georgia’s live AQI map turns about 40 state monitors into one number per city, hourly. Every county meets federal standards, so risk is episodic: hot stagnant afternoons and prescribed-burn smoke.
Key Takeaways
- Georgia EPD runs about 40 monitoring sites in 30 counties, feeding AirNow.
- No Georgia county is currently unattainable. Metro Atlanta moved to maintenance in November 2022.
- Ozone season runs March 1 through October 31. EPD forecasts only Atlanta, Macon and Columbus.
- The EPA tightened the PM2.5 AQI scale in May 2024, so identical air scores higher. Prescribed burning, not wildfire, is Georgia’s largest smoke source.
Where Georgia’s Live AQI Readings Come From
Every Georgia AQI map traces to one origin: EPD’s Ambient Monitoring Program, roughly 40 sites in 30 counties, feeding AirNow.
Filterbuy’s Georgia page renders the state as a ranked city list. Commercial maps interpolate between stations, so a city with no nearby monitor gets an estimate. On its live Georgia air monitoring map, EPD states readings are published before quality assurance validation. Treat the live number as an operational signal, not a measurement.
How to Read Today’s AQI Number for Your Georgia City
The AQI runs 0 to 500 across six categories. A value of 100 roughly matches the national standard for the hour’s highest pollutant.
Concentrations below reflect breakpoints in force since May 6, 2024. The EPA explainer on the six AQI categories and what each means for health is the reference.
| AQI | Category | PM2.5, 24-hr (ug/m3) | What it means in Georgia |
|---|---|---|---|
| 0-50 | Good | 0.0 – 9.0 | Normal activity. |
| 51-100 | Moderate | 9.1 – 35.4 | Fine for most. |
| 101-150 | Unhealthy for Sensitive Groups | 35.5 – 55.4 | Sensitive groups ease off. |
| 151-200 | Unhealthy | 55.5 – 125.4 | Everyone limits exertion. |
| 201-300 | Very Unhealthy | 125.5 – 225.4 | Move indoors. Add filtration. |
| 301+ | Hazardous | 225.5 and above | Stay indoors. |

The live number and the daily number are calculated differently
Real-time AQI uses a NowCast weighted to recent hours, so it tracks smoke arriving in an afternoon. The daily value uses the 24-hour average, so the two will not match. Our walkthrough of how to read the AirNow AQI map for San Diego County covers a different pollutant mix.
Why Georgia’s AQI Reads Higher Than It Did a Few Years Ago
On May 6, 2024 the EPA lowered the annual PM2.5 standard from 12.0 to 9.0 ug/m3 and rescaled the AQI. A concentration scoring 45 before now scores near 60, without the air changing.
The EPA reconsideration of the particulate matter standards set the AQI value of 50 at 9.0 ug/m3, and EPD said smog alerts would trigger at lower levels. If you think Georgia conditions are worsening, some of that shift is the ruler.
Georgia Smog and Ozone: a Seasonal Problem, Not a Year-Round One
Ground-level ozone drives most Georgia smog alerts and is seasonal. The state monitors it March 1 through October 31 and forecasts it April 1 through October 31. Outside that, readings are almost always fine particles.
Ozone forms when nitrogen oxides react with volatile organic compounds in sunlight, so it builds through the day rather than peaking with morning traffic. Dates sit on EPD’s Atlanta air quality forecast page. Statewide nitrogen oxide emissions fell 68 percent over three decades.
Fine Particles in Georgia: Prescribed Burns, Drifting Smoke and Winter Air
Georgia’s fine-particle story is not a wildfire story. More than a million acres burn here each year through prescribed fire, managed by EPD and the Forestry Commission.
The best tool here is no air quality guide. EPD’s page on how wildfires and prescribed fire affect Georgia air quality is topped by the Forestry Commission burn viewer. Our research into how state controlled-burn programs are managed and what they mean for home filtration applies to any burn-season state.
Drifting smoke matters too: EPD points to November 2016, when Southeast wildfires raised PM2.5 hundreds of miles away. Winter adds inversions, so a still January morning can read high with no fire nearby.
The Georgia Air Quality Year, Season by Season
Georgia’s ozone season, forecasting season and burn bans run on different dates. Overlaid they produce a predictable year that no agency publishes as one view.
| Period | Main driver | Rules in effect | What to watch for |
|---|---|---|---|
| Jan – Feb | Fine particles | Non-summer limits, 27 counties. | Inversions trap particles. |
| Mar – Apr | Both | Ozone monitoring opens Mar 1. | First hot afternoons overlap burn activity. |
| May – Sep | Ozone | Summer Burn Ban, 54 counties. | Hot afternoons. Mornings cleaner. |
| Oct | Transition | Ozone season closes Oct 31. | Late ozone as burning resumes. |
| Nov – Dec | Fine particles | Non-summer burn restrictions in 27 counties. | Burn activity, early inversions. |

What to Do If Your City Is Not One of the Three Forecast Metros
EPD forecasts next-day air quality for Atlanta, Macon and Columbus only. Savannah, Augusta, Athens, Rome and Valdosta are monitored but not forecast.
- Work from the nearest monitor, not your city label. A ranked list, like Filterbuy’s for Georgia, shows whether one city is elevated or the state.
- Borrow the ozone forecast. Ozone forms regionally, so an Atlanta forecast is a fair proxy, but not for smoke, which is local.
- For smoke, use the burn permit map. Where there is no forecast, the calendar above is the forecast.
Does Metro Atlanta Actually Meet Federal Air Quality Standards?
Yes. As of the EPA Green Book update of August 31, 2026, no Georgia county carries a nonattainment designation. Metro Atlanta holds maintenance status.
We went county by county rather than taking ranking coverage at face value, and every Georgia entry in the EPA Green Book record for Georgia is a revoked standard or a maintenance designation, with redesignation effective November 16, 2022. In its statement on the redesignation, EPD noted it was the first time Georgia met every standard statewide.
Attainment is a multi-year judgment, not a statement about this afternoon. An area can meet the annual standard and still record orange days, which is why a live map earns its place.
What to Do Indoors When the Georgia AQI Climbs
Once the AQI passes 100, indoor air is what you control. Stop outdoor air coming in, keep it moving through a filter, add no particles.
- Close windows and exterior doors while the reading stays above 100.
- Set the fan to On rather than Auto, switch to recirculate, and close any fresh-air intake.
- Fit the highest-efficiency filter your system accepts. During smoky periods the EPA recommends an HVAC filter rated MERV 13 or higher, if replaced frequently.
- Replace it when the media looks dark. Skip candles, wood fires and sprays.
A filter above what your system supports restricts airflow. See how MERV 13 and HEPA filtration actually differ in practice and how airborne dust circulates indoors.
Filterbuy, a U.S. air filter manufacturer in Talladega, Alabama, produces pleated HVAC filters in MERV 8, 11 and 13 and publishes free state and city air quality pages. Its Georgia page is listed first under Essential Resources. On ozone days no filter helps: the fix is scheduling.
“Georgia meets every federal air standard in every county, so a live AQI map is not there to frighten you. It is there to tell you which six afternoons a year to move the run to morning, and to warn you that on the days ozone is driving that number, no filter on the market will help.”

Final Thought and Opinion
Georgia meets every federal standard, in every county. That changes what a live AQI map is for. What follows is my read on it.
1. The Map Is a Scheduling Tool, Not an Alarm
My position: A live AQI map here is for planning your day, not for fear. It detects roughly six inconvenient afternoons a year.
2. Georgia’s Smoke Is More Predictable Than Most of the Country’s
My position: Georgia’s smoke is permitted burn by burn, so the burn viewer beats the AQI map on a smoky day: it says where it came from.
3. No Filter Removes Ozone, and the HVAC Industry Is Vague About That
My position: The opinion my own industry will dislike: filtration works on particles and does nothing for ozone, which drives most Georgia smog alerts.
Frequently Asked Questions
What is the air quality index in Georgia today?
It depends where and when. Georgia EPD publishes hourly readings at airgeorgia.org and forecasts three metros.
Which Georgia cities have the worst air quality?
The ranking shifts daily with weather and smoke, so an annual list is a poor guide. Filterbuy’s Georgia page ranks cities live.
Can an HVAC filter help with smog and smoke?
It helps with particles. A higher-MERV filter captures PM2.5 from smoke, but none removes ozone, a gas.
