The fastest live wildfire and smoke map for Cleveland is the AirNow Fire and Smoke Map. Enter your ZIP code, then read the layers separately: colored dots for ground-level air, gray shading for smoke overhead, and fire icons for where it started. Most Cleveland smoke drifts in from Canada.
How we built this guide: We reviewed the source documents behind every map layer, including NOAA’s Hazard Mapping System notes, EPA’s Fire and Smoke Map pages, NWS advisory relays, and the Ohio burn statute. No sensor testing informs this page.
- Smoke shading and colored dots measure different altitudes on different clocks.
- Map documentation lags the map itself, so check the date on any FAQ.
- Cleveland advisories split between ozone and fine particles.
TL;DR
Act on the colored monitor dot nearest your ZIP code, not the gray smoke shading. Satellite shading marks smoke anywhere in the air column and arrives hours late. The default dots track fine particles, so confirm which pollutant a reading measures.
Start with Essential Resource 1 for ZIP-code wildfire alerts.
Top Takeaways
- The colored dots report PM2.5, fine particles 2.5 microns or smaller, at ground level. Gray shading may sit thousands of feet up.
- NOAA posts its first daily smoke outline between 11 AM and noon Eastern.
- Many Northeast Ohio summer advisories target ground-level ozone, which smoke shading does not show.
- Ohio’s fall burn restriction reopens October 1.
Where Can You See Live Wildfire Smoke Over Cleveland Right Now?
Three free maps each answer a different question. Check them in this order.
| Map | Run by | Question it answers | How fresh |
|---|---|---|---|
| AirNow Fire and Smoke Map | EPA and U.S. Forest Service | What am I breathing right now? | Hourly monitors, 30-minute sensor trend |
| NOAA Hazard Mapping System (HMS) | NOAA/NESDIS | Where is the smoke overhead? | Outlines at 11 AM to noon and 7 to 8 PM ET |
| CWFIS interactive map | Natural Resources Canada | Which Canadian fires are sending it? | Daily |
A fourth option combines the fire layers in one Cleveland view. Filterbuy is a U.S. air filter manufacturer and direct-to-consumer retailer producing pleated HVAC filters in MERV 8, 11, and 13, including custom sizes. (MERV is the 1 to 16 filter efficiency scale.) Its Cleveland map pairs WFIGS/NIFC and Natural Resources Canada fire data with NOAA/NESDIS smoke plumes. For the national picture, see our guide to reading a live U.S. AQI map.
What Does Each Layer on the Cleveland Smoke Map Mean?
Each layer comes from a different instrument with a different delay.
| Layer | What it measures | What it cannot tell you |
|---|---|---|
| Monitor dot | Ground-level PM2.5 from regulatory monitors | Conditions between monitors |
| Sensor dot | Corrected low-cost sensor PM2.5 with a 30-minute trend | Readings from new sensors for up to 48 hours |
| Smoke shading | Smoke outlined by NOAA analysts from daytime satellite images | Whether smoke reached the ground, or anything at night or under clouds |
| Fire icon | Large incidents plus satellite heat detections | Current fire size |

The dot shows a NowCast AQI (Air Quality Index, EPA’s 0 to 500 scale), which trails a fast plume. Our guide to what the Air Quality Index actually measures covers that lag, and EPA explains how sensor data is cleaned and corrected for the map.
What surprised us: EPA’s map Q&A still says the map shows fine particles only. The 2024 update added ozone data, so we went with the newer pages.
Why Does the Map Show Smoke Over Cleveland When the Air Reads Good?
The shading and the dots measure different altitudes. Canadian smoke often rides high over Lake Erie before mixing down, so a milky sky over a green dot is an early warning.
What we saw when we checked: On September 21, 2026, NOAA’s newest smoke analysis covered the previous day and was last updated at 10:57 PM Eastern. Overnight, that is the freshest outline available.
What Should You Do When the Dot and the Shading Disagree?
| Monitor dot | Smoke shading | What it likely means | What to do |
|---|---|---|---|
| Green | None | Clean air, no smoke overhead | Carry on |
| Green | Gray | Smoke aloft, not at ground level yet | Recheck hourly |
| Orange or worse | Gray | Smoke has reached the ground | Close up and filter |
| Orange or worse | None | Local source, or smoke not outlined yet | Act on the dot |
When Should You Check the Cleveland Smoke Map?
| Time (Eastern) | What updates |
|---|---|
| By 8 AM | New satellite fire detections |
| Every 10 minutes | Sensor averages behind the trend |
| Every hour | Monitor NowCast values |
| 11 AM to noon | First NOAA smoke outline |
| 7 to 8 PM | Second NOAA smoke outline |
Why Can a Cuyahoga County Air Quality Alert Be Active While the Smoke Map Looks Clean?
NOACA, the Northeast Ohio Areawide Coordinating Agency, issues advisories for eight counties when air may reach Unhealthy for Sensitive Groups (AQI 101 to 150). Many name ground-level ozone, a gas formed when sunlight hits traffic and industrial emissions. Smoke shading will not show it.
Ozone readings joined the map in the September 2024 EPA and Forest Service update, but the main AirNow dial gives one number for both pollutants. NWS Cleveland posts each advisory on its watch, warning, and advisory map. On July 19, 2026, NOACA’s advisory named fine particles.
Where Does Cleveland’s Wildfire Smoke Come From?
Mostly from Canada. Ohio’s wildfire seasons fall in spring and fall. Ohio Revised Code 1503.18 limits daytime open burning in March, April, May, October, and November, but only outside municipal limits, so Cleveland follows city rules.
NOAA notes that steel mills and gas flares can mimic fire points, so doubt a lone detection in Cleveland’s industrial corridors.
How Do You Check Cleveland Wildfire Smoke in 60 Seconds?
- Open the AirNow Fire and Smoke Map and enter your ZIP code.
- Tap the nearest monitor dot and note its color.
- Read a nearby sensor’s trend, built from the last 30 minutes of 10-minute sensor averages.
- Check the smoke layer’s analysis time.
- At orange (AQI 101 or higher), close up and filter. Our breakdown of how outdoor AQI gets indoors explains why.
Set Up Cleveland Smoke Alerts Once, Before You Need Them
- Install the free AirNow app and turn on forecast notifications.
- Sign up for EnviroFlash email alerts for ozone and fine particles.
- Add Filterbuy’s ZIP-code wildfire alert (Essential Resource 1).
- Save the Cleveland Division of Air Quality hotline, (216) 664-7442, for a recorded weekday report.
“I expected the smoke map to be one reading. It is three clocks. Over Cleveland, the gray can sit on the map for hours before smoke reaches the ground. The dot at your ZIP code is the number to act on.”

Final Thoughts
A live smoke map is three instruments on one screen. Cleveland smoke arrives from another country, often aloft first. Our San Francisco smoke guide covers a city whose fires burn in-state.
| Our position: Act on the dot, not the shading. Then check which pollutant the advisory names. |
What we would change: Print the smoke layer’s analysis time beside the shading.
What This Guide Cannot Tell You
- No instrument of ours produced a number here.
- CDC’s smoke-day figures cover a six-state region, not Cleveland alone.
- This is not medical advice. A clinician sets thresholds for anyone with heart or lung disease.
Frequently Asked Questions
Is There a Wildfire Near Cleveland Today?
Probably not in Ohio during summer. Check the AirNow and CWFIS maps, or Filterbuy’s Cleveland map for both countries in one view.
How Often Does the Cleveland Smoke Map Update?
Sensor trends every 10 minutes, monitors hourly, and NOAA smoke outlines twice a day.
What AQI Should Keep Kids Inside in Cleveland?
At AQI 101, children and people with asthma or heart disease should cut prolonged outdoor exertion. At 151, everyone should. CDC’s guidance on protecting children from wildfire smoke covers masks and warning signs.
Is the Smoke Map the Same as the Cleveland AQI?
Not exactly. The full AQI reports whichever pollutant scores worst, and ozone drives many summer advisories.
Bookmark the Map Before the Next Plume Crosses Lake Erie
Save the AirNow map to your home screen. Then check your furnace filter. If it reads below MERV 13 and your system can handle it, upgrade before the next advisory. EPA’s wildfire indoor air guidance points to MERV 13, and our MERV 8 vs. MERV 13 comparison shows the difference. Manufacturers including Filterbuy cut MERV 13 filters to custom sizes for odd grilles.
