When air quality in your area reaches unhealthy levels, we'll send you a quick alert, along with expert tips on how to reduce your exposure.
The Air Quality Index (AQI) measures how polluted the air is and how it may affect your health.
0–50 (Good): Air quality is satisfactory.
51–100 (Moderate): Acceptable, but some pollutants may pose minor concerns.
101–150 (Unhealthy for Sensitive Groups)
151–200 (Unhealthy)
201–300 (Very Unhealthy)
301+ (Hazardous)
Still okay for most, but if you have asthma or allergies, take it easy and avoid long outdoor workouts.

You step outside in Tampa on a July morning, the sky looks a little milky, the air feels heavier than the day before, and you catch yourself wondering whether it's safe to let the kids play in the yard. The live air quality index map on this page answers that question in real time, pulling current readings for Tampa and the surrounding Hillsborough County area so you can decide what to do before you head out the door.
Air quality in Tampa shifts through the day. Ground-level ozone climbs on hot, sunny afternoons, fine particle pollution drifts in with traffic and summer dust, and a calm, humid morning can read very differently by three in the afternoon. Checking the current number takes a few seconds and tells you whether today is a good day for a run along Bayshore Boulevard or a better day to keep the windows shut and your system running.
At Filterbuy, we build and test air filters for a living, so we think constantly about what that outdoor number really means once you close the door and start breathing your indoor air.
Tampa's air quality usually falls in the Good to Moderate range on the AQI scale, which means most days carry little risk for healthy people. Ground-level ozone and fine particle pollution (PM2.5) are the two pollutants that push local readings highest, especially on hot afternoons and during summer Saharan dust events. Check the live map above for the current reading.
Top Takeaways
Ground-level ozone and fine particle pollution (PM2.5) drive most of Tampa's day-to-day AQI changes.
Ozone peaks on hot, sunny afternoons, and PM2.5 can spike during the Saharan dust plumes that reach Florida each summer.
An AQI at or below 50 is Good (green), 51 to 100 is Moderate (yellow), and 101 to 150 is Unhealthy for Sensitive Groups (orange).
Children, older adults, and people with asthma, COPD, or heart disease feel the effects of orange days first.
When outdoor AQI climbs, closing the windows and running your HVAC with a high-efficiency filter keeps your indoor air noticeably cleaner.
The map at the top of this page uses the U.S. Air Quality Index, the same color-coded scale that the EPA, the Florida Department of Environmental Protection, and the Environmental Protection Commission of Hillsborough County all report against. Each monitor shows a number and a color for the pollutant that's highest at that moment, so a green dot near downtown and an orange dot inland can both be accurate on the same afternoon.
Green (0 to 50) means the air is clean and you can do anything outdoors. Yellow (51 to 100) is acceptable for most people, though the unusually sensitive may notice mild symptoms. Orange (101 to 150) flags trouble for sensitive groups. Red (151 to 200) reaches everyone, and purple and maroon above that signal very unhealthy to hazardous conditions that Tampa rarely sees outside major smoke or dust episodes.
Tampa's warmth and strong sunshine cook vehicle and industrial emissions into ground-level ozone, which is why the worst readings usually land on hot, still afternoons. Fine particles come from traffic, coastal industry, and, in summer, dust from the Sahara that crosses the Atlantic and settles over Florida as a pale haze. Those dust events can raise PM2.5 for several days and turn the sky a milky gray that Tampa residents have learned to recognize. Here's something we notice from the filter side. During those dust weeks, filters in Florida homes load up faster than usual, a quiet sign of how much extra fine particulate is riding in on the air.
Here's what most air quality pages leave out. Florida sits on a peninsula, and the daily sea breeze keeps air moving in a way inland cities never get, which is the real reason Tampa's air is usually good. When a reading does climb, it's almost always a passing event rather than lingering smog, and two of those events run on a calendar you can plan around.
Late winter through spring is smoke season. Prescribed burns across the Southeast run heavily through late winter and spring, and Florida's own wildfire season peaks from April through June. On the wrong wind, that smoke drifts toward Tampa and lifts PM2.5 for a day or two.
Summer is dust season. Saharan dust crosses the Atlantic and settles over Florida from late June into mid-August, hazing the sky and raising fine-particle readings while hot, still afternoons keep ozone in the mix.
Neither one shows up on a thermometer, so the live map tells you more than the daily forecast does. We point Florida customers toward a fresh filter heading into spring and again before dust season, so the house is ready before the air turns.
If you or someone in your home has asthma, COPD, or heart disease, or if you're caring for young children or older parents, orange days deserve a plan. These groups can feel chest tightness, coughing, or shortness of breath at AQI levels that healthy adults barely notice. On those days, morning tends to be cleaner than late afternoon, so shifting a walk or a workout earlier often helps.
When the map turns yellow or orange, the practical move is to protect the air you breathe most, which is the air inside your home. Close the windows, run your HVAC on the fan setting to keep air circulating through the filter, and make sure that filter can actually catch fine particles. A Filterbuy MERV 13 filter traps a large share of the PM2.5 that ozone and dust days send your way, and it keeps working quietly in the background while you go about your day. We've tested our own filters against the fine particles that dust and smoke days throw off, and that's exactly why we steer people toward higher-efficiency media when the map turns orange.
On a hazy, high-dust week, the filter is the first thing I check. A clogged filter makes the whole system strain right when your home needs clean air the most, so I tell homeowners to keep a fresh one ready before the season starts.

After manufacturing filters for over a decade and serving more than two million households, we've seen the same pattern over and over. People watch the outdoor air, but the air they actually breathe most is inside their homes. When Tampa's AQI climbs, the smartest move is to protect your indoor air with a filter built to catch fine particles, keep it fresh, and let your system do the work.

Tampa gets a bad rap it doesn't fully deserve. For most of the year the air here is genuinely good, and the live map will show you a lot of green. What we care about at Filterbuy are the handful of days that break that pattern, the stagnant ozone afternoons in late summer and the dust weeks that roll in from across the Atlantic. Those are the days the AQI number stops being trivia and becomes a cue to act. After years of shipping filters into Florida homes, the pattern we trust most is that households treating a rising AQI as a prompt to refresh their filter breathe easier through dust season than the ones who only watch the number. Our honest take is that the outdoor reading earns its value only when it changes what you do indoors, because that's where you spend most of your hours and where a good filter earns its keep.
Bookmark this page and glance at the live map each morning through the summer ozone and dust season.
Sign up for advisory alerts from the Environmental Protection Commission of Hillsborough County so orange days reach you before you head out.
On yellow and orange days, move outdoor exercise to the morning and keep it lighter if you're in a sensitive group.
Close the windows and run your HVAC system with a fresh high-efficiency filter when the map climbs, and make sure you're choosing the right MERV rating for your system.
Check your filter monthly and swap it on schedule so it can keep pulling fine particles out of your indoor air.
A: Most days it isn't. Tampa usually reads Good to Moderate, and the live map at the top of this page shows the current number for your area. Watch for orange readings on hot afternoons and during summer dust events, when sensitive groups should limit time outdoors.
A: The live map reports current PM2.5 alongside ozone for each Tampa-area monitor. PM2.5 refers to fine particles 2.5 microns or smaller, and it tends to run higher during Saharan dust weeks and periods of heavy traffic or stagnant air.
A: Use the real-time map on this page, which pulls from official monitors. You can also check the EPA's AirNow site, the Florida DEP spatial map, or the Environmental Protection Commission of Hillsborough County, all linked in the resources above.
A: Two pollutants do most of the work. Ground-level ozone forms when heat and sunlight react with vehicle and industrial emissions, and fine particle pollution comes from traffic, coastal industry, and summer dust that travels from the Sahara to Florida.
A: Hot, sunny, still afternoons in late spring and summer bring the highest ozone, and the Saharan dust season, which peaks from late June into August, drives the biggest fine-particle spikes. Mornings are generally cleaner than afternoons.
A: Filterbuy makes MERV 8, 11, and 13 filters, and for most Tampa homes a MERV 13 is the sweet spot. It captures a large share of the fine particles that ozone and dust days send indoors. Higher isn't automatically better, so it helps to understand how MERV ratings work and confirm your system can handle the rating before you upgrade.
The outdoor number is only half the story. When Tampa's AQI climbs, the fastest way to breathe easier is to upgrade the filter that's already running in your home. Find your Filterbuy filter size and MERV options and get a fresh high-efficiency filter delivered, so your system is ready the next time the map turns orange.
