What's in Oldsmar's Air Right Now
PM2.5 (fine particles): 22 µg/m³. Readings between 12 and 35 µg/m³ rate Moderate. Sensitive lungs may notice on longer outings. These particles come from exhaust and smoke and are small enough to reach deep into your lungs.
PM10 (coarse dust): 59 µg/m³. Readings between 54 and 154 µg/m³ rate Moderate, usually from wind stirring up dust. Dust and pollen fragments ride in this size range and irritate your nose and throat.
Ozone: 38 µg/m³. Ozone forms when sunlight cooks car exhaust, so hot afternoons read worst, usually between 2 PM and 7 PM. Mornings stay cleanest.
Nitrogen dioxide: 1.5 µg/m³. NO2 comes almost entirely from traffic and feeds afternoon ozone. Readings run highest near busy roads during the morning and evening commutes.
Is It Safe to Go Outside in Oldsmar Today?
Yes, for most people. Healthy adults and kids can keep their normal routine on a Moderate day in Oldsmar.
If ozone or smoke usually bothers you, plan harder outdoor effort for the morning, before ozone builds. Asthma? Carry your rescue inhaler.
Later This Week
Rain is likely Friday (64% chance). A steady shower scrubs particles out of the air, so the hours right after rain usually read cleanest.
Air Quality and Pollen Are Two Different Numbers
The air quality index tracks pollution: ozone, dust, smoke, and exhaust. Pollen isn't part of the score, so a Good air day in Oldsmar can still be a rough allergy day.
Right now the biggest pollen load in Oldsmar is grass pollen, rated Very High. If your eyes itch while the air reads clean, pollen is the likely culprit.
