What's in West Reno's Air Right Now
PM2.5 (fine particles): 583 µg/m³. Readings above 55 µg/m³ are high for everyone, not just sensitive groups. These particles come from exhaust and smoke and are small enough to reach deep into your lungs.
PM10 (coarse dust): 587 µg/m³. Readings this high usually mean blowing dust or smoke. Keep windows closed until it settles. Dust and pollen fragments ride in this size range and irritate your nose and throat.
Ozone: 13 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: 183.3 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 West Reno Today?
No. Air at this level in West Reno is a health emergency for everyone, not just sensitive groups.
Stay inside with windows closed and an air purifier running if you have one. Postpone anything outdoors that can wait a day.
One rule holds on any air day: trouble breathing means get medical care now.
Later This Week
Winds could reach 21 mph Wednesday. Gusty hours stir up dust and can bump particle readings until the wind settles.
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 West Reno can still be a rough allergy day.
Right now the biggest pollen load in West Reno is grass pollen, rated Moderate. If your eyes itch while the air reads clean, pollen is the likely culprit.
