What to Do if You’re Riding in Smoke From Wildfires
Close your windows and get inside or into your vehicle with vents sealed, especially when AQI hits 100 or PM2.5 rises above 55 µg/m³. Use a NIOSH-approved N95 mask if outside-it blocks 95% of harmful particles when fitted snugly. Avoid biking through smoke; it strains your lungs and reduces endurance. Recirculate air in your car, upgrade home HVAC to MERV 13, and monitor for coughing or chest pain. Real riders report clearer breathing with HEPA filters and prompt sheltering-there’s more to optimize your safety when smoke hits.

Notable Insights
- Leave smoky areas quickly and seek shelter indoors or in a vehicle with windows and vents closed.
- Use the recirculate mode on your car’s AC to reduce wildfire smoke from entering the cabin.
- Check AirNow.gov for real-time AQI and avoid riding when levels exceed 100, especially above 150.
- Wear a properly fitted NIOSH-approved N95 respirator to protect against harmful PM2.5 particles.
- Monitor for symptoms like coughing or shortness of breath and seek medical help if they persist.
Get to Clean Air Immediately
While you’re out on a ride and the air suddenly turns hazy with smoke, your first move is to get to clean air fast-every minute in poor air quality adds strain, especially if you’re pedaling hard on a trail or exposed to open roads. Wildfire smoke compromises your lung function and fresh air intake, so reduce your smoke exposure by leaving the area immediately. Seek shelter indoors or in your car with windows and vents closed. When driving, use recirculate mode on your AC to limit smoke infiltration. Check the air quality using the AQI; aim for values below 50. If you’re near active fire zones, outdoor air quality can deteriorate rapidly. Children, older adults, and those with heart or lung conditions must act quickly. Don’t rely on cloth masks-they won’t help. NIOSH-approved N95 or N100 respirators offer real protection, but only if they fit snugly.
Check Wildfire Smoke Levels at AirNow.gov
How do you know when it’s safe to ride? You check wildfire smoke levels at airnow.gov. This site gives you real-time wildfire smoke levels using the Air Quality Index (AQI), which tracks particle pollution, including fine particles that harm your lungs. When the AQI rises above 100, sensitive groups should limit outdoor activity, and levels over 150 are unhealthy for everyone. The Smoke Map shows current fire locations, smoke plumes, and hourly forecasts so you can plan rides away from unhealthy concentrations. AirNow pulls data from local monitoring stations, satellites, and models, giving you accurate, location-specific updates. You can even sign up for EnviroFlash alerts to get email notices when smoke worsens. Always follow advice from local officials and use the AQI to decide if you should ride or wait-your health depends on it.
Wear an N95 Mask Outside

| Tightly fitted seal | Maximizes filtration efficiency |
| Replace N95 masks regularly | Maintains performance in wildfire smoke |
Keep Smoke Out of Your Home
You’ve already taken steps to protect yourself outside with an N95 mask, but your home needs just as much attention when wildfire smoke rolls in. To keep smoke from seeping in, close windows and doors tight. Use a portable air cleaner with a HEPA filter in rooms you use most-run it on high for best results. If you have central HVAC, upgrade the filter to MERV 13 or higher and set the system to recirculate mode to close the outdoor intake. This boosts indoor air quality fast. Create a clean room where you spend the most time, keeping it sealed and free from pollution sources. Avoid breathing smoke by not using candles, gas stoves, or single-hose AC units. Every step helps you avoid breathing smoke and stay safe.
Monitor for Smoke-Related Health Symptoms
Why might you feel short of breath even after leaving smoky trails behind? Wildfire smoke contains fine particles and carbon monoxide that can linger in your system, impairing oxygen delivery and triggering symptoms like shortness of breath, coughing, or chest pain-even 24 to 48 hours post-exposure. If you have chronic heart conditions, heart disease, or lung diseases like asthma or COPD, pay extra attention to worsening symptoms. Children, older adults, and pregnant people should also stay alert. Persistent cough, painful breathing, dizziness, or confusion could mean internal damage, even without obvious signs. Don’t wait-seek medical attention if symptoms arise. Healthcare providers can assess oxygen levels and lung function, especially important after heavy exposure. Even if you feel fine, consider a medical evaluation. Early detection helps prevent long-term harm, keeping you trail-ready and safe.
Evacuate Early If Wildfire Smoke Worsens
When smoke thickens and visibility drops below five miles, it’s time to go-fast. If you’re on a trail or bike route and see dense smoke rolling in, don’t wait-evacuate early. During Fire Season, exposure to smoke can spike rapidly, degrading air quality to hazardous levels (AQI above 300). Trust local emergency alerts and local news over assumptions; use AirNow’s Fire and Smoke Map to track threats in real time. Even with mechanical ventilation in your gear or shelter, prolonged exposure to smoke harms health. An N95 respirator helps, but it’s no substitute for clear air. Have your evacuation plan ready-packed emergency kit, extra meds, and multiple escape routes. When flames or a strong burn odor hit your senses, Evacuation isn’t optional. Act before roads clog and comms fail. Your safety depends on moving fast, not waiting.
On a final note
If you’re riding in wildfire smoke, get to clean air fast-check AirNow.gov for real-time AQI levels, and don’t ride if it’s over 150. Wear an N95 mask outdoors; it filters 95% of fine particles. Keep windows closed, use a HEPA air purifier at home. Watch for coughing, wheezing, or shortness of breath. Evacuate early if smoke thickens. Protect your lungs, not just your ride stats.
