Air Quality Monitoring

Climate Change is real and affects health in many ways. If you see or smell smoke in the immediate area, limit or avoid outdoor activity, including exercise. This particularly applies to children and older adults, people with breathing or heart issues, such as asthma, and pregnant individuals.

Check San Leandro's current air quality.

Air Quality index guidance

If air quality is forecast to be unhealthy, a Spare the Air Alert will be called by the Bay Area Air Quality Management District. The alert will be in effect the entire next day, for a full 24 hours. See the figure for guidance from Alameda County Public Health Department on air quality index and corresponding recommendations.


Bay Area residents impacted by wildfire smoke are advised by the Alameda County Public Health Department to:

  • Stay indoors with windows and doors closed, where air quality is better.
  • Keep indoor air cool or visit an air-cooling center.
  • Set home and car ventilation systems on re-circulate to prevent drawing in outside air.
  • Stay hydrated by drinking water.
  • Limit or avoid outdoor recreational and sports activities.
  • Use an air filter, especially if there are household members with heart disease, asthma or other respiratory conditions, or elderly persons and children.
  • Avoid using wood-burning stoves or fireplaces, lawn mowing, leaf blowing, burning candles and incense, barbecuing, smoking.
  • If possible, leave the affected area for the duration of a heavy smoke event.
