Today's air quality for the majority of Alameda County is within the 100-150 range, which is Unhealthy for Sensitive Groups. Air quality tomorrow, Friday, Saturday and Sunday are expected to worsen and be designated Unhealthy. Active children and adults, and people with respiratory disease, such as asthma, should limit prolonged outdoor exertion.  Residents should protect themselves from the impacts of heavy smoke. If you  see or smell smoke in the immediate area, avoid outdoor activity, including exercise.

Bay Area residents impacted by wildfire smoke are advised to:

  • Stay aware of health warnings related to smoke.
  • Close windows and doors.
  • Set air conditioning units and car vent systems on re-circulate to avoid drawing in outside air./li>
  • Limit outdoor activities to avoid unnecessary exposure to smoke.
  • Parents and school/day care administrators should check air quality readings before allowing children to engage in outdoor sports and recreational activities while air quality is unhealthy.
