The Air District is extending the Spare the Air Alert for smog through Thursday, September 8. Air quality is forecast to be unhealthy. Continued high pressure over the region will result in clear skies, light winds, and hot temperatures across the Bay Area. These conditions, combined with motor vehicle exhaust, will produce unhealthy ozone levels.

Spare the Air Status

Spare the Air Alerts are issued when ozone pollution is forecast to reach unhealthy levels. Ozone can cause throat irritation, congestion, and chest pain. It can trigger asthma, inflame the lining of the lungs, and worsen bronchitis and emphysema. Long-term exposure can reduce lung function. Ozone pollution is particularly harmful for young children, seniors, and those with respiratory and heart conditions. When a Spare the Air Alert is issued, outdoor exercise should be undertaken only in the early morning hours when ozone concentrations are lower.

To find out when a Spare the Air Alert is in effect, residents can register for email AirAlerts at, call 1(800) HELP-AIR, download the Spare the Air App or connect with Spare the Air on Facebook or Twitter.
