Spare The Air Season is Here

Spare The Air Alerts are issued when ozone pollution is forecast to reach un­healthy levels. Ground-level ozone is formed when exhaust particles from vehicles react with the sun’s ultraviolet rays. High levels occur most often during the summer months, when days are hot and there’s no relief from cooling offshore breezes. In addition, a wildfire smoke advisory may be issued when smoke from wildfires contributes to poor air quality. Although air pollution can cause health problems for everyone, it is especially harmful for young children, pregnant women, seniors, and those with respiratory and heart conditions. High levels of air pollution can force the respiratory system to work harder to provide oxygen.

The Sacramento Metropolitan Air Quality Management District will issue a Spare The Air Alert when the Air Quality Index (AQI) for ozone is forecast to reach 126 or above. To help protect yourself, your family and the community, follow these simple tips:

  • Download the free Sacramento Region Air Quality app to receive the daily air quality forecast, Spare The Air alerts, and wildfire smoke advisories.
  • Limit your time outside to reduce exposure to air pollution on a Spare The Air day. Exercise or play outdoors in the morning or late evening when air quality is typically better.
  • Drive less when you hear a Sacramento region Spare The Air alert.
