SAN FRANCISCO -- There is no Spare the Air Alert in effect at this time.
When an alert is in effect due to a heat wave, it can combine with vehicle exhaust to create unhealthy levels of smog. High levels of ozone, a major component of smog, can cause throat irritation, congestion and chest pain, trigger asthma and worsen other health issues. Ozone pollution is particularly harmful for young children, seniors and those with respiratory and heart conditions.
The air district encourages anyone planning to do strenuous activities to do so in the early morning hours when ozone concentrations are lower.
People can find out when a Spare the Air alert is in effect by registering for the alerts here, calling 1(800) HELP-AIR, downloading the Spare the Air smartphone app or connecting with Spare the Air on social media.

What are Spare the Air days?
Air quality in the Bay Area can be unhealthy at times throughout the year.
Spare the Air Alerts are called when ozone pollution is forecast to reach unhealthy levels. Ozone, or smog, can cause throat irritation, congestion, chest pain, trigger asthma, inflame the lining of the lungs and worsen bronchitis and emphysema. Long-term exposure to ozone can reduce lung function. Ozone pollution is particularly harmful to young children, seniors and those with respiratory and heart conditions.
When a Spare the Air Alert is called, outdoor exercise should be done only in the early morning hours when ozone concentrations are lower. Residents are encouraged to reduce air pollution every day by rethinking their commute and avoiding driving alone.
