When is a Spare the Air Alert issued?

Typically, a Spare the Air Alert is issued during peak ozone months, May–October, when ground-level ozone (smog) is forecast to meet or exceed 126 on the Air Quality Index (AQI). However, we have seen alerts at other times of the year or for other reasons, when the air quality is poor and the AQI exceeds recommended levels.
