The Spare the Air season normally begins on May 4. But the district said at that time, so few people were driving because of shelter in place that the air quality was actually really good.
Now as stay at home orders relax. More people are driving.
So Monday, the district issued its first alert of the year. It’s almost like things are getting back to normal.
Officials say that traffic is the Bay Area’s top contributor to air pollution. And the weather isn’t helping either.
Low wind, and a record breaking four-day heat wave will keep pollutants hanging around longer.
Residents are advised to consider alternatives to driving to keep smog levels low. And to avoid outdoor activities during the hottest part of the day, when air pollution levels and temperatures are at their highest.
