On July 5, 2018, San Diegans received cell phone notifications warning of poor air quality in San Diego. Similar warnings went out in 2017 and 2016 around the same time.
The graph above from the LA Times was generated using 2017 data from the California Air Resources Board. The graph shows a dramatic jump in air pollution around Los Angeles, and graphs using data collected from air monitoring stations closer to San Diego show a similar spike.
