Air pollution spikes dramatically in July

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 Resource 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.

What is the cause and effect relationship behind this pattern? What man-made event is causing this impact on the environment? What are some ways we can reduce this air pollution?
