Almost every county in Washington is F for particle pollution. Meanwhile, New Jersey doesn’t have a county below B for particle pollution. The rest of the west coast is the same. Is there something coming in from the Pacific Ocean to be causing this?
It's the smoke from the annual forest fires of late summer and early fall throughout the West Coast. That smoke makes for really high individual 24-hour readings, plus ends up skewing the annual averages as well.
