This is the highest AQI reading I have ever seen - reached 750 near Apple in Cupertino yesterday.
California is burning up.
Anyone seen a reading that beat this?!

The highest AQI I personally saw on my watch was near 250 yesterday, but I have been avoiding the fire areas. Almost a million acres burned near the S.F. Bay Area last week, and most fire areas only about 10% contained. Basically out of control.
 
what's odd about this is that the EPA AQI scale is 0 - 500.
Worst I saw in SJ last week was 202
Good point. It seems that AQI, NowCast AQI, and PM 2.5 Concentration are similar, but not technically the same. EPA says that values more than 500 are "beyond the AQI."
These also are automated sensor readings, so perhaps not official AQI values.
