Right now, several parts of the state of California are on fire. This isn’t the usual early-fall fire season where dry offshore winds fan the flames—that’s yet to come, oh boy! This is a weirder set of fires started by lightning from a rare set of thunderstorms that passed through a few weeks ago.
In any event, when there are fires burning within a few hundred miles of where you live, the air quality can be really bad and highly variable. Just yesterday, we awoke to clean air. Then the wind shifted and the Air Quality Index (AQI) went rapidly from green to red. It was hazy and ugly outside, and smelled like a barbecue. A couple of hours later, the air was back in healthy territory and I went for a run.
