I have been riding opportunistically, dodging both heat and smoke.
Early on, when the August Lightning Complex fires were totally uncontained, we had some days when the air was just frightening, then it would blow completely out the next day and it would be clear as you could wish for - single digit AQI's on PurpleAir. Since I'm Working From Home 3 out of 5 days, I have some flexibility. Initially, I'd only ride if it was 'green', but over time I modified that to "<70 the whole trip", knowing it might change over a 2 hour ride.
Yesterday, it was too DARK to ride, even though the AQI said the air was okay. I mean, in San Mateo where I live there were times when it was as dark as half an hour after dusk! Today, it's light enough to ride but the AQI is >100.(LRAPA Converted). So, I'm gonna ride the trainer today.
