The smog is not usually bad here but we have had forest fires burning for over a month now and the air has been very smokey (20% of the state has now been burnt). There have been a few days that I have left the bike at home as I haven't fancied riding in 100 degrees through air I can taste. Thankfully it is raining today (it hasn't rained for a few weeks) and it will help to clear the air and to put out the fires.
