We can not avoid it any way we look at it.
But, the seasons change, and the weather changes, as well the atmosphere and the air quality to go with it.
The variation of the air quality in this city I live in can go from one extreme to the next. Now with it being fall time of year, the air quality is going to be great! I am so glad to be able to open up the windows in my house and not have to run my central heating and air conditioning system all the time. Running my central air conditioning all summer with as hot as it has been nearly made me go broke from the electric bills I was stuck having to pay. There was just no way around it. I had to run the central air conditioning system all the time. The temperatures here in the summer are always well over one hundred plus degrees. But, the upside of all this, is that the fall and winter months are really wonderful. That is why I live here. The air quality in the fall and winter here are possibly the best outdoor air quality in the entire united states of america! And the complete reverse is the truth in the summer time. The air quality then is some of the worst in this whole entire country! It is an even trade off the way I see it. Next summer, I may invest in a whole home air purification system to combat that really bad air quality. That means more money to spend, but I am willing to do it.
