The nasty air has been blowing through periodically all summer. Not sure you can really predict it. The prevailing winds get a boost from Lake Michigan so the filth moved off to the south and east pretty quickly this week. Hopefully we get another few weeks of clear air.

The whole west coast is nice and all the places you mentioned have lovely spots and a lot of tourist services. It will be pretty busy this time of year and it’s always a bit expensive but heading up to traverse and getting out to sleeping bear is very worth the effort. Especially if you like to hike.
