I'm still very new to hosting (only on my 2nd guests). Our area is having fires about an hour or so away from my place. So far, the worst of the smoke has been in the morning, and it clears out by afternoon. I am completely booked the rest of the month, but the smoke situation is stressing me out a bit and making me wonder what my responsibilities as a host are - do I let guests know that we are experiencing times of heavy smoke? Nearly all of my guests are from the other side of the state, so I've got to think they know about the fires on this side, with it being in the local and state news outlets, but being new and needing to get those first good reviews is obviously important.
Just to clarify, my Airbnb is in no way in danger of the fires, and there are places as close as 20 minutes away to escape the smoke until it clears. I also have an air purifier for guests.
