The Air Quality Index in my town is currently 260 (very unhealthy) due to a surge in wildfires in western Canada and the northwest US. There are additional smaller fires not shown on this map at this zoom level.
From the interactive map it looks like the worst air in the world right now.
We had 999 (scale used didn’t go any higher) during the Australian fires a few years back. Going to need a new air quality measurement system soon. :/
Bet you could chew the air at that point
Could feel it too. Anything above 100 is already unpleasant. It got so bad it was like a gritty orange fog, and the smell got into everything. Couldn’t see ten meters on the worst days. Thankfully we had air filter units already for hayfever season.
