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.
Yeah, the PNW has been a horror show the last several summers. In Eugene, at the tail end of the Willamette Valley, 260 is a bad day but in August not bad enough to be brought up in small talk. We were in the 500’s last Tuesday then last Saturday the winds shifted and we has a whole day of clear air with AQI in the teens. I was exhausted from trying to get as mush outside stuff done as possible.
It’s been normal for the last 4 or 5 years and nearly unheard of before that.
I’ve experienced 450 in Chiang Mai, Thailand and you could taste the air. It was not pleasant at all.
Saw 600 in Shanghai a few years ago. It was horrific. Fortunately the Chinese government has made quite a bit of progress in improving air quality in the last decade so such terrible pollution isn’t nearly as common today as it used to be.
Yeah I was pretty impressed by how awful the air was in Beijing some years ago. Glad to hear it’s getting better.
In the 2019 mega-fires, Sydney hit a max of over 2,500.
It can get a lot worse yet…
It’s been really hampering my camping efforts the last few years. It’s bullshit.
It was bad enough that I gave in and moved away. The smoke is brutal on my asthma.
