#ONStorm#ONwx 💨 No, Air Quality Is Not Expected to Significantly Improve in Southwestern Ontario Today
We wanted to address some misinformation circulating from a certain event taking place in the London area regarding today’s air quality.
The event is claiming that “conditions are improving” as justification for continuing with tonight’s outdoor activities. However, the current forecast and observations simply do not support that conclusion.
The only part of Southern Ontario expected to see meaningful improvement today is across portions of Central and Eastern Ontario, where shifting winds will gradually push the northern edge of the smoke plume southwestward.
That should allow air quality to slowly improve in areas such as Ottawa, Brockville, Kingston, Peterborough, Muskoka, North Bay and Sudbury. Notice London isn’t on that list.
Based on the latest data, Southwestern Ontario is expected to be one of the last areas to see the smoke clear. Thick ground-level smoke is expected to persist through this afternoon and evening, with poor air quality likely lingering into tonight. Some smoke may even remain into Friday across parts of Deep Southwestern Ontario.
It’s true that AQI values around London are lower than they were overnight, when some stations exceeded 500. However, readings dropped to around 150 this morning and have already begun climbing again, with many locations now back above 200. Those are normal fluctuations as the smoke shifts, but they should not be interpreted as conditions becoming safe.
A drop from an AQI of 500 to 200 is certainly an improvement, but an AQI of 200 is still considered very unhealthy. It’s similar to saying a Category 5 hurricane is no longer dangerous because it weakened to a Category 2. The risk has decreased, but it’s still a dangerous situation.
For prolonged outdoor activities to become reasonably safe, we would need to see AQI values fall much lower and remain there for an extended period. We’re simply not there yet.
Environment Canada continues to have an Orange Air Quality Warning in effect for the region. Their guidance specifically states:
“Limit time outdoors. Reschedule or cancel outdoor sports, activities and events.”
That’s about as clear as it gets.
We provide weather support for another outdoor event in the area, and based on the same forecast, we’ve recommended they move today’s and tomorrow’s activities indoors.
We hope organizers continue to monitor conditions closely and reconsider if necessary. When air quality reaches hazardous levels, protecting the health of attendees should always be the top priority.

@IWeatherON Thank you for this! I read 2 articles on LFP today. The first encouraging people to stay indoors due to the smoke. The second about Rock the Park proceeding as usual today. SMH 🤦♀️
@LFPress@RockTheParkLDN Shameful. The air quality is just as bad today. I just read a different LFP article advising against outdoor activities but in this article let’s tell people to go outside for a 6 hour concert. 🤦♀️
@Mikeggibbs Yes, just like Covid it seems to be more important to appear “normal” than to inform the public about the reality we are living in. Nothing will improve while society continues to live in denial. I’m angry and sad for the kids that are suffering the consequences of bad decisions.
Politicians,
PLEASE encourage your constituents to wear an N-95 mask today if they need to be out due to the air quality. The air today due to the 🔥 is no joke.
Thank you🙏🏿
@DrGorfinkel Yes! Every time I see these ads I’m reminded that bigger prisons won’t solve the underfunding of healthcare and education. It takes all my willpower not to throw something at the TV.
@wtflanksteak Because it’s a good deal and it might not be there next time plus you can always return it if you change your mind. At least that’s how it works for me at Costco 😂😭
@kadamssl@beansprouts_mom From the headline I thought somebody might mention that repeated Covid infections are actually bad. If everything is due to lockdowns then the cohort of kids born in 2022 starting school this fall should have no issues because they weren’t exposed to masks or lockdowns right? 🤬
I’m so sick of Doug Ford saying that the people of Ontario don’t care about this issue or any other issue that he deems unimportant. I’m starting to call his office every time he says it to remind him that I do care.
