Smoke from Canadian wildfires has once again drifted into New York, turning skies hazy and pushing air quality into unhealthy levels across much of the state
The New York State Department of Environmental Conservation has issued an Air Quality Health Advisory through midnight as elevated levels of fine particulate pollution are expected
Here’s what University of Rochester Medical Center pulmonologist Dr. Daniel Croft says New Yorkers should know
URMC doctor: ‘Unfortunately the wildfires are back’
“Unfortunately the wildfires are back,” said Dr. Daniel Croft, a pulmonologist with University of Rochester Medicine
Croft recalled the widespread wildfire smoke that blanketed western New York in 2023, when Air Quality Index (AQI) values climbed above 280, creating some of the worst air quality in the nation
During that event, doctors saw an increase in patients experiencing respiratory problems, particularly people with asthma, chronic lung disease and heart conditions
“When there’s poor air quality, it places additional stress on the lungs and cardiovascular system,” Croft said, noting that people with existing medical conditions are especially vulnerable
Heat makes poor air quality even more dangerous
Croft said this week’s heat is adding another layer of concern
Temperatures are expected to reach the upper 80s and low 90s across much of upstate New York, while New York City and parts of the lower Hudson Valley could see heat index values as high as 104 degrees
“High temperatures do worsen air pollutants,” Croft said. “It is particularly dangerous when there is high heat and high pollution.”
He acknowledged it’s frustrating to stay indoors during the short upstate summer but said it’s the safest choice while smoke levels remain elevated
“There are periods in summer where we need to slow down a bit and stay inside and just get past this,” he said
When will the smoke clear?
You may have already noticed hazy skies and an orange tint across parts of New York
National Weather Service meteorologist Heather Kenyon said the thickest smoke is expected across western New York on Wednesday and could linger into Thursday, July 16
The current Air Quality Health Advisory remains in effect through midnight, though officials could extend it if conditions do not improve
Check the AQI before heading outside
Croft recommends checking the Air Quality Index before spending extended time outdoors. Current conditions can be monitored at AirNow.gov and may change throughout the day
Around midday Wednesday, AQI readings included:
- Rochester: 142
- Albany: 138
- Ithaca: 127
- Elmira: 127
- Syracuse: 120
- Utica: 120
- Watertown: 117
- Poughkeepsie: 75
- New York City: 66
- Buffalo: 57
Who is most at risk?
Croft said the people most vulnerable to wildfire smoke include:
- Young children
- Older adults
- People with asthma or other lung diseases
- People with heart disease
How to protect yourself
- Check air quality before spending time outdoors.
- Limit prolonged or strenuous outdoor activity.
- Stay indoors with windows closed whenever possible.
- Use air conditioning or an air purifier if available.
- Stay well hydrated.
If you must be outdoors, he recommends wearing a well-fitting N95 or KN95 mask to reduce exposure to fine smoke particles
When to seek medical care
If you or someone else develops severe symptoms such as wheezing, chest pain or significant shortness of breath, Croft recommends moving to a clean, air-conditioned environment immediately and seeking medical attention
“Get the person into a clean environment, such as a home, library or other air-conditioned building,” he said. “If they’re having an extreme reaction, seek medical care right away.”
