Something that started as an upstate story just became a New York City story. Governor Hochul's office confirmed on July 15 that the state's wildfire smoke advisory, previously limited to three regions near the Great Lakes, has expanded to cover all of New York for today, July 16, including the city itself.
This is the third consecutive day the same event has forced a fresh government advisory. On July 14, an ozone advisory covered NYC Metro and Long Island. On July 15, that shifted to a PM2.5 advisory limited to three upstate and Great Lakes regions, Eastern Lake Ontario, Central New York, and Western New York. Today it is a full statewide "Unhealthy" advisory, with temporary spikes toward "Very Unhealthy," and for the first time it explicitly includes NYC Metro and Long Island again, the state's biggest and most searched market. The proximate cause is an active wildfire complex burning in western Ontario, Canada, compounded by a concurrent heat wave that has also pushed New York City to extend its own heat emergency plan into today.
The affected regions as of today are Long Island, New York City Metro, the Lower Hudson Valley, Central New York, Eastern Lake Ontario, and Western New York. This isn't isolated to New York either. Parallel advisories are active across New Jersey, Michigan, Wisconsin, and Rhode Island, with roughly 100 million Americans under some kind of air quality alert right now. New York's response includes distributing more than 100,000 N95 style masks to counties, and the MTA is handing out masks directly to commuters at Penn Station and Grand Central.
This is a time limited weather event, not a new scientific finding. The underlying health evidence on PM2.5 exposure was already well established before this week. The advisory is dated specifically for July 16 and will lapse once the smoke clears, and the scope has already changed three days running, so confirm current AQI at airnow.gov before you make plans rather than relying on this post alone.
If you're anywhere in the affected regions today, especially NYC Metro or Long Island, the basic playbook still applies. Limit strenuous outdoor activity, wear a properly fitted N95 style mask if you do need to be outside for a while, and run a real HEPA purifier indoors, since wildfire PM2.5 gets into buildings more easily than most people assume, even with windows closed. If you don't have a mask on hand, New York is distributing them free through county offices and at Penn Station and Grand Central.
As of July 16, 2026, yes. New York's statewide Air Quality Health Advisory now covers NYC Metro and Long Island for the first time this event, alongside the Lower Hudson Valley, Central New York, Eastern Lake Ontario, and Western New York. This is a fast changing situational advisory though, so confirm the current status at airnow.gov before you make plans, since the scope has shifted every day for three days running.
An active wildfire complex burning in western Ontario, Canada. The smoke is combining with a concurrent regional heat wave to push particle pollution into unhealthy territory across the Northeast and Midwest, with New York, New Jersey, Michigan, Wisconsin, and Rhode Island all issuing parallel advisories.
Limit time outdoors when the advisory is active, especially strenuous activity, and wear a properly fitted N95 style mask if you do need to be outside. Indoors, a real HEPA air purifier sized to your room makes the biggest difference, since PM2.5 from wildfire smoke gets indoors more easily than most people expect. New York is distributing free N95 masks through counties and at Penn Station and Grand Central if you need one on the spot.
