Canadian Wildfire Smoke Blankets New York City and Long Island in July 2026

In July 2026, smoke from hundreds of Canadian wildfires traveled thousands of miles south into New York, creating one of the region’s most significant wildfire-smoke events since the historic episode of 2023. The combination of wildfire smoke, extreme heat and stagnant weather produced unusually poor air quality across New York City and Long Island.

July 14–15: Smoke Moves Into the Region

On Tuesday, July 14, New York City officials warned that smoke from wildfires burning in western Ontario, Canada, could reach the region. By Wednesday, July 15, the smoke had begun settling closer to the ground.

New York State expanded its Air Quality Health Advisory to include Long Island, Nassau and Suffolk Counties, as well as the New York City metropolitan area. The advisory warned of elevated levels of fine particulate matter, or PM2.5, from the Canadian fires.

Across Long Island, residents reported hazy skies, an orange-colored sun and the unmistakable smell of smoke. In places such as Westhampton Beach and Baiting Hollow, visibility was noticeably reduced and residents described the atmosphere as eerie.

July 16: The Smoke Reaches Its Worst Levels

Thursday, July 16, became the peak of the event. Smoke covered New York City and Long Island, producing yellow-orange skies and significantly reducing visibility.

In New York City, the regional Air Quality Index reached 289 — "Very Unhealthy" — at 10 p.m. Thursday, according to AirNow data cited by New York City Emergency Management. That was the second-worst wildfire-smoke event in the city's modern record, behind the June 2023 disaster when the AQI reached as high as 465. 

The smoke was particularly noticeable on Long Island. The East Hampton Star described the sky on July 16 as sepia-toned, with smoke covering the Island and multiple PM2.5 air-quality alerts in effect. 

The poor air quality also affected everyday life. Day camps moved activities indoors, outdoor workers shortened shifts, and residents were encouraged to limit strenuous activity outside. 

The problem was made worse by a heat wave. Temperatures were in the 90s, while the heat and atmospheric conditions helped keep pollutants close to the ground. New York City distributed free KN95 masks and kept cooling centers open. 

 July 17: Conditions Begin to Improve

On Friday, July 17, the smoke remained a problem across Long Island and the New York metropolitan area. Long Island again experienced unhealthy air-quality readings, prompting another health advisory. 

In New York City, air-quality readings improved to approximately 120, or Unhealthy for Sensitive Groups, by Friday afternoon. However, conditions temporarily worsened again Saturday morning, July 18, when readings reached 186 — Unhealthy. 

July 19: The Emergency Response Ends

Rain and changing weather conditions finally helped clear much of the smoke. By Sunday, July 19, New York City's air quality had returned to the Moderate category, with an AQI of approximately 78 that morning.

That day, NYC Emergency Management officially concluded its citywide wildfire-smoke response, calling the episode the second-most severe smoke event in the city's modern record. 

A July That Turned the Sky Orange

For New Yorkers and Long Islanders, the July 2026 wildfire episode was a vivid reminder that wildfires thousands of miles away can have an immediate impact on life here. From July 14 through July 19, smoke from Canadian fires transformed familiar blue summer skies into a hazy yellow-orange landscape, affected outdoor activities and created potentially dangerous breathing conditions.

For photographers, the event also produced some extraordinary and unusual images of New York City, Long Island beaches, the Atlantic Ocean and the setting sun, with landmarks appearing through layers of smoke and haze.
