Why Is the Sky Yellow Today? Boston Air Quality "a Little Eerie" for Some.
The haze came from smoke from 800 active wildfires in Canada, and officials said it may keep temperatures a few degrees below forecast.
- On Wednesday, July 15, 2026, a thick plume of Canadian wildfire smoke blanketed Boston, turning the sky an unusual yellowish-brown hue and significantly impairing visibility across the region.
- More than 800 active wildfires burning in Canada, particularly in Western Ontario, are generating the smoke; winds transported this massive plume over 1,000 miles to New England.
- The Massachusetts Department of Environmental Protection issued an air quality alert for the state on Wednesday. The National Weather Service noted the smoke absorbed peak heating, keeping temperatures 5 to 10 degrees cooler than forecast.
- Dr. Sucharita Kher, a pulmonary critical care physician at Tufts Medical Center, advised residents: "It's a good day to have an air filter at home." Residents are modifying outdoor plans due to poor air quality.
- Persistent smoke is expected to linger through Thursday, with potential for air quality drops if concentrations reach ground level. A passing cold front may eventually bring scattered showers and relief from the haze.
