Canadian Wildfire Smoke Expected to Reduce Air Quality Across New Jersey as Heat Intensifies

Smoke from large wildfires burning in western Ontario is expected to move across New Jersey and several other eastern states over the next few days, with weather officials warning that some of the smoke could reach ground level by Wednesday.

Light smoke has already begun spreading through the atmosphere over parts of New Jersey and New York City, creating hazy skies on Tuesday. Some residents may also notice a faint smoky smell while spending time outdoors.

Weather forecast models indicate that smoke concentrations are likely to increase on Wednesday as additional wildfire smoke drifts south from Canada. Forecasters say some of these smoke plumes could settle closer to the surface, leading to reduced air quality in parts of the region.

The smoky conditions are expected to arrive as another period of dangerous heat develops across New Jersey. Air temperatures are forecast to climb into the upper 90s, while high humidity is expected to make it feel as hot as 105 degrees in some locations.

Although the combination of extreme heat and wildfire smoke could create uncomfortable conditions, forecasters note that the thicker smoke may also block some sunlight. This could slightly limit daytime heating and reduce the intensity of the expected high temperatures.

Wildfire smoke from Canada has affected New Jersey several times in recent years. Changes in weather patterns and shifting wind directions can carry smoke from active Canadian wildfires hundreds of miles south into the northeastern United States.

Similar conditions were reported in early June 2025, when smoke from Canadian wildfires contributed to air quality alerts across 13 New Jersey counties as temperatures reached the mid- to upper 80s.

Another episode of Canadian wildfire smoke impacted the state again in August 2025.

One of the most significant smoke events occurred during the summer of 2023, when widespread wildfires across Canada produced dense smoke that spread into New Jersey and other parts of the Northeast, creating poor air quality and noticeably smoky conditions in many communities.

As smoke continues moving into the region, residents across New Jersey may experience hazy skies and periods of reduced air quality while the latest stretch of extreme heat settles over the state.
