Hazy Days Ahead as Canada’s Fires Cross the Border
Published Jul 29, 2025
New York City faces dual weather threats this week: extreme heat and wildfire smoke. A heat advisory is in effect through Wednesday, with feels-like temps nearing 100°F. Air quality, impacted by Canadian wildfire smoke, is worsening again. Health officials warn seniors and those with medical conditions to take precautions, as both heat and pollution levels pose serious health risks.
Extreme heat and wildfire smoke hit NYC
New York City is bracing for a challenging week as it faces the combined threats of extreme heat and hazardous air quality due to wildfire smoke drifting south from Canada. A heat advisory has been issued and will remain in effect through Wednesday, with temperatures expected to feel like they are approaching a sweltering 100°F (38°C). Residents are urged to take precautions to avoid heat-related illnesses.
Canadian wildfire smoke worsens air quality
Adding to the concern is the deteriorating air quality. Smoke from the ongoing wildfires in Canada is once again affecting the region, leading to elevated levels of pollutants in the air. This poses a significant risk, particularly for vulnerable populations such as seniors, young children, and individuals with pre-existing respiratory or cardiovascular conditions.
Limit outdoor activity, wear masks, stay hydrated
Health officials are strongly advising residents to limit their time outdoors, especially during peak hours of heat and pollution. If you must be outside, it is recommended to wear a high-quality mask, such as an N95, to filter out harmful particles. Staying hydrated and seeking air-conditioned environments are also crucial steps to mitigate the impact of these dual weather threats.
Protect health during dual weather threats
The combination of extreme heat and poor air quality can exacerbate health issues, leading to respiratory problems, heatstroke, and other serious conditions. It is essential for everyone to stay informed about the latest weather updates and heed the advice of local authorities to protect their health and well-being during this period. New Yorkers are known for their resilience, and by taking these precautions, the city can navigate this challenging weather event safely.
