Scorching Three-Day Heatwave in New York City Creates Smog, Issues Air Quality Alerts, and Temperatures Reaching Feels-Like 105 Degrees
New York City Under Air Quality Health Advisory Due to Canadian Wildfires and Heat Wave
New York City is currently experiencing poor air quality conditions from July 28 to July 31, 2025, with Air Quality Health Advisories issued for July 29 and 30. The advisory is in effect daily from 11 a.m. to 11 p.m., as the city grapples with elevated levels of ozone, a major component of photochemical smog.
The air quality in NYC has been unfavorable, with an AQI of 60, according to AirNow. This is considered unhealthy for sensitive groups such as the elderly, children, and those with respiratory or heart conditions. The high levels of ozone are likely due to hot, sunny weather conditions that promote ground-level ozone formation.
The New York State Department of Environmental Conservation issued a health air quality alert on Tuesday, July 29, from 11 AM to 11 PM. The alert was issued due to the formation of ground-level ozone, a major component of photochemical smog. Motor vehicle exhaust and out-of-state emissions sources are the primary sources of ground-level ozone and the largest air pollution problems in the Northeast.
Regarding heat conditions, Tuesday, July 29, is predicted to be the hottest day of the week, with a high of 97°F. The Weather Channel predicts the low temperature on Tuesday to be 78°F. Isolated thunderstorms are expected on Thursday, July 31, and temperatures will significantly drop, reaching a high of 79°F and a low of 67°F.
Precautions in place include recommendations for the elderly, individuals with health risks (respiratory or heart issues), young children, and people who exercise outdoors to limit strenuous outdoor activities, especially from midday through early evening when ozone peaks. Advisories for those who experience irritation (eye, nose, throat), shortness of breath, or chest pain to seek medical assistance promptly have also been issued.
Residents without air conditioning are encouraged to seek cooler environments when possible, although specific details on cooling centers or other provisions were not included in the search results. However, New York State typically activates cooling centers during heat waves, especially targeting vulnerable populations.
The NYC Emergency Management website is a reliable source for the latest information on forecasts and air quality. It is advisable to check municipal websites or local government announcements directly for heat-related precautionary measures and cooling center locations.
In summary, due to ozone pollution and likely hot weather, elderly individuals, those with health conditions, and people without air conditioning are advised to stay indoors during peak ozone hours, avoid strenuous activity, monitor symptoms, and make use of local resources such as cooling centers if available.

- The high temperatures and sunny weather conditions in New York City may contribute to a rise in fever due to the body's natural response to heat, making it essential for sensitive groups, such as the elderly and those with heart or respiratory conditions, to be extra cautious.
- Given the increased occurrence of climate-related events like heat waves and climate-change-induced wildfires, it is crucial for environmental science and weather researchers to collaborate more closely to predict and mitigate such events in the future, which could potentially save countless lives and improve the overall health of our planet.
