Breaking: Air Quality Alert Issued for New York City Due to Ozone and Wildfire Smoke

New York City and several surrounding counties are under an air Quality Alert today, Wednesday, June 5, 2025. Teh alert, which spans from 11 A.M. to 11 P.M., is due to a combination of high ozone levels and smoke from Canadian wildfires impacting air quality.

This warning affects New York City, Dutchess, Orange, Putnam, Rockland, Sullivan, Ulster, and westchester counties. western New York, including Cattaraugus, Chautauqua, Erie, Genesee, Niagara, Orleans, and Wyoming counties, is also under the advisory. Long Island and the Jersey Shore are currently not expected to be affected.

Why the Air Quality Alert? A Dual Threat

The primary cause of this alert is elevated ozone levels, a common summer issue in New York City exacerbated by heat and humidity. Additionally, smoke from numerous Canadian wildfires is drifting into the region, further degrading air quality.

Ozone forms when pollutants from vehicles and industrial sources react with sunlight, creating fine particulates that can lead to respiratory issues.The situation is worsened by smoke from wildfires, which introduces additional particulate matter into the atmosphere. According to the EPA, ground-level ozone pollution continues to pose significant health concerns across many U.S. cities as of 2024, underscoring the importance of such alerts. EPA Official Website

Understanding the Air Quality Index (AQI)

The Air Quality Index (AQI) is a crucial tool for understanding air pollution and its associated health hazards. It uses a color-coded system to represent different levels of air quality.

AQI Level	Rating	Description
0-50	Good (Green)	Air quality is satisfactory.
51-100	Moderate (Yellow)	Acceptable, but some pollutants may pose a moderate health concern.
101-150	Unhealthy for Sensitive Groups (Orange)	Sensitive groups may experience health effects.
151-200	Unhealthy (Red)	Everyone may begin to experience health effects.
201-300	Very Unhealthy (Purple)	Significant health risk to everyone.
301+	Hazardous (Maroon)	Health emergency.

An Air Quality Alert is typically issued when the AQI exceeds 100. Today’s AQI is expected to be around 105.

Who is Most at Risk?

Sensitive groups, including individuals with heart or lung disease, older adults, children, and pregnant women, are particularly vulnerable during air quality alerts.

Why is the Sun or Moon Red? The Science Behind the Haze

Smoke from wildfires can cause the sun and moon to appear reddish. This phenomenon occurs because smoke introduces particulate matter into the atmosphere, scattering sunlight differently.

Blue light, with its shorter wavelengths, is scattered more effectively, while red light, with longer wavelengths, is able to penetrate the smoke, giving the sun and moon a reddish hue.

Did You Know? This same scattering effect is why sunsets often appear redder than midday skies.

  NYC air Quality Alert: Navigating Canadian Wildfire Smoke and Protecting your Health

  New Yorkers are facing heightened concerns amidst the latest NYC Air Quality Alert due to the pervasive impact of Canadian Wildfire Smoke. This article provides a comprehensive guide to understanding the risks, monitoring conditions, and taking proactive steps to safeguard your well-being. We’ll break down the specifics of PM2.5 levels, discuss the associated health impacts, and offer practical advice for managing the situation.

  Understanding the Impact: Canadian Wildfire Smoke on NYC Air Quality

  The influx of smoke from Canadian wildfires has significantly deteriorated air quality in NYC. This persistent “haze” is not merely an inconvenience; it poses a health risk for all citizens, particularly those with pre-existing conditions. The primary concern arises from fine particulate matter (PM2.5), tiny particles that can penetrate deep into the lungs and bloodstream.

  what is PM2.5 and Why Does it Matter?

  PM2.5 refers to inhalable particles with a diameter of 2.5 micrometers or less – about 30 times smaller than the width of a human hair. These particles are a key indicator of air pollution. They originate from a variety of sources, including:

  • Burning of wood and other biomass (like wildfires).
  • Vehicle exhaust
  • Industrial emissions.
  • Construction activities

  Elevated PM2.5 levels from the Canadian wildfires present a significant challenge to air quality and are associated with the NYC Air Quality Alert. Exposure to these pollutants can trigger a range of health problems.

  Real-world PM2.5 Levels in NYC: A Case Study

  During the peak of the wildfire smoke impact, PM2.5 levels in New York City soared. Let’s look at a simplified illustration:

  Date	PM2.5 Level (µg/m³)	Air Quality Index (AQI)	Air Quality Classification
