Air Quality Index (AQI) in Boston

Monitoring air quality is crucial for protecting your health, especially for sensitive groups. Our Boston air quality monitoring tracks several key pollutants in real-time:

• PM2.5 (Fine Particulate Matter) – Microscopic particles that can penetrate deep into lungs and enter the bloodstream, particularly dangerous for respiratory and cardiovascular health
• PM10 (Coarse Particulate Matter) – Larger particles from dust, pollen, and mold that can irritate airways and trigger allergies
• Ozone (O₃) – Ground-level ozone that can cause breathing difficulties, particularly during warm, sunny conditions
• Nitrogen Dioxide (NO₂) – A traffic-related pollutant that indicates overall air pollution levels in urban areas
• Carbon Monoxide (CO) – A colorless, odorless gas produced by incomplete combustion
• Sulfur Dioxide (SO₂) – An industrial pollutant that can affect respiratory health

The US Air Quality Index (AQI) scale ranges from 0 to 500, divided into six categories: Good (0-50), Moderate (51-100), Unhealthy for Sensitive Groups (101-150), Unhealthy (151-200), Very Unhealthy (201-300), and Hazardous (301-500). Each level comes with specific activity recommendations to protect your health.

UV Index and Sun Protection in Boston

The Boston UV index measures the strength of ultraviolet radiation from the sun. Understanding UV levels is essential for preventing sunburn, premature skin aging, and reducing skin cancer risk. Our UV monitoring provides:

• Low (1-2) – Minimal protection needed for most people
• Moderate (3-5) – Sunscreen and sunglasses recommended, seek shade during midday hours
• High (6-7) – Protection essential, reduce sun exposure between 10am and 4pm
• Very High (8-10) – Extra precautions needed, minimize midday sun exposure
• Extreme (11+) – Maximum protection required, avoid being outside during midday

Over the next 16 days, the maximum UV index in Boston is expected to reach 3, so plan your sun protection accordingly.
