Air Quality Index (AQI) & Outdoor Health Advisory for Honolulu
The air quality in Honolulu currently records a US AQI index of 56, placing local air conditions in the "Moderate" category. With an AQI score of 56, air quality is acceptable for the general public, though individuals exceptionally sensitive to particulate matter should monitor prolonged intense exertion outdoors. Major monitored pollutants include fine particulate matter PM2.5 at 12.3 µg/m³, coarse particulate PM10 at 20.7 µg/m³, ground-level ozone at 84 µg/m³, and nitrogen dioxide at 1.1 µg/m³.
Air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution. Individuals sensitive to air pollution—including young children, the elderly, and those managing asthma or cardiovascular sensitivities—should plan high-intensity outdoor exercises during hours of optimal atmospheric dispersion, and keep living spaces ventilated when ambient pollution indexes remain favorable.
