Delaware Air Quality Forecast Indicates 'Good' Levels for Ozone and PM2.5
US · Published Sep 14, 2026
• The Delaware Department of Natural Resources and Environmental Control (DNREC) has released its air quality forecast for September 13-14,
• The Air Quality Index (AQI) levels for ozone and PM2.5 are expected to remain in the 'Good' category, indicating satisfactory air quality with minimal health risks. Moderate northerly winds and a departing cold front are contributing to improved atmospheric mixing, while light easterly winds are expected to recirculate clean air masses across the state. The forecast also anticipates mostly sunny skies and temperatures in the low 80s °F (approximately 27 °C), which may aid ozone formation but are not expected to significantly impact air quality.

Impact & Risks

The forecasted 'Good' AQI levels for ozone and PM2.5 suggest minimal health risks for the general population. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, are unlikely to experience adverse effects under these conditions. However, DNREC advises residents to remain informed about air quality changes, as pollutant levels can vary due to weather patterns and localized emissions.
