Air Quality Index for Maryland

The highest AQ index in Maryland (as of 14:00 EST) is currently the Lower Eastern Shore area. Ozone (OZONE) is measuring at 34 (Good). This means air quality is satisfactory, and air pollution poses little or no risk.

Over the next few days, the highest Particle Pollution (PM2.5) will be in the Hagerstown Region area. It is forecasted to be Moderate, meaning air quality is acceptable. However, there may be a risk for some people, particularly those who are unusually sensitive to air pollution.

Brisk northerly winds will usher in another round of cold Canadian air Saturday, resulting in Good air quality that will persist through Sunday. Winds will subside into Monday, with weaker vertical mixing as high pressure settles overhead. An uptick in fine particle concentrations is expected, though Good air quality should persist as the regional air quality modifies from pristine conditions. Into the middle of next week, including Christmas Eve and Day, weak vertical mixing and a relatively moist atmosphere will allow fine particles to climb into the Moderate AQI range, particularly where any wood stove/fireplace burning is prevalent.
