Ground-level ozone concentrations will be climbing in Maine on Monday, June 7, 2021 and are expected to reach unhealthy levels, according to the Maine Department of Environmental Protection (DEP), in a news release. Ozone levels have been high upwind since June 2.

High levels began around Lake Michigan and have been slowly migrating eastward. By Saturday June 5, southern New England had very high levels of ozone even reaching into the Unhealthy (red) category, said Maine DEP. Transport winds are expected to direct the higher values to Maine on Monday. The unhealthy levels of ozone are possible along the entire coastline and the Eastern Interior.

At elevated ozone levels, children, healthy adults who exert themselves, and individuals suffering from a respiratory disease such as asthma, bronchitis or COPD can experience reduced lung function and irritation. When this happens, individuals may notice a shortness of breath, coughing, throat irritation, and/or experience an uncomfortable sensation in their chest

Some actions you can take to protect your health during periods of unhealthy air quality include:

  • Adjusting your schedule to avoid strenuous outdoor activity during the afternoon.
