Newcastle County faces rising temperatures and increasing health risks from heat waves

The New Castle County Public Safety Committee meeting held on July 8, 2025, focused on the rising temperatures and their implications for public health and safety in the region. The meeting began with a presentation highlighting that the average annual temperature in New Castle County has increased by over three degrees during the twentieth century, with projections indicating a continued rise.

A key point of discussion was the expected increase in the number of days with temperatures exceeding 95 degrees. Currently, the county experiences about five such days annually, but this number is anticipated to rise to as many as 40 days by 2040. This trend raises concerns about more frequent and prolonged heat waves, which can lead to health issues, particularly for vulnerable populations lacking access to cooling resources.

The committee noted that urban areas, especially along the Wilmington city limits and Route 9 Corridor, are particularly affected by the urban heat island effect. This phenomenon results from extensive pavement and low tree canopy, causing ambient temperatures to rise significantly. The heat index, which combines temperature and humidity, can make it feel much hotter than the actual temperature, posing additional risks to public health.

Socioeconomic factors were also discussed, with many residents living in older homes that lack adequate insulation or air conditioning. This situation exacerbates the health risks associated with extreme heat, especially for those who cannot afford to upgrade their living conditions.

The meeting also addressed the operation of cooling centers in New Castle County. Currently, non-profit organizations, such as the Friendship House, lead the initiative to provide cooling resources during extreme heat events. The Friendship House was unable to attend the meeting due to activation for a Code Orange day, which indicates extreme heat conditions.

In conclusion, the meeting underscored the urgent need for strategies to address the rising temperatures and their impact on public health in New Castle County. The committee emphasized the importance of collaboration between government and non-profit organizations to enhance cooling resources and support for vulnerable populations as climate conditions continue to evolve.
