Significance Statement
Energy poverty alleviation programs have focused primarily on cold season warming rather than warm season cooling. However, summertime energy burden may be an increasing concern for minoritized households nationwide. In this study we found that Latino and Black households consistently experience warmer summers, as measured by near-surface air temperature within the same county across 13 states of the northeast and mid-Atlantic United States. Present-day residential segregation represents a likely pathway. Segregation often overlaps with other place-based inequalities, so hotter summers for households burdened with poor housing quality, poverty, and health disparities indicate limited adaptive capacity for ethnoracial minorities and the need for housing and energy policy interventions.
