How Heat Impacts Unhoused Vermonters
Climate change is making heat waves in Vermont hotter, last longer, and happen more often. Hot weather can cause serious health problems, like heat exhaustion and heat stroke. Some people are harmed more than others because they lack economic, social or political resources.
The number of days when temperatures reach 90°F at the Burlington Airport have increased from about 8 times per year from 1991 to 2020 to about 15 times a year since 2020.
The unhoused population in Vermont has also more than tripled since 2020. In 2024, Vermont had the fourth highest rate of houselessness in the country.
People who are unhoused are believed to be at especially high risk for heat-related illnesses, but it can be difficult to confirm this using traditional health data. Heat illnesses are often not reported because many unhoused people cannot get medical care, and medical records rarely include housing status.
To help better understand how hot weather affects unhoused Vermonters – and what support they need – the Health Department partnered with Middlebury College. Together, we listened to unhoused Vermonters and the people who provide services to them. You can listen to their stories below.
