The heat maps are here! Check out our interactive StoryMap to learn more:


CAPA’s Heat Watch Report for Charlotte is now available online:

The raw GIS traverse (vector) data from our mapping campaign day and the resultant raster “heat map” temperature visualizations (raster) can also be downloaded here.


We are excited to announce that the Charlotte Heat Mappers are now a member organization of the Charlotte Mecklenburg Climate Leaders, a broad coalition of Charlotte-area organizations working to ensure the City of Charlotte, Mecklenburg County, and its municipalities set and meet ambitious climate goals. We share common goals of improving the health of our communities by advocating for equitable clean energy, carbon-reduction strategies, and climate justice.

What is an Urban Heat Island?

An Urban Heat Island (UHI) occurs when a city experiences much higher temperatures than nearby rural areas due to a concentration of surfaces and building materials that absorb and hold heat. Learn more at https://climatekids.nasa.gov/heat-islands/

Why is it important to map urban heat?

When combined with conditions such as high humidity, sun exposure, and poor air quality, extreme temperatures can pose serious health risks for individuals, and not all areas and groups are affected equally. To learn more about who faces the greatest risk of heat-related illness, visit https://www.heat.gov/pages/who-is-at-risk-to-extreme-heat
