The Extreme Heat Map Tool shows the land surface temperature data for the Twin Cities metro area. Communities may use this tool to determine which areas within their community are most susceptible to extreme heat. We hope that this tool will help cities prioritize policy and implementation strategies (for instance, targeted tree planting or design improvements that may mitigate risks associated with extreme heat). The effect of this heat is often called the Urban Heat Island Effect (UHI) which consists of urban or rural center areas that are significantly warmer than surrounding rural areas due to human activities.
The tool is useful in demonstrating the difference in land surface temperature across the metro region due to the existing built and natural environment, a product of land use, site design, and land cover. By changing our built and natural environments through policies, implementation, and sensible site design, we can reduce this extreme heat effect and thereby improve public health and livability.
A map of land surface temperature highlights differences in temperature across the region. Raster data of land surface temperature is available for custom mapping and analysis (2022 data
and 2016 data
