Welcome to the San Diego Heat Risk Explorer

Quick start

  1. Defaults are already selected — click Build Composite Risk Map.
  2. Click any tract to see its risk score and dominant driver.
  3. Under Map Layer, switch to Dominant Driver to see what drives risk countywide.

Or use the left panel to customize your map. Here’s what each section does:

  • Heat Exposure / Population Sensitivity / Adaptive Capacity — three groups of factors that shape heat risk. Turn any on or off to include them in your map.
  • Build Composite Risk Map — combines the factors you picked into a single risk score for every census tract.
  • Map Layer — switch between the combined risk score, each group on its own, or any single factor.
  • Jurisdictions — show city or tribal-land boundaries on the map.
  • Climate Scenario — see how risk shifts under future warming, for the year 2050 or 2080.
  • Accessibility — switch to colorblind-friendly colors.
  • Export — save the current map as a PDF or download the data.
