2020 Heat Mapping CAMPAIGN Data & REPORTS

This story map created by HARC explores why H3AT was formed, how the 2020 campaign was conducted, and provides a high level analysis of the results.


>>> We recommend starting here if you are unfamiliar with the campaign!

Discover Houston and Harris County's hottest places mapped during our 2020 heat mapping campaign. Type your address into the map and explore different map layers (observed temperature, or "traverse points"; modeled temperature; and modeled heat index), for the morning, afternoon, and evening of August 7, 2020. No ArcGIS subscription required.

For advanced, licensed ArcGIS Online users to more broadly interact with the results, bring in additional data layers, perform analyses, or pull these layers into other new or existing web maps.

CIty of Houston HEAT initiatives

H3AT is featured in the City of Houston's resilience strategy as sub-action 16.1: Launch an urban heat island mapping campaign, to make Houston neighborhoods greener and cooler to combat extreme heat.


The City of Houston’s Mayor’s Office released the Houston Climate Impact Assessment, to better illustrate how climate change will impact Houston’s future based on lower and higher scenarios of future climate change. The assessment, conducted by Anne Stoner and Katharine Hayhoe of ATMOS Research & Consulting, studied 25 separate future climate indicators, including the number of days with temperatures above 100 degrees, the number of nights above 80 degrees, total annual precipitation, days with precipitation above 4 inches, and the annual number of dry days.

Extreme Heat Takeaways: By 2050, if we do not curb our greenhouse gas emissions globally, we can expect...

  • the hottest day of summer will be 7 degrees warmer than today,

  • there will be 22 more days that exceed 100°F,

  • there will be 50 more nights that exceed 80°F, and

  • summers overall will be 55 days longer than today.

HARRIS COUNTY HEAT INITIATIVES

Harris County Public Health's Climate Program

Their Extreme Heat Vulnerability Assessment is the first of several climate vulnerability assessments the Climate Program has planned. Communities with the most exposure, the highest population sensitivity, and the least ability to adapt will be identified as the highest priority for public health interventions.

  • The Climate Program also developed a Heat Vulnerability Story Map that provides information about the vulnerability assessment process and why they looked at certain indicators.
