Research by Geotab shows that the urban heat island effect can vary dramatically within the same city.
The fleet management analytics firm has released temperature gradient maps of the largest U.S. cities that take the temperature of different areas of each city. Los Angeles, at 37°F, had the most variability from the hottest to the coolest location. Seattle had the lowest variation at 6°F.
The interactive maps were created by taking hyper-local temperature readings at more than 50,000 points across America’s 20 biggest cities on the same day and time (June 21st, 2017). City centers often feel far warmer in certain areas, due to factors including paved surfaces absorbing sunshine, buildings blocking airflow, and fewer trees.
The maps could be a reference for determining which areas of a city would most benefit from cool roofs, more trees, and other environmental cooling strategies.
