Heat in the city: taking the temperature of America’s hot spots

Published on August 22, 2018

Heat patterns across 20 major city centers in U.S. highlight difference in temperature ranges of up to 37 degrees

Toronto, ON - August 22, 2018 - The hottest spots and coolest areas of America’s top 20 cities by population have been compiled in an interactive heat map by Geotab, a global leader in IoT and connected transportation. Created by taking hyper-local temperature readings at more than 50,000 points across the included cities on the same day and time, the “Heat in the City” maps depict considerable variations.

The greatest temperature ranges were found in Los Angeles (37°F, with a high of 108°F and a low of 71°F) and Phoenix (30°F, with a high of 115°F and a low of 85°F). Seattle experienced the lowest temperature range of 8°F, with a high of 70°F and a low of 62°F.

With temperatures continuing to rise, Geotab’s “Heat in the City” maps utilized data collected from hundreds of thousands of vehicles across the United States to visually represent how 20 of the most populous cities in America can feel warmer in certain spots due to a variety of factors.

“As cities across the globe expand, having visibility into temperature patterns may become increasingly important for municipalities committed to creating energy-efficient urban environments and smarter cities,” said Mike Branch, Geotab’s VP of Data and Analytics. “By leveraging data such as hyper-local temperature data, cities are not only equipping themselves with the tools to make progressively informed decisions, but build safer and more sustainable communities for all.”

The 20 cities shown are the most populous metropolitan areas in the US, according to the Census Bureau Population Estimates of 2016. Temperature maps were created using an Inverse Distance Weighting algorithm from temperatures recorded with Geotab GO devices at more than 55,000 points across these cities at 12 PM on June 21st, 2017, the longest day of the year and first day of summer.
