A City Powered By Sunshine: Inside The Brightest Place On Earth
The World Record Holder For Sunshine: Yuma, Arizona holds the Guinness World Record for the sunniest city on Earth. The city averages about 4,015 hours of sunshine each year, meaning sunlight appears during more than 90 percent of daylight hours. Located in the southwestern corner of Arizona near the borders of California and Mexico, Yuma sits in the Sonoran Desert, one of the hottest and driest regions in North America. Meteorologists measure sunshine by tracking the number of hours when direct sunlight reaches the ground. Yuma’s clear skies rarely allow thick cloud cover, giving it a level of consistency that few places in the world can match. This steady sunshine has shaped the city’s identity, economy, and daily routines.
