According to the Guinness Book of World Records, Yuma is the sunniest place on earth. Of the possible 4,456 hours of daylight each year, the sun shines in Yuma for roughly 4,050 hours, or about 90% of the time. Combine all that sunshine with the warmest winter weather in the country, and you've got a destination guaranteed to attract sun worshipers and other refugees from colder climes. In fact, each winter, tens of thousands of snowbirds (retired winter visitors) drive their RVs to Yuma from as far away as Canada. However, by late spring, all those RVers head north to escape the steadily rising temperatures, and by high summer, Yuma starts posting furnace-like high temperatures that make this one of the hottest cities in the country.

Way back in the middle of the 19th century, long before RVers discovered Yuma, this was one of the most important towns in the region, and known as the Rome of the Southwest because all roads led to Yuma Crossing—the shallow spot along the Colorado River where this town was founded. Despite its mid-desert location, Yuma became a busy port town during the 1850s as shallow-draft steamboats traveled up the Colorado River from the Gulf of California. In the 1870s,when the railroad pushed westward into California, it, too, passed through Yuma. Today, it is I-8, which connects San Diego with Tucson, that brings travelers to Yuma.

Yuma has more than a dozen golf courses and two important historic sites; it even has some claim to cinematic fame, with a range of movies from Beau Geste to The Empire Strikes Back having been filmed in the nearby sand dunes. Yet Yuma constantly struggles to attract visitors (blame it on the lure of San Diego, just a few hours away). It’s still primarily a place to escape the cold and snows up north.
