Southwest USA
To be more precise, Arizona is the sunniest place on the planet. The southwest city of Yuma, bordering California and Mexico, is widely recognised as the world’s sunniest city, boasting an incredible 91 percent sunny daylight hours every year. In hours, this comes to more than 4,000 hours per year, 400 hours of glorious sunshine every month, and about 11 hours of radiant heat daily. Put bluntly: don’t worry about a winter jacket here. But do remember sunglasses, sunscreen, a good hat, a lot of water and a keen eye for the shade.
