Sunniest Places and Countries in the World

Two regions dominate the top ten list of the sunniest places in the world. Half of the ten sunniest places on record are in the American southwest states of Arizona, Nevada and Texas. The other sunny region is in northeast Africa. It spans southern Egypt, northern Sudan and northern Chad, taking in the Nile Valley and deserts to the west.

Yuma, located in western Arizona near the borders with Mexico and California, is the only place on earth confirmed to bask in more than 4000 hours of sunshine a year. Altogether 90 percent of the daylight in Yuma is sunny. Year round, Yuma averages 11 hours of sun a day.

Yuma's sunniest month is June, when it's sunny for 97 percent of the time between sunrise to sunset. The month gets a total 415 hours of sunshine.

The rankings here are based on the sunshine averages for 1961 to 1990 that were provided for 129 countries and territories to the World Meteorological Organization. These come from 1800 weather stations scattered across all the continents, ranging from the Antarctic to the northern tip of North America. Altogether, climate stations around the world average 2334 hours of sun a year, equal to 6 hours and 24 minutes of sunshine a day.

Places With the Most Sunshine Each Month

Despite its unsurpassed annual total of sunny hours, Yuma only tops the list of sunniest places for one month a year. Rather than a spike of sunny weather for a season or two, Yuma's claim to sunniest spot comes from having reliably sunny weather all year long, never dropping below an average eight hours a day in any month.

The sunniest month of all worldwide is in May at Eureka in northern Canada. The Arctic outpost on Ellesmere Island, averages 16.5 hours of sun a day for May. That total is just the bright sunshine and doesn't count faint rays skimming across the horizon.

Canada's Nunavut Territory is also where the most sunshine happens in April. Alert is the northernmost permanent settlement in the world, located at the northeast end of Ellesmere Island, just 817 kilometres (508 miles) from the North Pole and in April has 377 sunny hours. Being so far north, all those hours of bright sun account for only 55 percent of Alert's daylight.

But the land of the midnight sun gets enough cloud during summer for the world's sunniest spot to shift all the way south to Sacramento, California. During July, Sacramento achieves the sunniest month for any city on earth with an average of 14 hours and 12 minutes a day, accounting for 98 percent of its daylight time.

During the northern hemisphere's winter, the sunniest places move south of the equator. Uppington, a town in Northern Cape province of South Africa tops the list for sunshine from November through January.

During the shoulder seasons, sunny regions in Asia take over. Songkhla, a city on the Malay Peninsula of southern Thailand is the world's sunniest spot in February and Khalkhgol in eastern Mongolia has the most sun for October.
