What Makes a City “Sunny”?

Meteorologists measure sunshine by tracking the percentage of possible daylight hours that are actually sunny, along with the total annual hours of bright sunshine. Not surprisingly, the desert Southwest dominates the list thanks to its dry climate, low humidity, and frequent high-pressure systems.

1. Yuma, Arizona

Average Annual Sunshine: 4,015+ hours
Sunny Days: About 90% of daylight hours

If sunshine were a competitive sport, Yuma would take home the gold medal every year. Located in the southwestern corner of Arizona, Yuma is widely recognized as the sunniest city in the United States—and possibly the world. The city averages more than 4,000 hours of sunshine annually and enjoys clear skies roughly 90% of the time.

Winter visitors flock here for mild temperatures, abundant outdoor recreation, and virtually guaranteed sunshine.

Fun Fact: Yuma has been recognized by Guinness World Records as the “Sunniest City on Earth.”

2. Phoenix, Arizona

Average Annual Sunshine: 3,872 hours

Phoenix isn’t far behind its neighbor Yuma. Nestled in the Sonoran Desert, Arizona’s capital enjoys nearly 3,900 hours of sunshine each year. Long, hot summers and mild winters make outdoor activities possible nearly year-round.

The city is famous for its golf courses, hiking trails, and spectacular desert sunsets.

Fun Fact: Phoenix receives more sunshine than any major city on Earth.

3. Las Vegas, Nevada

Average Annual Sunshine: 3,825 hours

The entertainment capital of the world also happens to be one of the sunniest places in America. Las Vegas averages more than 300 sunny days each year and enjoys bright sunshine during about 86% of daylight hours.

Beyond the famous Strip, visitors can explore nearby Red Rock Canyon, Lake Mead, and the Mojave Desert under consistently clear skies.

Fun Fact: Las Vegas receives only about 4 inches of rain annually.

4. Tucson, Arizona

Average Annual Sunshine: 3,806 hours

Arizona claims another spot in the top five with Tucson. Surrounded by mountain ranges and saguaro-studded desert landscapes, Tucson enjoys sunny weather throughout the year. While summer monsoon storms occasionally bring dramatic afternoon clouds and lightning, sunshine remains the rule rather than the exception.

The city’s blend of outdoor adventure, rich history, and vibrant food scene makes it a favorite destination for sun seekers.

5. El Paso, Texas

Average Annual Sunshine: 3,763 hours

Rounding out the list is El Paso, Texas. Situated in the Chihuahuan Desert along the Rio Grande, El Paso enjoys more than 300 sunny days per year and some of the clearest skies in the Lone Star State.

The city’s high elevation and arid climate help keep humidity low, making even hot summer days feel more comfortable than in many other parts of the country.

Fun Fact: El Paso is often called the “Sun City” thanks to its abundance of bright, sunny days.

Why Are These Cities So Sunny?

Most of America’s sunniest cities are located in the Southwest, where desert climates naturally limit cloud formation and rainfall. Persistent high-pressure systems, low humidity, and abundant dry air help create ideal conditions for clear skies year-round.

Sunshine State? Not So Fast!

Despite its nickname, Florida doesn’t dominate the sunshine rankings. While cities like Miami receive plenty of sunny weather, desert locations in Arizona, Nevada, and Texas typically log hundreds more hours of sunshine each year.
