The Sunniest Cities in the U.S.
If you’re chasing sunshine, certain cities in the United States consistently deliver. Phoenix, Tucson, and Las Vegas lead the pack, boasting the highest percentages of possible sunshine among U.S. Cities with populations exceeding 100,000. These figures are typically averaged over decades to provide a reliable picture of typical conditions. Factors like subtropical high-pressure systems, mountain rain shadows, and arid landscapes contribute to the abundance of clear skies in these regions.
The 10 Sunniest Cities in the U.S.
| Rank | City, State | % of Possible Sunshine |
|---|---|---|
| 1 (tie) | Phoenix, Arizona | 85% |
| 1 (tie) | Tucson, Arizona | 85% |
| 3 | Las Vegas, Nevada | 84% |
| 4 | El Paso, Texas | 83% |

| 10 | Colorado Springs, Colorado | 72% |
Phoenix, Arizona (85%)
Phoenix, situated in the Sonoran Desert, receives an average of 3,872 hours of sunshine annually, more than any other major city on Earth.1 Its exceptional sunshine is attributed to a subtropical high-pressure zone, a surrounding ring of mountains creating a rain-shadow effect, and a dry, sparsely vegetated landscape. The descending air warms and dries, inhibiting cloud formation, and the mountains force moisture to precipitate before reaching the valley.
Tucson, Arizona (85%)
Located in the Sonoran Desert at approximately 2,450 feet elevation, Tucson’s climate is classified as hot desert, but its location and elevation provide some moderation. Intense surface heating, low-level moisture, and air rising along the Mogollon Rim and surrounding mountains can trigger brief, intense thunderstorms, followed by quickly clearing skies.1
Las Vegas, Nevada (84%)
Las Vegas, nestled in a basin in the Mojave Desert, is encircled by mountain ranges. Like Phoenix, it benefits from a rain-shadow effect. Moist air from the Pacific hits the Sierra Nevada and other coastal ranges, releasing precipitation on the windward slopes. By the time the air descends into Nevada, it is warm and dry.2 High-pressure systems also contribute to the city’s abundant sunshine.
El Paso, Texas (83%)
El Paso, situated where the Chihuahuan Desert meets the Franklin Mountains, experiences sunshine approximately 83% of the time.1 Persistent high-pressure systems suppress cloud formation, and surrounding mountains create a rain-shadow effect, limiting moisture from the Pacific. Its inland location also reduces the influence of humid Gulf air.
Reno, Nevada (81%)
Reno’s location on the western edge of Nevada, with the Sierra Nevada to the west, is ideal for sunshine. Storms from the Pacific drop much of their moisture on the Sierra’s slopes, arriving in Reno as drier air. The region’s high desert climate also keeps humidity low.1
Fresno, California (79%)
Fresno, in California’s Central Valley, benefits from a Mediterranean climate with long, dry summers. The North Pacific High creates air that warms and dries, preventing cloud formation. The surrounding mountain ranges enhance the dryness, as moist air releases precipitation on the windward slopes.1
Sacramento, California (77%)
Sacramento experiences sunshine thanks to the North Pacific High, which nudges storm tracks north during the summer. Its inland position often keeps it clearer than coastal California.1
Albuquerque, New Mexico (76%)
Located in the high desert of central New Mexico, Albuquerque enjoys sunshine about 76% of the time due to its elevation, arid climate, and the rain shadow effect of the Sandia and Manzano Mountains.3
Bakersfield, California (76%)
Bakersfield, at the southern complete of the San Joaquin Valley, benefits from a bowl-like landscape and surrounding ranges that preserve skies clear. Like Fresno, it experiences the influence of the North Pacific High during the summer months.1
Colorado Springs, Colorado (72%)
Colorado Springs rounds out the top 10 with sunshine on the Front Range. Its high elevation and the rain shadow effect of the Rocky Mountains contribute to clear skies.1
The United States offers a diverse range of sunny destinations, each shaped by unique geographical and atmospheric factors. Whether you prefer the desert climates of Arizona and Nevada or the high-altitude sunshine of Colorado, there’s a location to suit your preference.
