Sunshine is one of the few amenities that can’t be built, subsidized, or faked.
Across the U.S., a relatively small group of metro areas tends to dominate rankings for sunny days and total sunshine hours. Geography does most of the work. Latitude, elevation, desert climates, and rain shadows generally keep clouds scarce and skies clear.
The sunniest zip codes cluster largely in the Southwest and parts of inland California, where high-pressure systems limit rainfall and mountain ranges block incoming moisture. Coastal areas get their share of sun, but desert interiors usually win on consistency.
Here are six U.S. cities where sunshine is most abundant all year long.
