They don’t call California the Golden State for nothing. Situated on the western edge of the Sun Belt, California’s reputation for gold may be historical, but its presence in “Sunniest Cities” lists makes its weather a major part of its modern appeal.
As one of the sunniest states in the country, California homeowners and businesses have benefited hugely from natural daylighting. Early sunrises and late sunsets give California a unique suitability for daylighting that many states simply don’t have.
In this blog post, we’ll look at the best cities and regions within California for homes and workplaces with skylights and other daylighting systems. Read on to see if your city or place of business ranks within the top five.
California’s fifth largest city is also its sunniest. Fresno is one of the sunniest cities in the United States, with 79% of all days featuring a warm and brightly lit sky. In fact, only sixcities in the entire country receive more sunlight throughout the year.
Fresno’s summer weather is some of the best in the country for naturally lit homes and businesses. In July, the city’s warmest and sunniest month, 97% of all days are brightly lit by the summer sun, helping eco-friendly homes reduce their expenses.
Like other inland California cities, Fresno’s winter isn’t quite as ideal for daylighting as its summer. Dense fog reduces visibility in December and January, although light levels are still suitable for homes and businesses that use natural daylighting.
California’s state capital is the sunniest in the country. Sacramento receives more sunlight than all but nine cities in the United States, with 78% of days lit up by the sun and few affected by rainfall.
Like Fresno and other inland cities, Sacramento’s sunlight hours peak during June, July and other summer months. From July to September, the city is officially ranked as the world’s sunniest location.
Despite the smog, Los Angeles ranks close to the top of the United States’ sunniest cities. The City of Angels receives more sunlight than any other large metropolitan area in the country, with the sole exception of Phoenix, Arizona.
73% of Los Angeles days are sunny, with a total of 147 completely clear days every year. Unlike cities further inland, much of Los Angeles’ heat is regulated by its close proximity to the coast, which makes its year-round sunlight far more comfortable.
Keeping up the sunny reputation of Southern California, San Diego receives more than 3055 hours of sunshine every year. Sunny more than 68% of the daytime, it’s one of the best locations on the West Coast for energy efficient businesses.
In fact, San Diego’s climate is one of the most desirable in the world. Near constant sunshine and comfortable temperatures moderated by its closeness to the sea have made it one of the top-ten best world climates, according to the Farmer’s Almanac.
Although it might be best known for its foggy mornings, San Francisco is actually one of the sunniest cities in the United States. It enjoys more than 160 clear days every year and 66% sunshine – not bad for a place nicknamed Fog City.
Despite its year-round sunny weather, San Francisco’s climate does have several small issues for energy-efficient businesses interested in reducing their artificial lighting dependence.
Its microclimates mean that some areas receive more rain than others, which can reduce sunlight in many parts of the city. San Francisco is also affected by famous summer fog, which is caused by the North Pacific High anticyclone.
Is your city not on the list? Don’t worry
No matter where your home or business is located, you can benefit from installing daylighting in your home. Even at the peak of winter, skylights and other sources of natural light can help you massively reduce your home’s total energy consumption.
