How Many Sunny Days Does Los Angeles Get Per Year?

Los Angeles, California enjoys one of the best climates in the United States. Because of its Mediterranean climate, the average weather in the city is pleasant year round. If you’re curious how many sunny days in Los Angeles you can enjoy during an average year, this article is for you. We’re going to explore how often sun shines in the City of Angels and how many days of rain it gets.

Los Angeles averages in this article come from the NOAA (National Oceanic and Atmospheric Administration).

Here’s the Number of Sunny Days in Los Angeles, California

According to the NOAA, the University of Southern California (located in downtown Los Angeles) receives 3,254 sunshine hours a year. Note that various locations in the Los Angeles metropolitan area may have very different conditions due to local microclimates.

When we look at percentage of daylight hours when there’s sun (percent possible sunshine), we can calculate how many sunny days Los Angeles gets on average per year.

Here are my calculations to determine how often you can expect blue skies in Los Angeles:

MonthSunshine hoursPercent possible sunshineAverage sunny days

According to this data, Los Angeles has about 267 sunny days per year, defined as both partly cloudy and clear days. This means that Los Angeles has 98 days of cloudy weather.

The sunniest month is August with 26 sunny days. It’s also the hottest month when temperatures range from about 65 °F on average at night to 84 °F during the day. Among the largest cities in California, Los Angeles still has relatively mild summers, though.

Due to the phenomenon known as “June Gloom” (that’s most prevalent in the late spring and early summer), the least sunny month is June with about 19 sunny days (May is also more cloudy, recording 19-20 days of sun).

Despite more frequent cloud cover in May and June, Los Angeles is still one one of the sunniest cities in the United States and also one of the sunniest on the west coast.

In California, Los Angeles is roughly in between the sunnier and slightly cloudier cities.

San Diego gets 3,054 hours of sun, while San Francisco gets 3,062. Sacramento, known for its hot summer, is far ahead of Los Angeles, with 3,608 hours of sunshine. Fresno is also much sunnier. It receives 3,564 hours of sun.

Phoenix, the sunniest city in the US among large cities, is a little closer to LA but still far ahead. It records 3,872 sunshine hours.

Leaving California, Las Vegas, Nevada, as one of the sunniest cities in the United States, also provides sunny skies much more often. It has 3,825 hours of sunshine.

El Paso, Texas, is also a much sunnier destination. It receives 3,763 hours of sun (there’s a reason why it’s nicknamed The Sun City).

Miami is less sunny than Los Angeles, recording 3,154 sunshine hours. But Key West is sunnier with 3,404 hours of sunshine.

For example, New York City gets 2,535 sunshine hours a year. Chicago receives 2,508 hours (more on Chicago here), Boston 2,634, Philadelphia 2,498, and Washington 2,528.

Comparing California to cloudier cities in Texas, Houston gets 2,578 hours of sunshine, Austin 2,644, and San Antonio 2,629.
