Sunniest cities in the world

Have you ever wondered why you feel happier when the sun is shining? Scientists have confirmed that exposure to sunlight increases the serotonin levels in your brain. Serotonin is a hormone that produces positive feelings, such as happiness, satisfaction, and optimism. 

But sunlight is not just beneficial for your mood. Spending time in the sunshine has health benefits too. It increases your body’s production of Vitamin D, which is essential for preventing disease, lowering blood pressure, and supporting bone health.

So, sun-worshippers, keep reading. In this article, we’ll reveal the ten sunniest cities in the world — which should provide more than enough inspiration for your next vacation.

1. Yuma, United States

Hours of average annual sunshine: 4,015

Yuma is the world’s sunniest city, with an average of 4,015 hours of sunshine a year. That works out at more than 300 sunny days a year or 11 hours of sunshine a day. Put another way, 91 percent of the city’s daylight hours are filled with sunshine!

As well as being the sunniest place on Earth, Yuma is extremely hot and dry due to its desert climate. Located in the Sonoran Desert in the US state of Arizona, it only receives about 3.4 inches of rain per year, and temperatures soar during the summer months. July is especially hot, with typical highs of 107°F (41.7°C). The highest temperature ever recorded in Yuma was 124 degrees Fahrenheit (51.1°C) in July 1995.

2. Marsa Alam, Egypt

The city of Marsa Alam in Egypt receives 3,958 hours of sunlight, making it the second sunniest place on Earth.

Like Yuma, the city experiences a hot desert climate, with steadier temperatures than the neighboring cities of Hurghada and Sharm el Sheikh. In May 2010, Marsa Alam reached 113 degrees Fahrenheit (45°C) — the highest temperature ever recorded in the city. 

Dubbed the “Egyptian Maldives”, Marsa Alam is fast becoming one of the most popular tourist destinations in Egypt, thanks to its sunny climate, white sandy beaches, and crystal clear water. 

3. Dakhla Oasis, Egypt

Phoenix experiences a subtropical desert climate thanks to its location in the Sonoran Desert.

Temperatures during summer reach average highs of 104°F (40°C), with a record high of 122°F (50°C) recorded in June 1990. Overall, the temperature in Phoenix never drops below 51°F (10.6°C) — even during the winter.

Like the rest of the cities on this list, Keetmanshoop has a hot desert climate. Situated on the edge of the Kalahari Desert in southern Namibia, it has extremely hot long summers and short cold winters. It only receives about six inches of annual rainfall, and temperatures are moderate throughout the year.

On average, temperatures reach highs of 83.8°F (28.8°C) and lows of 55.9°F (13.3°C). However, the annual mean temperature of the city is 70°F (21.1 °C).

Located in the country’s driest state, Nevada, Las Vegas is like an oasis in the Mojave Desert. Again, the city has a subtropical, hot desert climate, and for five months of the year, the average temperature reaches at least 90°F (32.2°C).

Known as both “Sin City” and the “Entertainment Capital of the World”, Las Vegas is famous for gambling, pool parties, and novelty weddings. However, many tourists also visit the city because it is sunny 85 percent of the time.

Like Yuma and Phoenix, Tucson is located in the Sonoran Desert. However, it is slightly cooler and wetter because it has a higher elevation.
