The climate in Sanya is classified as a tropical wet and dry climate, known as Köppen Aw. This means the area experiences hot weather throughout the entire year. Monsoonal influences are very strong in this region. These influences create a lengthy wet season and a very pronounced dry season. The water temperatures in the surrounding sea remain warm all year long. January is typically the coolest month, while June is the hottest. Interestingly, June is much hotter in Sanya than in most other parts of China. Recent data shows the climate is warming. In 2024, the average annual temperature was 0.8 °C higher than the 1991 to 2020 average.
Sanya's history reaches back to the Qin dynasty, between 221 and 206 BCE. In ancient times, the area was known as Yazhou, which means "cliff state." Because it was so remote from political centers, people called it "the end of the sky and ocean." This extreme distance meant the city often served as a place of exile for officials. During the Tang dynasty, a Buddhist monk used the site as a staging post while traveling to Japan. The administrative history changed many times over the centuries. In 1912, Yazhou became Yaxian. After several mergers and separations involving nearby areas like Baoting and Lingshui, the area was upgraded. On 26 September 1987, the State Council approved its status as Sanya City. 
The city is divided into four distinct districts: Jiyang, Tianya, Haitang, and Yazhou. Each district has a different population density and land area. As of 2020, the total population of Sanya was 1,031,396 inhabitants. The built-up or metro area, which includes the Haitang and Jiyang districts, held 801,020 people. 
Tourism is a massive part of the local economy. Sanya hosts over 100 hotels, ranging from local resorts to international luxury brands. 
Transportation in Sanya is well-developed to support its large population and many visitors. The city is served by the Sanya Phoenix International Airport. For rail travel, the Hainan East Ring Intercity Rail connects Sanya to Haikou along the east coast. This trip takes approximately 1 hour and 22 minutes. 
Sanya is also becoming a center for specialized services like medical tourism. The Boao Lecheng International Medical Tourism Pilot Zone, also called Boao Hope City, is a special zone in the area. This pilot project was approved by the State Council in 2013. It allows for the use of specially licensed drugs and medical technologies. These may include equipment or drugs approved outside of China but not yet approved within the country. In 2023, Lecheng served approximately 300,000 medical tourists. This development connects Sanya to the global field of medical research and international healthcare services.
