The Kingdom of Bhutan is a small landlocked country located in the southern foothills of the Himalayan mountain range, sandwiched between the People's Republic of China in the north and the Republic of India in the south. It is a sovereign nation, with a total land area of 38,394 km² and a total population of 735553 (2017).
Southern Bhutan has a hot and humid subtropical climate that is fairly unchanging throughout the year. Temperatures can vary between 15-30 degrees Celsius (59- 86 degrees Fahrenheit). In the Central parts of the country which consists of temperate and deciduous forests, the climate is more seasonal with warm summers and cool and dry winters. In the far Northern reaches of the kingdom, the weather is much colder during winter. Mountain peaks are perpetually covered in snow and lower parts are still cool in summer owing to the high altitude terrain. Bhutan has four distinct seasons in a year. The Indian summer monsoon begins from late-June through July to late-September and is mostly confined to the southern border region of Bhutan. These rains bring between 60 and 90 percent of the western region's rainfall. Annual precipitation ranges widely in various parts of the country. In the Northern border towards Tibet, the region gets about forty millimeters of precipitation a year which is primarily snow. In the temperate central regions, a yearly average of around 1,000 millimeters is more common, and 7,800 millimeters per year has been registered at some locations in the humid, subtropical south, ensuring the thick tropical forest, or savanna. Bhutan's generally dry spring starts in early March and lasts until mid-April. Summer weather commences in mid-April with occasional showers and continues to late June. The heavier summer rains last from late June through late September which are more monsoonal along the southwest border. Autumn, from late September or early October to late November, follows the rainy season. It is characterized by bright, sunny days and some early snowfalls at higher elevations. From late November until March, winter sets in, with frost throughout much of the country and snowfall common above elevations of 3,000 meters. The winter northeast monsoon brings gale-force winds at the highest altitudes through high mountain passes, giving Bhutan its name - Drukyul, which means Land of the Thunder Dragon in Dzongkha (the native language).
