Climate of Vietnam

Vietnam has a monsoon-influenced climate typical of that of mainland Southeast Asia.:25 The diverse topography, long latitude (Vietnam spans over 15° of latitude), and influences from the South China Sea lead to climatic conditions varying significantly between regions of Vietnam. The northern region experiences a monsoonal and humid subtropical climate with four distinct seasons (spring, summer, autumn, and winter) with winters typically dry and summers ranging from hot to mild. In southern and central areas, the climate is tropical monsoon with only two seasons (rainy and dry). In addition, a temperate climate exists in mountainous areas, which are found in Sa Pa and Da Lat, while a more continental climate exists in Lai Châu Province and Sơn La Province.

According to Indra Overland (2017), 20% of Vietnam's total surface area is low-elevation coastal area, making the country highly vulnerable to climate change effects and the rising sea levels in particular. From 1960 to 2011, high increases of 0.24 °C and 0.28 °C per decade are found at Vung Tau and Ca Mau stations, respectively, located in the South Coast. Most of the stations in the North - Central Coast show an increase of 0.15 °C to 0.19 °C per decade. From 2007 to 2008, the flooding in the central provinces exceeded that of past 48 years; the northern part of Vietnam encountered an unprecedented cold wave, lasting for 38 days, resulting in 30 million US dollars Crop and livestock losses.
