Viet Nam stretches for 3,260 km along the Gulf of Tonkin and the South China Sea, covering the Mekong Sub-region’s east boundary. Its west border runs along the east sides of Laos and Cambodia, and China caps its north border.  Vietnam covers 329,560 km², with mountains and hills in the north dominating three-quarters of the landscape. The fertile Mekong Delta in the South covers 10 % of the country’s area where the final 200km of the Mekong River flows into the sea through Cuu Long or Nine Dragons.

The country is divided into five distinct geographic regions:  the northeast mountains of Viet Boc stretch from the Red River to the Gulf of Tonkin, the northwest mountains run from the Chinese border to Laos, the Annamite Mountain Range forms the backbone of the central region, while beaches trim the east and the Mekong Delta characterises the south.

Viet Nam’s climate ranges from temperate in the north to tropical in the south.  The four seasons are evident in the far north where occasionally winter temperatures can drop dramatically during the night. The cool season in the north is from November to April.  The southern climate is similar to that of other Southeast Asian countries: warm and dry from November to January, hot and dry from February to May, hot and rainy from June to October with an occasional typhoon.
