Weather-wise and geographically, Vietnam is unusual. With rolling hills, plains and great beaches it is a country of contrasts and its weather reflects this dual personality. With Vietnam adventure tours, you will have opportunity to experience all features of the beautiful country.
Unlike most other countries of a similar size, Vietnam extends across two climatic zones, with a moderate climate in the North, and a tropical climate in the South. Because of differences in latitude and the marked variety in topographical relief, the climate tends to vary considerably from place to place. During the winter or dry season, extending roughly from November to April, the monsoon winds usually blow from the northeast along the Chinese coast and across the Gulf of Tonkin, picking up considerable moisture. Consequently, the winter season in most parts of the country is dry only by comparison with the rainy or summer season. The average annual temperature is generally higher in the plains than in the mountains, and higher in the south than in the north. Temperatures vary less in the southern plains around Ho Chi Minh City and the Mekong Delta, ranging between 21 and 28 °C (69.8 and 82.4 °F) over the course of the year. Seasonal variations in the mountains and plateaus and in the north are much more dramatic, with temperatures varying from 5 °C (41.0 °F) in December and January to 37 °C (98.6 °F) in July and August.
The country measures more than 1,650km from North to South with a coastline about 2,000km long, covering an area of 329,560 square kilometres. Laos and Cambodia share its western borders, with China to the North, and the South China Sea to the East and South. There are five distinct geographic regions: the mountainous north with peaks above 3,000 metres; the Red River delta of Hanoi; the Annamite Mountain Range, which divides North and South; the narrow coastal strip between the Annamite Mountain Range and the South China Sea, and the Mekong delta in the South.
