Lying south to the Tropic of Cancer, Vietnam is warm and humid nearly all year around, with average annual temperature of about 24℃ (75 ℉). Possessing a long and narrow terrain spanning over 1,650 km (1,025 mi) from south to north, Vietnam’s unique geography endows it with different types of climates. The average annual temperature in plains is usually higher than that in mountains and plateaus. Northern Vietnam is cooler with the highest temperature of 37℃ (99 ℉) and the lowest one of 5℃ (41℉). Temperature ranges from 21°C (70℉) to 28°C (82℉) all year round in the south.
Seasonal differences in northern Vietnam are more obvious than in the south. Four distinct seasons can be observed in the north, while most regions of the country are characterized by dry and rainy seasons. The dry season starts from November to April, when monsoons usually blow from the northeast along the coast of China across the Gulf of Tonkin, driving away much of the moisture and bringing a little rainfall. During the rainy season between May and October, the moist air is blown in from the southwest Indian Ocean, bringing abundant rainfall and sometimes even typhoons and storms. The annual rainfall varies from 1,200 mm to 3,000 mm in different regions across Vietnam but mostly happens in the rainy season.
