Climate Features

Ben Tre province is located in the subequatorial zone, characterized by strong monsoon influence and rather high and stable temperature all year round, ranging around 26oC and 27oC, all above 20oC. On the yearly basis, the province witnesses the Sun passing the zenith two times on April 16th and July 27th.

Being in the tropical zone also endows Ben Tre with a majority of sunny days in the year and a large amount of radiation, averaging at 160kcal per cm2 of ground surface. Though it is located ashore the South China Sea, Ben Tre is generally not affected by tropical storms and typhoons from the Pacific Ocean as much as other parts of Viet Nam, especially the Middle and the Northern Coasts. One reason is that its geographical location is at low latitude (between latitudes 9o and 10o North) while storms and typhoons most usually take place at latitude 15o North up. Seafront position also is the important factor to hold the yearly temperature differences in small margin.

Like other Southern provinces, Ben Tre has two distinguished seasons in the year. The cold (dry) season, typical of cold North-Eastern wind, is lasting from December to April of the next year. Then comes the hot (wet) season from May to November, with a lot of rain and high humidity as a result from the influence of tropical monsoon (South-Western wind). During the wet season, the rainfall is hovering as high as 1,250 mm to 1,500 mm, while in the dry season, this is as little as 2% to 6% of the whole year.

There are advantages and disadvantages stemming from this climate pattern. Much exposure to sunlight, high temperature and humidity are good for photosynthesis and reproduction of plants and livestock. Disadvantages, however, caused by those good features themselves, resulting in the development of pests, diseases, and an assortment of fungi all year round. Moreover, the dry season also causes the biggest problem: the invasion of salt-water leading to the shortage of fresh water for production and clean water for living activities. Worse, the shortage of fresh water causes bad effects on cultivation and life in seaside areas.
