The best place in Southeast Asia to witness the convergence of the old and new is Vietnam. It shows the contrasting characteristics, from historical past to modern developments as well as diverse landscapes and people that will leave a lasting impression.

Landscape: 

A long, skinny country curled around the East Sea, Vietnam has 3,450km of coastline and a central spine of mountains, including the highest peak in mainland Southeast Asia, Mount Fansipan.

Vietnam’s shape is often compared to two rice baskets on a shoulder pole. The narrow band of lowland deserts and steep mountains in the center give way to broad expanses of river deltas in the north and south. Having begun its journey in Tibet, the Mekong River divides into nine tributaries and feeds the agricultural region of the Mekong Delta. Meanwhile, the Red River Delta is the economic center of the northern region notably known for farming and villages specializing in producing handicrafts.

Vietnam boasts amazingly varied landscapes; from precipitous mountains to uncharted forests, from emerald terraced rice fields to deserted pristine beaches. While large resort developments are heavily concentrated along the stretch of East Sea in Danang, there are still many parts of the country that remain untouched like the castaway islands of the Con Dao archipelago, an ideal getaway for those seeking an off the beaten path experience.

Climate:

In general, Vietnam has a tropical climate with average annual temperatures ranging from 22˚C (72˚F) to 30˚C (86˚F). There are two distinct seasons: wet and dry. From April to October, most of the country is affected by south-western monsoons. The rains, which tend to be concentrated in the late afternoons, provide welcome relief to the heat. Travel to very remote areas may be affected by the rains, but overall they should not interfere with your trip.

Packing for a trip to Vietnam can be challenging, as the climate can vary depending on when and where you go. When the weather isn’t ideal in one area, it’s great in another. While Hanoi is cold enough to warrant a coat from December to February, this is an excellent time to visit Ho Chi Minh City and the Mekong Delta. Although the temperatures are consistent year round, various parts of the country, at certain times of the year, can be affected by unpredictable storms which may cause flooding.

Time zone:

Vietnam operates on Greenwich meantime +7 hours. Vietnam does not observe daylight saving hours.
