Ho Chi Minh City's climate is classified as tropical wet and dry, meaning that it is warm all year round and divided into two distinct seasons, the wet season and the dry season, rather than spring, summer, fall and winter. The rainy season lasts from May through October, and the dry season runs from December to April.
By Plane: Tan Son Nhat (Tân Sơn Nhất) (IATA: SGN | ICAO: VVTS) is Vietnam's largest international airport. There are two terminals: the shiny, pleasant international terminal which took over all international flights from 2007, and the old but functional domestic terminal 200 metres away. The airport is conveniently located about eight kilometres from the heart of the city. The international terminal used to offer duty free shopping after you landed, but that ended in early 2010 – purchase such items at the airport from which you are departing to visit Vietnam. Both terminals have limited food offerings at high prices once you pass immigration on your outbound journey. Note that airport shops and food outlets past immigration list prices in US-Dollars, and will take your Dong at grossly unfavorable rates. Thus, do not plan on spending any leftover dong at the airport.
The best way of all to see Ho Chi Minh City is on foot. Most major tourist venues are in District 1, which is fairly compact and easy to maneuver. Taxis are all metered and very inexpensive. You can get across town for about $2 or $3. Xe om (motorbike taxis, pronounced ‘‘see ohm’’) are even cheaper. Cyclos (pedicabs, pronounced ‘‘see-klos’’) carry only one passenger at a time. They are slow and somewhat uncomfortable, yet more charming and intimate way to experience the pace of modern Ho Chi Minh City. Unfortunately, they are being slowly squeezed out central Saigon by traffic.
