Vietnam is positioned on top of the equator so it is mostly tropical all year long. In the south of Vietnam(Saigon/ Ho Chi Minh City) where the wedding ceremony, and wedding reception take place, it is warm all year. In the month of December, temperature is approximately 70-85 degrees Fahrenheit. In the north of Vietnam, there are 4 seasons. If you are planning to visit other parts of Vietnam, especially north (Ha Noi), I recommend you bring appropriate attires. To best of your comfort, please check the weather in all regions you plan to travel to, in Vietnam.
