Cambodia

Cambodia has a tropical climate with two distinct seasons. The best time to visit Cambodia is during the dry season, which runs from November to April. During this time, temperatures are cooler and there is little rainfall. The peak tourist season in Cambodia is from December to February, so expect larger crowds and higher prices during these months. If you prefer fewer tourists and lower prices, consider visiting in the shoulder months of November or March.

Vietnam

Vietnam has a diverse climate due to its long and narrow shape. Generally, the best time to visit Vietnam is during the spring (February to April) or autumn (August to October), when temperatures are milder and rainfall is lower. These seasons offer pleasant weather for exploring both northern and southern Vietnam. The summer months (May to July) can be very hot and humid, while the winter months (November to January) can bring chilly temperatures, particularly in the north.

Cambodia & Vietnam

Both Cambodia and Vietnam experience a monsoon season, which brings heavy rainfall and high humidity. In Cambodia, the monsoon season occurs from May to October, while in Vietnam, it extends from May to September. During this time, travel can be challenging as roads may become flooded, and some attractions may be inaccessible. However, if you don't mind the rain and want to avoid the crowds, visiting during the monsoon season can offer a unique experience with lush landscapes and cheaper prices.

In terms of cultural events, Cambodia celebrates Khmer New Year in mid-April, which is a lively time to visit and experience traditional festivities. Vietnam's major festival is Tet, the Vietnamese New Year, which takes place between late January and early February. It is a significant holiday where locals celebrate with family gatherings, fireworks, and various customs.

Ultimately, the best time to visit Cambodia and Vietnam depends on your preferences. If you enjoy warm weather and want to avoid the rain, plan your trip during the dry season. If you want to experience unique cultural celebrations or prefer fewer tourists and lower prices, consider visiting during the shoulder or monsoon seasons. Regardless of when you choose to visit, both Cambodia and Vietnam offer rich history, stunning landscapes, and warm hospitality that will make your trip truly memorable.
