Weather in Cambodia in May

Cambodia's varied temperatures and climates may seem peculiar for a country that is not large. The country’s landscape includes mountains, lowlands, and coastal areas, so temperature variations shouldn’t come as a surprise. The Cardamom and Dangrek Mountains have cooler temperatures than the lower-lying plains, home to most of the country’s towns and cities. For now, we’ll take a deep dive into the weather in Cambodia in May.

What is the weather like in Cambodia in May? 

May is characterised as the transition month between the dry and wet seasons. The weather in Cambodia in May is generally warmer with noticeably high humidity levels, which contributes to the climate's tropical feel.

As the first month of the monsoon in Cambodia's southwest, May is the time when there is an increase in rain with a chance of thunderstorms. The weather tends to be rather unstable, varying between hot and cool, dry and humid and occasional showers. May tends to be slightly cooler and still fairly dry compared to April. 

Overall, May is still a good month to travel if you enjoy the charm of the rain and want to avoid peak-season crowds. This is when Cambodian landscapes become vibrant, offering beautiful sceneries. We advise packing a waterproof jacket and planning indoor activities for the rainy days when you won't be able to enjoy the outdoors.

Festivals and events in Cambodia in May

May in Cambodia is not known for any major festivals except for the ancient agricultural ritual known as the royal ploughing ceremony. This is not an event that draws in a major number of tourists, but it offers a glimpse into the country’s cultural heritage.
