Weather in Cambodia in September

Cambodia's varied topography, including mountains, plains, and coastal areas, results in different weather conditions. In September, high-altitude areas such as the Cardamom and Dangrek Mountains tend to be cooler than the hot summer months, while the weather remains warmer in the lower areas, especially in the busy plains. Let's break down the specifics of the weather in Cambodia in September.

What is the weather like in Cambodia in September?

The weather in Cambodia in September is characterized by the continuation of the monsoon season, characterized by high humidity and frequent rainfall. During this time, the country experiences heavy downpours that can last for several hours, usually in the afternoon or early evening, followed by clear and sunny weather.

Heavy rainfall can affect travel plans and can also result in muddy paths and waterlogging, making some attractions difficult to access. Traffic can be slow due to wet roads, and boats are more likely to be used in flooded areas.

September is considered part of the low season in Cambodia due to the monsoon. During this time, there are fewer tourists, lower prices, and more accommodation options. This is the perfect time if you are looking for a more authentic and relaxed experience as the main attractions are less crowded.

September sees a lot of rainfall, which encourages the greening and filling of lakes and rivers, which can be particularly scenic. However, this can lead to localized flooding in some areas.

Overall, September may suit you if you are prepared for rain and want to explore the country without the crowds of tourists. However, due to the unpredictable weather, you need to pack properly and be flexible with your travel plans.

Temperatures in Cambodia in September?

Cambodia in September sees average high temperatures of 30 to 32°C (86-89°F) and average low temperatures of 24 to 26°C (75-78°F). These temperatures can vary from region to region: coastal areas and lower altitudes can be slightly warmer, while higher altitudes such as the Cardamom and Dangrek Mountains can be cooler, especially at night.

This weather in Cambodia in September indicates that the country remains quite hot although frequent rainfall can provide temporary relief from the heat. However, the high humidity levels can make it feel warmer than it actually is.

This is a transitional period from the sweltering summer to the slightly cooler fall months, but overall the climate is still considered hot, especially during the daytime.

So although September in Cambodia is not as hot as the peak summer months, it is still warm and humid, so it is important to remember to stay hydrated and wear appropriate breathable clothing.

What about crowds and costs

September in Cambodia sees fewer tourists due to the monsoon season, resulting in fewer crowds, especially at major attractions such as Angkor Wat. This allows for a better experience of the country's historical and natural attractions. Also as a result of lower demand, the cost of accommodation, excursions, and other services are usually reduced, making September one of the most budget-friendly times to visit.

September contrasts with the high season from November to March when the weather is drier and cooler, but prices are higher and tourist spots are crowded. The lower number of tourists provides a unique opportunity to experience Cambodia's rich culture and landscapes without the hustle and bustle, offering better interaction with locals and a calmer environment.

So despite the rain, the combination of fewer tourists and low prices makes September an attractive option if you are looking for a more relaxed and affordable travel experience.
