Cambodia’s diverse topography—ranging from mountains and plains to coastal areas—results in varied weather conditions. In September, the high-altitude regions, such as the Cardamom and Dangrek Mountains, experience cooler temperatures compared to the hot summer months. However, the weather remains warm in the lower-lying areas, especially in the busy plains. Let’s take a closer look at the specifics of Cambodia’s weather in September.

 

What is the weather like in Cambodia in September?

September is firmly in the monsoon season in Cambodia, characterized by high humidity and frequent rainfall. Expect heavy downpours, typically occurring in the afternoon or early evening, followed by clear, sunny skies. While the rains can provide a refreshing break from the heat, they can also disrupt travel plans by making some attractions harder to access. Wet roads can slow traffic, and flooded areas may require travel by boat.

As September is part of the low season, there are fewer tourists, lower prices, and more accommodation options available. If you’re looking for a more authentic and peaceful experience, this is a great time to visit, as the main attractions tend to be less crowded.

The heavy rainfall also encourages the country’s lakes and rivers to fill, which adds to the scenic beauty, though it can cause localized flooding in some areas.

Overall, if you're prepared for rain and want to explore Cambodia without the usual crowds of tourists, September could be a good choice. However, due to the unpredictable weather, it's essential to pack appropriately and remain flexible with your travel plans.

Temperatures in Cambodia in September

In September, Cambodia experiences average high temperatures between 30 to 32°C (86-89°F) and average low temperatures around 24 to 26°C (75-78°F). These temperatures can vary depending on the region: coastal and lower-altitude areas can be slightly warmer, while areas of higher elevation, like the Cardamom and Dangrek Mountains, can be cooler, especially at night.

Though the country remains quite hot, the frequent rain provides temporary relief from the heat. However, high humidity can make it feel warmer than the actual temperature.

September marks the transition from the intense summer heat to the slightly cooler fall months, but the overall climate is still considered hot, particularly during the day. Remember to stay hydrated and wear breathable clothing to stay comfortable.

Is September a good time to visit Cambodia?

While it is the wet season, September can still be an excellent time to visit Cambodia for several reasons. The relatively low number of tourists means you can explore popular sites like Angkor Wat with fewer crowds. Additionally, the lush scenery—enhanced by the rains—offers stunning views and a vibrant natural environment. Plus, fewer tourists lead to lower accommodation and tour prices.

However, rain can cause disruptions, such as muddy roads and occasional flooding, and may require adjustments to your travel plans, particularly if you’re interested in outdoor activities. Indoor attractions and cultural experiences, however, remain unaffected by the weather.

Overall, if you don’t mind the rain and are looking for a less crowded and more affordable trip, September is a great time to visit. It’s an ideal month for travelers who are flexible with their plans and interested in enjoying the country's natural beauty at its peak.

What about crowds and costs?

September in Cambodia sees fewer tourists due to the monsoon season, making for a more peaceful experience at major attractions like Angkor Wat. This translates to better opportunities to experience Cambodia’s historical and cultural sites without the usual crowds.

Additionally, with lower demand, accommodation, tours, and services are generally more affordable, making September one of the most budget-friendly months to visit. In contrast to the high season (from November to March), which features drier and cooler weather but also higher prices and larger crowds, September offers a quieter, more relaxed atmosphere.

So, despite the rain, the combination of fewer tourists and lower prices makes September a great option for a more affordable, peaceful experience in Cambodia.
