Why You Should Visit Cambodia In September? - Weather, Festivals & Travel Tips

What is the weather like in Cambodia in September?

Cambodia remains warm and tropical throughout September, with temperatures that are moderated slightly by regular rainfall. Average daytime highs range between 30–32°C (86–90°F), while nighttime temperatures settle around 24–25°C (75–77°F).

The overall feel is hot and humid, especially in the afternoon when the sun breaks through the clouds. However, mornings are generally more comfortable and ideal for sightseeing or outdoor activities before the humidity intensifies later in the day.

Besides that, September is among the wettest months of the year in Cambodia, with frequent but short and intense rain showers.

• Rainfall range: 200–300 mm across the country
• Rain frequency: Almost daily, often in the late afternoon or evening
• Sunlight: 4–6 hours of sunshine per day, mostly in the morning

And thanks to the frequent rain, the landscapes turn lush and vibrant, offering a stunning backdrop of green rice fields, full rivers, and blooming vegetation - a dream for photographers and nature lovers.

Tourist crowds are at their lowest during this month leads to iconic sites like Angkor Wat feeling quieter and more serene, allowing for a more intimate experience. On Tonlé Sap Lake, the high water level brings life to the floating villages, making boat tours more scenic and immersive.

Additionally, this off-peak season offers excellent travel deals, with lower prices for hotels, tours, and flights, which is ideal for budget-conscious travelers looking to explore Cambodia in a more authentic and relaxed atmosphere.

Festivals & Events in Cambodia in September

September marks the beginning of Pchum Ben, one of Cambodia’s most sacred and meaningful Buddhist holidays. Although the three main days of the festival often fall in early October, the 15-day observance period (called Dak Ben) typically begins in mid-to-late September. During this time, Cambodians gather at pagodas to make food offerings and pray for their ancestors. Visitors can respectfully observe or even take part in early morning ceremonies at temples, especially in rural provinces.

While September isn’t packed with large-scale public events, it offers a quieter, more spiritual window into local life. In some regions, especially around Battambang or Kampong Thom, you may also come across community events, harvest-related rituals, or local markets that feel especially lively thanks to the rainy-season abundance. Art spaces in Phnom Penh or Siem Reap may also hold seasonal performances, exhibitions, or cultural evenings geared toward expats and curious travelers.

Top places to visit in Cambodia in September
