Cambodia in September will be perfect for those who don’t mind traveling with some opportunity of rainfall, but in return with lush landscape and fewer crowds. While the month falls within the monsoon season, it presents an extraordinary opportunity for adventurous travelers seeking authentic experiences, fewer crowds, and stunning landscapes. Let’s dive into why September might just be the perfect time to explore this magical Southeast Asian destination.
What is the September Weather in Cambodia Like?

September in Cambodia unveils a mesmerizing metamorphosis of the landscape, characterized by its dynamic monsoon climate that breathes life into every corner of the country. The weather during this month is a captivating dance of rain and sunshine, creating an environment that is both challenging and incredibly beautiful for travelers.
Temperatures hover consistently between 30-32°C (86-89°F) during the day, with nighttime temperatures dropping slightly to 24-26°C (75-78°F). The high humidity adds an extra layer of warmth, often making it feel more intense than the actual temperature suggests. This creates a climate that is:
- Warm and humid
- Consistently tropical
- Characterized by quick temperature shifts
- Ideal for those who enjoy a subtropical atmosphere
Rainfall is the star of September’s weather show. Unlike popular misconceptions about monsoon seasons, the rain in Cambodia is not a continuous deluge but rather a dramatic performance of nature. Typically, rainfall occurs in the afternoon or early evening, presenting a predictable pattern that smart travelers can easily navigate. Expect:
- Heavy but short-lived rainfall
- Occasional dramatic thunderstorms
- Rapid clearing with brilliant sunshine breaking through
- Periods of clear skies between rain showers
The continuous rainfall transforms Cambodia into a photographer’s paradise. Rice paddies burst into vibrant green, lakes and rivers swell to their fullest, and temple moats create stunning reflective surfaces that mirror the sky and surrounding landscapes. This natural phenomenon brings several unique characteristics:
- Lush, verdant landscapes as far as the eye can see
- Filled water bodies creating perfect reflection opportunities
- Increased agricultural activity
- A sense of renewal and growth across the countryside
Regional variations add another layer of complexity to September’s weather. Coastal areas and lower plains maintain warmer temperatures, while higher altitude regions like the Cardamom and Dangrek Mountains offer a cooler respite, especially during nighttime. Rural areas might experience more prolonged rainfall, adding an element of unpredictability to the travel experience.
Is It Worth Going to Cambodia in September?
Absolutely! Despite the rain, September offers compelling reasons to visit. For travelers, this means packing versatile clothing, being prepared for sudden weather changes, and embracing the beautiful unpredictability of Cambodia’s September climate. The reward is a landscape at its most alive, vibrant, and breathtaking:
