Cambodia in September falls squarely within the latter half of the monsoon season. This period is characterized by high humidity, frequent rainfall, and warm temperatures. Daily averages typically range between 27C and 32C (81F and 90F), while humidity levels can exceed 90%. Rainfall, while often heavy, tends to come in short bursts, interspersed with periods of sunshine.
Understanding the climatic conditions prevalent during this month is crucial for travelers and residents alike. Agriculture, a cornerstone of the Cambodian economy, is significantly influenced by the monsoon rains. The Mekong River, vital for transportation and irrigation, is also affected by the increased rainfall. Furthermore, planning activities, choosing appropriate clothing, and understanding potential travel disruptions are essential for visitors during this time. Historically, September has marked a period of transition between the peak of the monsoon and the drier months to follow, impacting local customs and practices.
