Weather in September

September signals a gradual retreat of the particularly heavy tropical monsoon climate in Kampong Kdei. Conditions trend slightly towards drier days with a minor decrease in average temperatures. Offering the highest rainfall of the year at 257mm (10.12") combined with high humidity, September remains reliably consistent with the Cambodian monsoon weather. The subsequent transition toward October brings with it noticeable changes in terms of rainfall and temperature. Despite these changes, visitors during this period are advised to anticipate the monsoonal conditions to continue.

Temperature

Upon the beginning of September, Kampong Kdei's high-temperatures register at a still hot 31.2°C (88.2°F), closely mirroring the preceding month. The average nighttime temperature lowers to a warm 24.7°C (76.5°F) throughout September.

Heat index

The heat index value during September is calculated to be a blistering 42°C (107.6°F). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.
In the scope of the heat index, its values resonate with shade and light wind conditions. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'feels like', comes about by integrating the temperature readings with the humidity levels. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
