Weather in December

With December comes the completest transformation of the weather in Treas, Cambodia. The weather evolves to its driest phase and the temperatures drop to their coolest for the year. Reduced cloud coverage allows for more hours of sunshine despite the shorter days. An increase in wind speed serves as a cooling factor for the relatively warm temperatures. The most notable element for this month is the significant drop in average rainfall, standing at a year low of 11mm (0.43").

Temperature

The coldest month is December, with an average high-temperature of 30.5°C (86.9°F) and an average low-temperature of 20.3°C (68.5°F).

Heat index

For December, the heat index is evaluated at a sweltering 35°C (95°F). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.
Given the heat index, its values are aligned with shaded sites and gentle winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve cooling. 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. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Take precautions and utilize sun safety practices. Protection against skin and eye damage is required. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Safeguard your eyes, ears, and face from sun rays with the aid of a wide-brim hat.
