Temperature

December's arrival registers an average high-temperature of a still tropical 31.2°C (88.2°F), closely aligning with the temperature of the previous month. Namu experiences an average temperature drop to a pleasant 21.2°C (70.2°F) during December nights.

Heat index

December's average heat index is appraised at a sweltering 35°C (95°F). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.
Observations indicate that the heat index values are for shady locations with light wind. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
