Temperature

The commencement of December notes an average high-temperature of a still tropical 31.2°C (88.2°F), exhibiting little difference from the previous month. In Anakao, the expected average low-temperature for December is a moderately hot 24.8°C (76.6°F).

Heat index

The heat index in December is computed to be a torrid 37°C (98.6°F). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.
Heat index evaluations are typically in the context of light winds and shaded environments. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. It is noteworthy that being in direct sunlight can enhance the weather's impact, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Under high air temperature and high humidity (high heat index) conditions, the body's ability to perspire is compromised, increasing the sensation of heat. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.

Uphold preventive measures and conform to sun safety guidelines. Defending against skin and eye harm is crucial. To the best of your ability, limit your exposure to the sun between the hours of 10 a.m. and 4 p.m., when UV radiation is at its peak. On sunny days, it's ideal to wear sunglasses that filter out UVA and UVB rays. Heed this! UV intensity is much stronger when reflected off sand and water.
